The EAATC Fire Station 3D Modeling Process Illustrated

Part IV


 

 

St. Paul Former Station 14 (b) Modeling Illustrated

In late January, 2013 we began development of our 35th Fire Station model, that of the StPFD Former Station 14 (b). That stations location is at #91 N. Snelling Ave, in St. Paul, Minnesota. The building (although altered) is exists.

That station was this authors 'home' station when I was a much younger man. After 34 other fire station models I thought it might be interesting to some to explain our process used to produce these models.

You can model this very same station, and follow along with the examples, or, model your own house, or other building of your choice. If you follow along and build this station with me, I'd be very interested to view your results.

We are going to model ONLY the outside of the building. Doing a full inside/out structure requires a much more significant level of complexity when dealing with 3D drawing.


If you have questions or comments about this explanation go to our USER FORUMS and leave your questions.

This section takes our model from...

Numerous extrusions on station front around apparatus door areas. Near rooftop extrusions on station front and side. Raw layout, and completed brick arch for double front windows. The FIRE STATION extrusion with 3D indented text.

  Numerous differently sized windows and brick arches on the sides and rear, including a hay loft door and I-beam in the rear. Four entrance doors with arches on side an rear.

31. Create the windows for the station front
 

TASK: A set of windows must be created and then placed inside a recessed frame for the windows.

TH-not-found This older photo of the station shows the windows on front of station. They are placed in a recessed brick area, the size of which we determined earlier.

The windows have two 'sections'. The upper section appears to be a frame single panel window. And the lower section appears to be frame double hung window with single panel glass.


TH-not-found This is the shape and eventual position I'm speaking of.


TH-not-found Moving to our temp building (we're still going to do most of our construction there) drag a copy of the 8' Arch Raw Shape onto the building.

Hmmm. Whatever you do it doesn't want to seem to lay flat.

This is very common for components that are '2D' (have no depth) acting in a 3D world. Lets fix that.


TH-not-found My solution for an 'object' with no depth is simply to give it something attached that has depth.

So EDIT the component, you may even find this a bit tricky, as you have to select a line of it to edit. But clicking the line my be tough too. If so, select the component, and the EDIT/Component (x in Model) to edit it.

All I did was pan to a lower corner, and draw a small RECTANGLE, and then PULL it out a bit to give some depth. We'll delete this extra rectangle later.

Now exit editing.


TH-not-found Now select the component. The little rectangle now gives you an easy place to grab/move etc. as you need to.

ROTATE the component 90 degrees to get it to lay flat.

Then I re-edited the component, and deleted the rectangle.


TH-not-found Make this copy of the Window Shape UNIQUE!

Then I dimmed the shape to define where I desire things to be placed. Overall the total window area is 8' wide by 6' 1" high. In this space four window sections are to be created.

The upper set is going to be in an 18" space. And the lower in the remaining 4'7".

The window sections will each be 3' 11" wide, yielding a 2" free space in the center.


The windows we'll create are 'simplified' as they only require their 'outside' faces. We are not modeling the inside of the building, so only the outside must look accurate. And we're not going to create any fancy shaped moulding's either.

These windows are simple sets of recangles, offsets, and a series of push-pulls. Those steps require some care however.


TH-not-found Okay, a safe distance away from our shape draw a 3'11" by 6'1" rectangle.

Be accurate or the windows won't fit. Not about 3'11" by 6'1" but rather EXACTLY 3'11" by 6'1".

I've dimmed it just for reference.


TH-not-found OFFSET that rectangle IN by 3/4" (.75").

You've just created the 'Window Frame Box' that surrounds the window area.


TH-not-found Now INSIDE that offset (repeat, inside) draw two LINES horizontal (on red axis), one 18" down from the top, and the other at the midpoint of the remainder (2" 3 1/8").

Look closely at the photo.


TH-not-found In each of those 3 sections two offsets are required.

First OFFSET a section by 2". Then OFFSET that offset by .75" (3/4").

Then REPEAT the same for the remaining two sections.

You've just created the window frame, the moulding inside that to hold the glass, and the glass itself.


TH-not-found Now the push-pulls.

Now 9 times PUSH everything IN by 1".


TH-not-found In the upper two sections PUSH in the .75" offsets by 3/8".

Then the 'glass' by the same. And then the the glass itself by ANOTHER 3/8".


TH-not-found Now in the lower section PUSH all three offsets in by 2".

Why? Because you've just created the bottom window section. The that you typically raise/lower. Frame (wooden) window sections are 'usually' 2" thick. So in order to get the bottom section inside the upper section we move it in 2".


TH-not-found Now as you did above, each the two remaining offsets should be moved IN by 3/8" in relationship to each other.

See the photo.


TH-not-found There are four small lines like this you can ERASE. Look around on the 'sides' of the window. You'll find them.


TH-not-found Zoom out a bit. PAINT the 'glass' areas with the Translucent sections 'Translucent_Glass_Blue' choice.

And now you'll 'see through' the glass.

Kinda looks like a window. Yup, that's the idea.


TH-not-found Switch to X-ray and pan/zoom as required to ensure there's nothing 'behind' you.

Select the window and Make Component. I named mine 'Window Dbl Hung & 18" Top - 3'11" x 6'1" '.


TH-not-found From the Components Window drag a copy of the raw window shape from the Components Window.

Remember in step 6 of this section you were supposed to make the copy you dragged then unique, so you should still have a raw windows shape to drag.

If not, you'll have to draw a 8' x 6'1" rectangle, and give it an 8" arc at the top center.


TH-not-found Make this copy UNIQUE.

If you don't get a Make Unique choice, you need to temporarily drag ANOTHER copy of it, them make this one unique. Then you can delete the temporary copy.


TH-not-found EXPLODE it.


TH-not-found Ensure that the whole surface shape selects properly. Of not, re-draw edges until it selects.

Then PUSH it in by 4".


TH-not-found Switch to X-ray and pan/zoom as required to ensure there's nothing 'behind' you.

Select the windows shape and Make Component. I named mine 'Windows Dbl Hung 3'11" Frame'.


TH-not-found Now EDIT the Windows Frame.

Drag a copy of our window from the Components Window onto the open for edit frame.


TH-not-found Then MOVE the window's lower corner to the frames lower corner.

See the photo.


TH-not-found Next either COPY/MOVE, or drag another copy off the Components Window, and MOVE another copy of our window to the opposite corner.


TH-not-found And so far your windows should look like this.

We're not quite done with these windows yet, but we ARE very close. And will need a bunch of them!

32. Complete and place the three front window assemblies
 

TASK: Add the brick arch to the windows assembly, and create the finished complete window assembly. Then place 3 copies of the finished window assembly on the station front second floor.

TH-not-found I'd like a complete window to include the brick arch to ease the placement of the windows.

On our temp building where we should (if not, drag one off too) still have our Windows Dbl Hung 3' 11" Frame, drag off a copy of our Over Window 8' Brick Arch onto the building front.


TH-not-found MOVE the arch lower corner to the top corner of the windows.


TH-not-found Switch to ensure your 'background' is clear. Select the whole arch and windows assemblies.

Then Make Component. I named mine 'Window 8' w/Rnd Top & 8' Arch ASSY'.


TH-not-found PAN the station front. Select and DELETE the current window parts and arch there, either together or separately. Makes no difference.


TH-not-found We need a spot to place the center window assembly. You may recall the bottom of the windows are 6" ABOVE the top of the FIRE STATION logo extrusion. We need those 6" to create another extrusion, but that's for later.

From the top MIDPOINT OF COMPONENT of the station logo draw a 6" LINE up. It's the end of this 6" line that we'll 'connect' to.


TH-not-found Drag a copy of our complete window assembly w/arch off onto the station front. Close is good enough for now.


TH-not-found With the MOVE tool grab the bottom MIDPOINT OF COMPONENT of the windows assembly and drag it until it snaps to the end of that 6" locator line.


TH-not-found Recall that there is 2' space between the front windows. So...

Start a COPY/MOVE on the lower right hand corner of the windows.


TH-not-found Drag to the right maintaining the RED axis.

Drop the window anywhere on the red axis and ENTER 10'.

You'll have another copy of the window with a 2' spacing between them. Measure it to be sure if you desire.

You also could have drawn a 2' horizontal LINE from the right bottom corner of the first windows, and then snapped your corner of another copy of windows assembly to the end of that line. Your choice. Copy/Move is easier I feel.


TH-not-found Looks good.


TH-not-found Hmmm. All three. I know we spent a LOT of details to 'get here', but this EXACTLY WHY!!

Now we can place this window assembly where ever we need. And we WILL NEED IT.


TH-not-found And also now you can look inside our station. Have you tried zooming WAY in until you get INSIDE? Sure you can do it. Try it.

If you get 'lost' use CAMERA/ZOOM EXTENTS and you'll 'fly' back to outside.

And now our model looks like this.

33. Place 7 more instances of our windows
 

TASK: There are 7 more places that our windows with the arch are required. We'll put them in place now.

TH-not-found This view of the station side shows there are 3 more placements of our double windows required. Two on the left of the Hose Tower, and one on the right.


TH-not-found I've drawn a guide marking the window bottoms, and then used it to draw a LINE on the GREEN axis from the front corner to the side of the Hose Tower.


TH-not-found Then I am DIVIDING that line into 4 segments.


TH-not-found Then I drew two marker lines down from the endpoint's of the segment 1 and segment 3, to mark the window placement.


TH-not-found Drag a copy of the windows onto the station side near the marker line.


TH-not-found Then grab and MOVE the bottom 'Midpoint of Component' until it SNAPS to the upper end of the marker line.


TH-not-found I desire to draw a similar 'window bottom indicator' line on the opposite side of the Hose Tower.

You could draw guides to do it, but there's an easier way. Let SU help you! LOOK at the picture!

If you HOVER OVER the lower corner of the window while drawing a LINE, and then move your start position to the other side of the Hose Tower when your at exactly the same level you'll get a prompt from SU. Notice the thin dotted GREEN line and the BLACK DOT shown prompting your RED dot to in the same plane. Don't work harder than you have to.

Easy!


TH-not-found Draw a LINE on the GREEN axis over to the Chimney.


TH-not-found Then DIVIDE that line into 4 segments.


TH-not-found I then drew a marker LINE down at the end of the first segment. Then I erased the now unneeded horizontal line.

Then drag another copy of the window off the Components Window by clicking the small image of the window at the bottom center.

Now SU has gotten 'smarter' and it 'remembers' that the last time you placed it it was at the same elevation level sooooo...

It will SNAP the window to the end of the marker line for you, or at least it will TRY. If not, YOU do it.


TH-not-found Two things here. First I drew a GUIDE 42" up to 'mark' the bottom of any window located on the first floor.

Then I hovered over the bottom of the previous line we used to locate the first window here in order to get SU to give me an inference. Then I moved my mouse down (notice the dotted BLUE line) until I was over the guide and received a RED DOT.


TH-not-found And I drew a small LINE down from that point to 'mark' it.

Next I dragged another copy of our window onto the building side. SU will TRY assume if you grab the bottom center of the new copy, that you'd like it connected to the end of the small line.

If not, do it yourself.


TH-not-found Well our model so far looks like this.


TH-not-found Observing this StreetView image of the station it clearly shows 3 more of our windows located on this side.

In addition there is another one centered on the second floor of the Watch Office.

AND, if your observing closely there is another double window on the first floor level. But this window does NOT have the arch top. In addition it's top is located against a long 'header' on the building side, which we have not yet constructed.


TH-not-found Draw a GUIDE down the building and intersect with the guide marking the front window bottoms to carry the reference 'around the corner'.


TH-not-found Then draw a LINE on the GREEN axis following the guide from the right side of the Utility Chimney to the left side of the Watch Office.


TH-not-found Next draw small 'marking' lines two each 6' in from each end, and one down from the midpoint.

I've dimmed them for reference.


TH-not-found Now drag a copy of the window off grabbing the lower left-hand corner and place that corner at the upper end of the first marker.


TH-not-found And another for the right side, and one in the center.


TH-not-found Panning to the Watch Office side draw a GUIDE 10' down marking the window bottom elevation.


TH-not-found Then draw a LINE along the guide, and another small LINE down marking the midpoint.

Then drag another copy of the window, and center it.


TH-not-found And our model now looks likes this.


TH-not-found And like this.

34. Create 4' brick arch, and 4' wide windows
 

TASK: Some smaller windows are required and those need a 4' arch of bricks. The arch is easy, I've made it for you. You'll create the windows needed however.

TH-not-found This image from StreetView shows one of those 'smaller' 4' windows. And it's arch of bricks is clearly visible.

The window shown is new, not the style the station was constructed with. We'll do it the 'old' way.


TH-not-found But FIRST let's save another version. Backup. BACKUP BACKUP!

Mine is revision 9.


TH-not-found This 4' brick arch needed is created ABOUT the same way as our 8' arch. Unfortunately it's the ABOUT part (requiring some small deviations in the mortar spacing) that are just not worth the time explaining here. So, I've already created the 4' arch for you. Just right click the link and download the small .skp file.

I'm showing it here and I started the window opening by drawing a LINE down 6' 1" from the left bottom corner of the arch.


TH-not-found Then start drawing LINE on the RED axis, using the reference point of the opposite arch corner as your 'limiting' point.


TH-not-found MOVE the arch away.

Complete the rectangle.

Then draw a LINE up 8" from top midpoint of the rectangle. This establishes the 'bulge' for the arc of the window opening.


TH-not-found Draw an ARC from the top rectangle corners using the end of the bulge line for the height. Enter 96s so you get a smooth arc (and to match the supplied brick arch's arcs).


TH-not-found ERASE the line across the top. Ensure the window outline SELECTS. Re-draw edges if needed.

Then PUSH it in by 4".


TH-not-found First re-draw the line from 'arc corner' to corner. Be careful, zoom, pan, orbit to be SURE getting the inside corners correctly. This IS a place to go wrong!

Then draw a GUIDE 18" from this line, as shown.

Then OFFSET the rectangular area IN by .75" (3/4"). Look carefully at the photo.

This defines the window box frame.


TH-not-found Draw a LINE across the 18" guideline. Be careful it's from the INSIDE of offset area NOT the window outside.

And then another line from the midpoints of the remaining side vertical line.


TH-not-found Then 3 OFFSETS each on the upper AND middle panel.

They 2", followed by 3/4", and another 3/4".

See the dimmed photo for reference.


TH-not-found Then a series of PUSHES on both the upper and middle panel until you achieve the surfaces dimmed for reference.


TH-not-found Zoom out. We need to PAINT the 'glass'.


TH-not-found Switch to X-ray to ensure your 'clear' behind.

Select the window and Make Component. I named mine 'Window 4' x 6'1" w/Rnd Top'.


TH-not-found Next I've selected the brick arc, and I'm MOVING it's corner into position at the left upper corner of the window.


TH-not-found Then select the window and the arch and Make Component.

I named mine 'Window 4' x 6'1" Rnd Top w/Arch ASSY'.


TH-not-found So far our model looks like this.


 
Return to Top

 
none
35. Place several more 4' windows. Add building side flat 'concrete' marker. Adjust and fix the Watch Office small roofs.
 

TASK: Several more of our 4' windows are needed to be placed.

Close observation has detected an omission of a 'concrete' building side marker strip. That marker strip requires the roof area and surround extrusion of the Watch Office to be modified.


TH-not-found Two more of our 4' wide windows need to be placed on the second floor station side. You may still have the marker lines we drew previously. If not I've added some dims for reference.


TH-not-found Drag another copy of the 'Window 4' x 6'1" Rnd Top w/Arch ASSY' onto the building side. If you grabbed the middle bottom it MAY snap right into place. If not just MOVE it to it's correct location.


TH-not-found Repeat the process with the second window.


TH-not-found Yours should look like this.


TH-not-found Using the window bottoms guide I draw a LINE across the building side (above the 'steps' area). Then I drew a small marker line down from that LINES midpoint. I then ERASED the line leaving only the marker.

Drag another copy of our 4' window into position.


TH-not-found This portion of a StreetView image shows that there is what I call a 'concrete' stripe underneath the extrusion we previously created surrounding the Watch Office. I 'missed' it. It happens.

If you follow it's lines around the sides of the station towards the front you'll see it is aligned with the edges of the extrusion portion on the front that will eventually hold the 'company names'.

We need to create that, AND relocate the Watch Office extrusion. In addition we'll need to recreate the small roofs to include the 2" reveal that's visible.


TH-not-found First let's MOVE the Watch Office extrusion out of the way.

We made it a component when we created it. Why? For just this reason. If we had created 'by hand' by doing a bunch of push-pulls, you would now be going through the agony of trying to delete it, and then re-create it.

Lesson learned. There IS method to my madness.


TH-not-found Starting at the station front extrusion I've drawn a bunch of GUIDELINES showing where the 'concrete' stripe we need should be located.


TH-not-found Then I drew LINES to define the surfaces and selected them for your reference.


TH-not-found Continue the process around the Watch Office and onto the station middle side.


TH-not-found I was unsure whether or not stripe continued around the Utility Chimney and continued to the station rear corner.

This StreetView answered my questions. You have to look close, but the stripe continues around the chimney and to the building corner.

And it also illustrates that the first floor windows do NOT have brick arches over them.

The stripe has faded over the years since 1910's construction so you must look closely.


TH-not-found Instead of guides I decided to draw LINES, paying attention to the RED and GREEN axis, to continue the stripe.


TH-not-found Your stripe should look like this.


TH-not-found Draw a LINE across the station rear. Then DIVIDE it by 4.


TH-not-found Draw 2 marker LINES down in the first and third positions. Then ERASE the horizontal line.

Now drag another copy of our 4' window and place it.


TH-not-found Now the other window too.


TH-not-found Back to our Watch Office roof.

First I ERASED the roof peak of the roof. Then the angled side lines too.


TH-not-found From the outside rear corner I drew a LINE up 14".

Then from the 12" point of that line I drew lines around the sides indicating the height level of the new roof.


TH-not-found Then another LINE on the RED axis to the outside corner.


TH-not-found Grab the inside corner of the extrusion. Get ready to MOVE it.


TH-not-found MOVE it to the TOP edge of the station corner.


TH-not-found Now we need that new 2" reveal for the roof. I'm just going to draw a few LINES to construct it.

Why not just PULL the roof up by 2". That would work also. Your choice.


TH-not-found Complete your 2" roof reveal. Then I desire a 12" height in the rear corner. For me that's up 14" from the lower corner. If you PULLED yours up by 2" that's 12" up from the rear corner.

Draw the diagonal lines from that point to the outside corners.


TH-not-found Then another diagonal corner to corner to complete the roof peak.

Then repeat the whole process to create a new roof on the opposite side too.


TH-not-found Now your model looks like this.


TH-not-found And like this also.

36. Add more 4' windows. Create and place two 8' flat top windows. Create a 2'8" window.
 

TASK: We need to place an additional 4' window. The first floor windows do not have arches or rounded tops. We'll create a flat top window by modifying a round one. The station also requires a 2'8" wide window. We'll create it.

TH-not-found I've drawn a GUIDE up from the base to 'window bottom' level. Then another 3' in from the station front.

Place another 4' windows bottom corner at the intersection of these guides.


TH-not-found The station requires several of our 8' double windows. However these require no arch or rounded tops. We'll modify a copy of or window parts.

Locate in your Components Window the pair of 3'11" windows in the rounded top window inset frame. Drag a copy of it to the front of your temp building.


TH-not-found Make this copy of the windows UNIQUE!

Repeat, make this copy of the windows UNIQUE!

If you don't we will be changing ALL of previously placed windows. And you DO NOT DO NOT DO NOT want that to take place!


TH-not-found Open the Entity Info window for this component. We'll alter it's name into what it's going to become.

We'll rename it to 'Windows Dbl Hung 3'11" Flat Top'.


TH-not-found We need to remove the arch at the top.

Start by drawing a LINE from outside corner to corner as shown.

Don't become alarmed when a surface gets created that covers everything. Just select it and delete it.


TH-not-found We need a surface here, so draw another line from inside corner to corner.


TH-not-found Yes. Like this.


TH-not-found Erase the arc line.


TH-not-found Looks good.

Are we done? Not quite.


TH-not-found ORBIT until your INSIDE the temp building.

We've got to ERASE the arc in here too.


TH-not-found Like this.


TH-not-found Looks good.


TH-not-found Pan back to the Watch Office side of the station.

From the Midpoint of Component of the second floor window next to the Utility Chimney hover, and the drag your mouse down achieving a dotted blue line until your over the bottom of the new 'concrete' stripe.


TH-not-found Then draw a small marker LINE up from the lower edge of the 'stripe' to mark this location.

Do the operation to mark the midpoint of the center window on the stripe.


TH-not-found Drag copies of the double flat windows we created and locate thier tops on the bottom edge of the stripe at the marked locations.


TH-not-found The two marker lines we drew should be ERASED.

Your station side should now look like this.


TH-not-found In this view of the station (after the 1980's when it was converted into a 3-bay station) it shows a double hung window with a flat top on the side of Watch Office. It occupies about 1/3 of the wall space, or 8'/3 = 2' 8".

We will need this window in several more locations as well.


TH-not-found Pan over to the temp building and on the side draw a rectangle 2'8" wide by 6'1" high.


TH-not-found I then selected the interior of the rectangle and PUSHED it in by 4".

Then OFFSET the area 3/4" (.75) creating the window frame box. The I divided it's interior in half.

Then a series of offsets to create our (should be) familiar double hung window.

I've provided the dims here.


TH-not-found PAINT the glass.


TH-not-found Switch to X-ray to ensure your clear behind.

Select the window and Make Component. I named mine 'Window 2'8" x 6'1" Dbl Hung.

Also you should be paying attention to the Glue To: Vertical as well as the CUT OPENING checkbox. ALL our windows are made with THESE settings, or when you place a window it won't make an opening in the wall for it!


TH-not-found And now our model looks this.


Watch this video on YouTube regarding the making of doors and windows. It IS worth your tine.

37. Place six 4' wide flat top windows. Place another 4' window round to on rear. Create a 4' wide 'short' window with arch.
 

TASK: Now that the 'concrete' stripe exists we need to place our 2'8" wide windows. Another 4' window with the brick arch needs to be placed on the rear of the station.

A shorter version of the 4' wide window needs to be created.


TH-not-found Pan to the side of the Watch Office.

Drag a copy of our new 2'8" wide window off the Components Window. This time your going to grab the upper midpoint (or close to it) and then place it at the MIDPOINT of the lower line of the 'concrete' stripe.

Sometimes you do not need a marker line to locate your placement spot if SU already has one for you.


TH-not-found The image from StreetView clearly shows two of our 2'8" windows on the 'street' side of the Watch Office, and three more at the rear corner.


You may wonder why there is no window near the inside left rear corner of the Watch Office. There certainly appears to be the space for one.

If my memory serves me, this 'area' inside station was occupied by the station gongs, bells and registers of the fire alarm telegraph. It also included a 'blackboard' for listing daily 'street closings' and a board listing the stations 'still' boxes, the locations that the companies where 'first due'.


TH-not-found On the Watch Office side I've drawn two GUIDES each 3' in from the corners.

Then I've dragged two copies of the 2'8" windows and placed them at the intersections of the guides and the lower line of the stripe.


TH-not-found This image from StreetView shows the locations of three additional 2'8" windows.


TH-not-found We need three marker lines to indicate where to place these windows.

The two outside I drew by 'hovering down' the bottom 'midpoint of component' location of the windows above.

And the middle marker was determined by the then generated 'midpoint the remaining line.


TH-not-found Then drag off three copies and place the top midpoints as shown.


TH-not-found We need to place another copy of the 4' arched window on the rear of the station.

I've drawn some GUIDES to assist in the location. One referencing the upper line of the side stripe. Another referencing the lower corner of the side windows arch. And the vertical one 5' in from the station edge.

I then drew a LINE on the vertical between the two horizontal guides, to establish a line with a MIDPOINT to draw a marker line.

Now drag a copy of the 4' window onto the station near the desired location.


TH-not-found With the MOVE tool grab the side midpoint of component.


TH-not-found MOVE it to the location shown.

You can ERASE the lines drawn for marking the location.


TH-not-found Your station side now looks like this


TH-not-found The photo show earlier of the station rear corner shows that between the two upper windows is a 'shorter' version of our 4' window with the arch.

We've got one 'inside' a larger assembly. But we also have the window itself not in another assembly. I'll use that one to avoid unneeded object 'ownership' complexities.

Drag a copy of the 4' window with the round top (WITHOUT the brick arch) to the side of the temp building. We'll modify that window.


TH-not-found MAKE IT UNIQUE.


TH-not-found We're going to shorten it up by removing the lower window frame.

I've measured that distance at 3' 9 1/8". Then I added 3/4" because we'll extend a new window frame box along the bottom. That results in 3' 9 7/8". I'll 'call' it 3'10".


TH-not-found Open the Entity Info Window for the object. Let's rename into what it's going to become. I used 'Window 4' x 3'10" w/Rnd Top'.


TH-not-found EDIT the window.

I began by ERASING the offsets and pushes of the lower window panel.


TH-not-found Next DELETE the remaining surface. It will reveal that there are some remaining lines 'behind'. ERASE them also. Zoom in and LOOK carefully for any SMALL little lines left. ERASE them also.


TH-not-found I drew a GUIDE down 3/4" from the bottom edge of the upper window frame, establishing an edge of the new frame bottom.

And then drew a LINE across the GUIDE.


TH-not-found I then began PULLING the new frame across the bottom.


TH-not-found I then ORBITED to complete by PULLing over to the opposite window edge.

I also 'discovered' some of those 'small lines' that did NOT get ERASED, and I erased them also.


TH-not-found I'd like to delete the now unneeded portion of the former window box frame. Selecting and observing though SHOWS clearly that some more defining lines must be drawn as the area that selects IS NOT CORRECT.


TH-not-found One LINE drawn at each corner now shows that the selected area is correct.


TH-not-found Begin ERASING.


TH-not-found And along the bottom also.


TH-not-found Re-draw an edge to create a surface.


TH-not-found PULL that surface out to match the outside surface.


TH-not-found Then ERASE the three remaining lines that made up the outside edges of the former window box frame bottom.

You'll know if you did this correctly by observing the SIZE of the BLUE selecting rectangle surrounding the window after editing. If it remains large you've got something remaining to ERASE.


TH-not-found Drag a copy of the 4' brick arch close to the window.


TH-not-found MOVE accurately the corner of the arch to the corner of the window.


TH-not-found Switch to X-ray to ensure clearance.

Select both the window and the arch and Make Component. I named mine 'Window 4' x 3'10" Rnd Top w/Arch ASSY'.


TH-not-found Now your model looks like this.

38. Place two 4' short windows. Download a 3'0" x 6'8" door and place it. Create a 2'8" window with rounded top and brick arch and place two of them.
 

TASK: We're doing well but still need several more windows created and placed. Also we need to download a door component from the 3D Warehouse.

TH-not-found In order to locate the location to place our new 4" short window I've drawn a LINE between to two 'Midpoint of Components' of the two upper windows in the rear. Then I've drawn a small marker LINE indicating th centerpoint of the horizontal line.

Drag a copy of the 4' short window onto the station side near the marker line.


TH-not-found MOVE the windows top 'Midpoint of Component' into position.

You can then ERASE the horizontal and marker line.


TH-not-found Orbit and Pan to the station rear.

Draw two GUIDES. One horizontal even with the top of the existing windows arch top. And another vertical in 5' from the station edge.


TH-not-found Drag another copy of the 4' short window onto the station rear and place it's top and right side aligned with the guides.


TH-not-found We are going to create a 2'8" window with a rounded top. It also requires a Brick 2'8" Arch. Rather than you creating it (you're more than welcome to try) I've already done it and you can download it from here.


TH-not-found There lots and lots of pre-built components available to you through your Components Window. We require a 3' wide by 6'8" high plain framed door. Let's find one.

Open the Components Window. Click the Drop Down arrow next to the little house icon. Then choose Architecture.


TH-not-found Scroll down a bit and choose DOORS.


TH-not-found Choose page 3, 'Door with Jam, 3-ft' and click it.


TH-not-found Then click 'Download Model', and answer 'Yes'.


TH-not-found After a moment you'll have the door component both on the temp building side, and in your 'members' of your components.

Easy.


TH-not-found Pan/Orbit to the rear of the station.

Draw a LINE (RED axis) across the rear at the base of the first floor level referencing the edge of the level drawn on the side of the station.


TH-not-found Place the door's bottom 'Midpoint of Component' on the marked Midpoint of the horizontal line drawn.


TH-not-found We are now going to modify one of the 2'8" windows with flat tops into one with a rounded top, and an arch.

Drag a copy of that window onto the side of the temp building.


TH-not-found Select it, and make it UNIQUE.


TH-not-found Open the Entity Info and change the Definition Name: into what it will become. I renamed it to 'Window 2'8" x 6'1" Dbl Hung w/Rnd Top'.


TH-not-found EDIT the window, and draw an ARC at the top that has an 8" BULGE.


TH-not-found Orbit a bit to view the bottom of the new arc. PUSH it in by 4", but observe a second surface will show behind the front one.


TH-not-found ERASE the 'front' arcs surface and bottom line. The result should look like this.


TH-not-found Exit editing the window. Select the 2'8" arch. MOVE the arches corner accurately to the corner of the window.


TH-not-found Switch to X-ray to ensure clearance.

Select both the arch and the window, and Make Component. I named mine 'Window 2'8" x 6'1" Dbl Hung Rnd Top w/Arch ASSY'.


TH-not-found Pan/Orbit to the rear of the station.

From the inside edge of the door jam draw a GUIDE 24" away. Do the same on the opposite side of the door.


TH-not-found The door is going to need an arch also. That will come later, but I want to ensure clearance.

From the top 'Midpoint of Component' draw a LINE up (BLUE axis) 20". The 8" for the 'bulge', and 12" for the arch height.


TH-not-found I've drawn some temporary arcs and guides shaping the eventual door arch.

And draw a GUIDE at the height of the 20" line we drew from the door center.

Then drag to copies of our new 2'8" windows with the arch and place them as shown.

I then ERASED the unneeded arcs and guides.


TH-not-found And so far our model now looks like this.

39. Create and Place four 3' doors with an arch. Place several more 4' short windows.
 

TASK: Doors that include a brick arch are required and four need to be placed. Several more 4' short windows require placement.

TH-not-found Our 3' wide doors require a 3'4" wide arch, as the door including it's 2" jam on each side yields a 3'4" space. I've created that arch for you. You can download it here.


TH-not-found Drag a copy of the 3' door onto the temp building side.


TH-not-found Begin tracing the door frame with LINES. Be careful the start at the INSIDE corners of the door jam.


TH-not-found Trace all three edges excluding the top.

Then MOVE the door itself out of the way.


TH-not-found Now draw an ARC on the outline top with an 8" bulge.


TH-not-found Select the area of the outline and PUSH it in by 1 3/4".


TH-not-found Now MOVE the arch and the actual door into position.

But if you observe closely something isn't right. If you select the door area it is 'covered' by another surface. ERASE that surface, and underneath is our door.


TH-not-found But the arc top surface is missing.


TH-not-found EDIT the door. Re-draw an ARC at the top.


TH-not-found Switch to X-ray to ensure your clear.

Select both the doorway and arch, then Make Component. I named mine 'Door 3' Rnd Top w/Brick Arch ASSY'.


TH-not-found Pan/Orbit to the rear of the station.

Drag a copy of the Door/Arch onto the station rear and MOVE it's bottom 'Midpoint of Component' to the Midpoint of the horizontal baseline.


TH-not-found Pan/Orbit to the Fire Escape side of the station.

Draw two GUIDES. One located at the rear end of the left side hand rail of the Upper Landing, and another 2' from that location.


TH-not-found Drag another copy of the Door/Arch and MOVE it into position at the intersection of the second guide and the Upper Landing 'floor'.


TH-not-found Pan to the first floor level. Draw a marker line in from the corner of the concrete base of the escape to the station edge.

Drag another copy of the Door/Arch and place it at that location.

Then ERASE the marker line.


TH-not-found Pan between the octagonal 'towers'. Draw a GUIDE located at the bottom 'Midpoint of Component' of the upper window.

Dtag another copy of the Door/Arch onto the station side near this guideline.


TH-not-found Then MOVE this door to the intersection of the guide and the first floor base.


TH-not-found Pan to the upper level of the escape. Draw two GUIDES. One even with the top of the door arch. And a second aligned tread/riser location of the top step.

Then drag a copy of the 4' short window close to the intersection of these guides.


TH-not-found MOVE the windows top and left edges into alignment with the guides.


TH-not-found Pan to the station rear. Draw GUIDES to mark the edges of the upper windows, and the tops of the lower arches.

Drag two more copies of the 4' short windows into alignment with the guides as shown.


TH-not-found Now our model looks like this...


TH-not-found And like this also.

40. Create and place a Hay Loft door with a brick arch, and an I-beam for the rear of the station.
 

TASK: This station was constructed in 1910. It did not receive any motorized equipment until 1922. While recent photographs show a window in the center of the rear of the station, this area certainly was occupied by a hay loft door to facilitate storage of food and supplies for the horses that would have been stabled in the rear. The original (or at least portions of) I-beam used to hoist goods is still present.

TH-not-found Let's begin the hay loft door by drawing a 8' X 8' RECTANGLE on the side of the temp building.


TH-not-found Divide the rectangle in two vertically. Then OFFSET each side in by 6". Draw a diagonal line corner to corner on each side.

Draw GUIDES parallel to the guides each 3" away.

The photo shows an arc at the top. You may disregard drawing that arc.


TH-not-found Draw LINES along the guides and then ERASE the unneeded lines to establish the diagonal braces.


TH-not-found PUSH in each triangle area 2".


TH-not-found Switch to X-ray to ensure clearance.

Select the doors and Make Component. I named mine 'Hay Loft Doors 8'x8'.


TH-not-found Draw LINES to trace the door outline. Then MOVE the doors out of the way.

Now draw that ARC with an 8" bulge at the top of the outline. Enter 96s to ensure a smooth arc.


TH-not-found ERASE the line across top of the outline.

Select the interior and PUSH it in by 2".


TH-not-found Switch to X-ray to ensure clearance.

Select the outline and Make Component. I named mine 'Hay Loft Door Opening'.


TH-not-found Now MOVE the Doors component into the door opening component. UNGLUE to position it accurately.


TH-not-found Drag a copy of the 8' arch we created earlier onto the area close to the Doors and Opening.


TH-not-found MOVE the corner of the brick arch into position at the corner of the Door Opening.


TH-not-found Switch to X-ray to ensure clearance.

Select both the Doors and the Arch and Make Component. I named mine 'Hay Loft Door w/Brick Arch ASSY'.


TH-not-found In a clear area draw a 12" x 8" RECTANGLE.


TH-not-found I drew some GUIDES and LINES to define an I-beam shape.


TH-not-found Switch to X-ray to ensure clearance.

Select the I-beam shape and Make Component. I named it 'I Beam Shape'.


TH-not-found Pan to the rear of the station. I drew two GUIDES. One 12' up from the bottom of the already placed entrance door. And another down the vertical Mid-line of the station rear.

Drag a copy of our Hay Loft Doors onto the rear and position it's bottom Midpoint of Component at the intersection of the two guides.


TH-not-found I drew an addition GUIDE even with the top of the arches of the already installed windows.

At the intersection of this new guide and the center line drag a copy of the I-beam Shape component and place it's bottom Midpoint of Component at the intersection.


TH-not-found EDIT the I-beam Shape.

It's already an inch thick so PULL out the shape 7'11" to get an 8' I-beam.


TH-not-found Now our model looks like this...


TH-not-found And like this...
