The EAATC Fire Station 3D Modeling Process Illustrated

Part V


 

 

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 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.

  The final UNPAINTED version.

Including window sill extrusions, a center front 4-panel window, flashings over Watch Office roof, lanterns on station front, 3D text over apparatus doors and the app doors themselves, kick plate base extrusions surrounding the base, and door and scuttle hole cover for Hose Tower.

Also the station height off the ground was adjusted, the side entrance steps and door removed. A new side entrance door was added.

41. Create and place window sill extrusions for all windows.
 

TASK: All the windows on the station require a sill extrusion. We'll create them as components and place them.

TH-not-found Before we begin, it's time to save another version of our model file. Mine is revision 10.


TH-not-found Reviewing this former station photo illustrates that the windows on this station include sill extrusions. The are all very similar, except for those on the front which are combined into one extrusion.


TH-not-found This more close-up view clearly shows a sill extrusion.


TH-not-found In order to NOT affect the front windows (yet) make ALL THREE UNIQUE.


TH-not-found Open the Entity Info window and modify the name by adding 'Front' to the assembly name.


TH-not-found You can ERASE the other two and move the renamed one to the center.


TH-not-found Then COPY/MOVE the other two into position.


TH-not-found Pan to the temp building. Draw these three shapes, one each for our 8', 4', and 2'8" window sizes.

They are all dimensioned for reference. \

The PULL each one out by 2".


TH-not-found Switch to X-ray to ensure clearance. Select the 8' sill and Make Component. I named mine 'Window Sill Extrusion 8'.

The do the sane for the other two, changing the dimension at the end to 4' and 2'8" respectively.


TH-not-found Drag a copy of the double 8' with arch window assembly onto the temp building.


TH-not-found EDIT the assembly by double clicking it. Drag off a copy of the 8' sill and position it on the assembly at the corner. Exit editing.

Remember about components... edit one and fix ALL. you should now have a sill extrusion on each every 8' window of the same component name.

Curious? Pan/Orbit around our model and LOOK!


TH-not-found Repeat the process with a 4' window with an arch, and add a 4' sill to it.


TH-not-found And for the 8' windows with the flat top. Use an 8' sill of course.


TH-not-found And the 4' short windows with the arch.


TH-not-found And the 2'8" windows also.


TH-not-found And the 2'8" windows with an arch too.


TH-not-found Don't forget the 8' Hay Loft door too.


TH-not-found If you measure the bottom corner to corner distance of the three front windows you'll (or you should) find it to be 28'.

On the side of the temp building shape a sill for all three. It is the same as the other sills except for it's width.

PULL it out by 2".

I've dimmed for reference.


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

Select the sill and Make Component. I named mine 'Window Sill Extrusion 28'.


TH-not-found Pan to the station front. Drag a copy of the 28' sill below the front windows. Place it accurately at the corners.


TH-not-found EDIT the sill. At the left side of the FIRE STATION logo draw a LINE on the surface of the sill even with that left edge.

Then draw a GUIDE 2" farther left. Draw a LINE following that guide, and then ERASE the first line.

Do the same process for the opposite side.


TH-not-found Now PULL out this 3' area by 18".


TH-not-found Repeat the process with the area above the other side of the FIRE STATION logo.


TH-not-found Your model now looks like this...


TH-not-found And like this also.

42. Create and place the center front 4-panel window.
 

TASK: Older station photos before the 1980's when the station was still a 2-bay as built, shows a double hung window with 4-panels of glass in each frame at the center front of the station. We will create and place that window. You can also download the window here.

TH-not-found Behind Engine 20's 1916 Waterous we can see th center window.


TH-not-found First we need to raise up the sill for the window.

PULL up the bottom surface of the front center of the station to a height of 42".


TH-not-found Then to determine the windows size I drew 3 GUIDES. One down 14", and two each 4" in from each side.

This resulted in a 2'8" x 7'4" overall size.


TH-not-found Pan to the temp building and draw a 7'4" X 2'8" RECTANGLE.


TH-not-found PUSH the interior in by 4". Then OFFSET it by .75" to create the window box frame.

Then horizontally divide it by drawing a LINE from midpoint to midpoint.


TH-not-found Next for EACH window frame create OFFSETS OF (the .75" is already done) 2", 3/4" and 3/8".

Then I drew GUIDES. First one each dividing the 'glass' area in half horizontally and vertically. Next another four GUIDES each 3/16" from the horiz and vert guides, defining the 'moulding's' to hold the four glass segments.


TH-not-found Then I drew LINES following the outside guides, and ERASED the unneeded lines to create the frames for all window portions.

I temporarily colored the 'glass moulding's' for reference. Your's should look like this.


TH-not-found Now a series of PUSH'S like identical to all the other windows we've created. You should be getting good with this by now.

PAINT the glass also.


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

Select the window and Make Component. I named mine ' Window 2'8" x 7'4" Dbl Hung 4-Panel'. You can download it here if you need.


TH-not-found Pan to the station front. Drag a copy of the new window into it's position and MOVE it's corner into place.


TH-not-found You may now ERASE the two unneeded vertical lines below the sill.


TH-not-found The model looks like this.

43. Position a door and a window for the entrance near the Watch Office. Add an additional railing on the steps hand railing.
 

TASK: A door and it's window needs to installed at the entrance near the Watch Office. An additional railing we neglected to create previously needs to be created in installed.

TH-not-found A door needs to installed here, however the current height of the steps landing is three inches below the first floor level.

I drew a GUIDE on the wall showing the height difference. And another GUIDE showing the tread depth of a new step we'll create here.


TH-not-found Draw a LINE along the 11" guide.

Then PULL up the new step 3".


TH-not-found Drag a copy of the 3' door onto the midpoint of the new step.


TH-not-found Make the door UNIQUE.


TH-not-found EDIT the door component.

ERASE the arc over the door.

Exit editing the door.


TH-not-found Switch to X-ray. Careful, this it tricky.

You want to locate the line at the center of the upper handrail we created previously.

From that point draw a LINE down (BLUE axis) to the top of the new step.


TH-not-found Locate the midpoint of that line.

Draw a 1" radius CIRCLE at that point.


TH-not-found ERASE the vertical line, including the interior of the circle.

Then draw a LINE from the circle center on the RED axis and continue it to the line in the center of the vertical post of the previously created railing. Look carefully!


TH-not-found Then continue another LINE from that point to the midpoint of the vertical line inside the next post of the hand rail.


TH-not-found Then select and shift/select until the full set of lines are SELECTED.

Then FOLLOW ME on the circle.


TH-not-found Your result should be close to this.

A little PULLING is needed to complete the process.


TH-not-found Make your's look close to this.


TH-not-found Pan to the temp building.

Draw a 3'4" x 3'4" (square) RECTANGLE.


TH-not-found Create an OFFSET of 2". Then another of 1".

Then PULL out the 2" offset by 3/4". PUSH in the second offset 3/4". And then the 'glass' interior 1/2".


TH-not-found PAINT the interior 'glass'.


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

Select the window, and Make Component. I named mine 'Window 3'4" x 3'4" Over Door.


TH-not-found Pan back to the station side.

Drag a copy of our new window near the door top.


TH-not-found MOVE the window into correct position.


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

44. Create roof flashing's for the Watch Office roof. Create and place the lanterns for the station front.
 

TASK: The sides of the small roofs of the Watch Office require some flashing. The station front requires a pair of lanterns. We'll create these items and place them.

TH-not-found Looking carefully you will see an amount of 'flashing' at the sides of the roof area. We'll create and place that flashing.


TH-not-found Draw a short 3" LINE up from the inside corner of the roof.

The draw LINES, beginning at this 3" point, PARALLEL to the roof edges as shown. Draw any lines needed in order to be able to select the flashing area.


TH-not-found Draw a short 3" LINE up from the inside corner of the roof.

The draw LINES, beginning at this 3" point, PARALLEL to the roof edges as shown. Draw any lines needed in order to be able to select the flashing area.


TH-not-found Repeat the process for the opposite side's roof.


TH-not-found We've got a small problem to fix.

Notice that when I click just on the station front at the same level as the 'concrete stipe' the WHOLE of the upper front gets selected.

This is NOT what I desire. I want just an area the same height as the stripe to be selected on the front.


TH-not-found Beginning at the upper corner of the stripe draw a LINE across the whole station front on the RED axis, to it's opposite corner.

Now the proper area gets selected.


TH-not-found In this old photograph of the station just above the shoulders of Chief of Department Strapp and the portly Captain of the engine, you'll notice a pair of lanterns on the front station wall.

We'll create and place those lanterns. Or, you can download them here.


TH-not-found Pan to the temp building.

Draw a 12" high by 6" wide rectangle.


TH-not-found Pull that rectangle out 1".

Then draw 2" x 2" rectangle in the center. Next PULL that 2 x 2 rectangle out 6".


TH-not-found Draw a 10" x 10" x 2" rectangular centered on the end of the 2" 'post'.

Observe the dimensioned drawing.


TH-not-found Draw two X'ed lines to determine the center point.

Then draw 1 1/2" radius circle in the center.


TH-not-found ERASE the unneeded lines and PULL the circle up 2".

At the center top (remember Arc Centerpoint) draw a 1 1/8" radius circle. The PULL that circle up 1".


TH-not-found From the centerpoint of the circle draw a LINE up 8" on the BLUE axis.

Then from the center of the circle draw a LINE out to the circles circumference. This gives you two edges of a vertical rectangle. Complete that rectangle.

You now have a place on which to draw the profile shown.


TH-not-found Draw a LINE in 3/16" and a small ARC to ease the corner.


TH-not-found ERASE any unneeded lines to achieve your profile shape (half of a light bulb).

Select the circle at the base of the 'bulb'. Then FOLLOW ME the shape.


TH-not-found The result is a 'bulb'.


TH-not-found Pan/Orbit so your underneath ledge.

Draw a 1 1/2" circle in the center. PULL that circle down 1".

The from the circles center draw a LINE down 8" on the BLUE axis. Complete a rectangle upon which to draw a profile.


TH-not-found Draw a raw profile similar to this.


TH-not-found ERASE unneeded lines to create your shape.

Select the circle, then FOLLOW ME your shape.


TH-not-found The result will be the lower extrusion.


TH-not-found Pan/Orbit to see the top of the ledge.

COPY/PULL (ctrl key) a NEW surface up 12".


TH-not-found DELETE the top surface. When you pulled that new surface up it also pulled up the inner circle.

You can ERASE that 'circle', as shown.


TH-not-found Re-draw an edge to re-create the top surface.

Then OFFSET that surface out 2".


TH-not-found PULL that offset surface up 2".


TH-not-found ERASE the vertical edges of the 12" 'box' surrounding the light bulb area. You'll be left then with just the two 'ledges'.

Then draw four LINES as shown 'outside-to-inside' to create a pyramid shape.


TH-not-found Then OFFSET each of these new side by 1/2".

Then PUSH in the inside surface 1/4".

These are the areas of the four 'glass' panels.


TH-not-found You can PAINT the panels glass.


TH-not-found Draw diagonals across the open center. Then draw a CIRCLE to fit the inner surface.


TH-not-found ERASE unneeded lines. PULL the circle up 1/2".

Draw a LINE up in the BLUE axis 4".


TH-not-found You desire to create a 'rounded' top for the upper extrusion.

I did this shape details for mine.


TH-not-found ERASE unneeded lines to make your shape. Select it to ensure it's 'okay'.

Select the circle SURFACE... Then FOLLOW ME on your shape.


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

Select the Lantern and Make Component. I named mine 'Front Lantern Stn 14b'.


TH-not-found I drew some temporary LINES on the station front to establish the center of the two sides opposite the center window. Make your installation point 7' up from the base.

Drag a copy of the Lantern onto the station side. It most likely will be disoriented.


TH-not-found Use the ROTATE tool, and rotate the lantern attachment rectangle on the RED axis 90 degrees.


TH-not-found MOVE the lower Midpoint of Component of the attachment to the end point of the 7' center marking line.


TH-not-found Now COPY/MOVE the Lantern to the opposite side of the center front.


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

45. Create and place the over apparatus door 3D recessed text.
 

TASK: Over each apparatus door there is 3D recessed text naming the companies assigned to this station. We will create and place that text.

TH-not-found This older photo of the station shows that over each apparatus door there was 3D recessed text naming the companies assigned to the station.

It read 'H. & L. Co. No 10' and 'Engine Co. No 20'. Although the 'No' text had an underline under the lower case 'o'. We'll have to deal with that.

Recall that this station built in 1910 as Station 20 did not become Station 14 until 1922.


TH-not-found Pan to the temp building. Open the 3D text tool.

Just as we did for the FIRE STATION logo we'll use DejaVu Serif Condensed. 1' high, -1" extruded, Centered. I'll use the '' symbol to indicate the 'space' character.

I entered this...
H.[space] &[space]L. [space]Co. [space]N [space][space]10 [space][space]o [space]-

The extra space after the 'N' is so that we'll have room to insert the 'o with an underline' there. And the 'o' and '-' at the end are to create them.


TH-not-found Place that text. Then EXPLODE it.


TH-not-found Open the 3D text tool again.

I entered...
ENGINE[space] Co.[space] N[space][space] 20

While the picture shows an 'o' and '-' we'll not need the extra ones.

Place that text and EXPLODE it also.


TH-not-found Next I selected each and every (shift select) letter surface. Then I right clicked and chose ERASE.


TH-not-found Which gave me this.


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

Select the H. &. L Co. N 10'. DON'T select the 'o -'. Make Component.

I named mine 'H & L Co 3D text'.


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

Select the ENGINE Co. N 20'. DON'T select the 'o -'. Make Component.

I named mine 'Engine Co 3D text'.


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

Select the just the little 'o'. Make Component.

I named mine 'O lower case 3D text'.


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

Select the just the '-'. Make Component.

I named mine 'Dash 3D text'.


TH-not-found Now MOVE the Dash to right under the little 'o'.


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

Select the 'o -'. Make Component.

I named mine 'O w/Dash Under 3D text'.


TH-not-found MOVE the 'o-' next to the 'N' in H&L text.


TH-not-found Drag another copy of the 'o-' onto the texts'.

MOVE the 'o-' next to the 'N' in ENGINE text.


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

Select the whole ladder text. Make Component.

I named mine 'H & L Co No 10 3D text ASSY'.


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

Select the whole engine text. Make Component.

I named mine 'Engine Co No 20 3D text ASSY'.


TH-not-found We need to determine the centerpoint over the apparatus doors.

Pan to the left side of the left apparatus door.

Draw a short line as shown.


TH-not-found Do the same at the right side of the left door.

This has now established a centerpoint over the door.


TH-not-found The area over the app doors is 18" high. Our 3D text is 12" high.

So at the centerpoint draw a marker LINE up 3".


TH-not-found Drag a copy of the 'ladder' text onto the above apparatus door area.


TH-not-found Locate (if you can) the bottom Midpoint of Component of the text (right below the 'C') and MOVE it to the end of the marker line.

Repeat the same process with the 'Engine' text.

You can ERASE the marker line and the 'end' lines drawn also.


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

46. Alter station height off the ground. Remove side steps and alter door.
 

TASK: Historical research has led to needs for alteration of the station's 'height' off the ground. Some modification of other building components, such as the side step way are required also.

TH-not-found In this station photograph circa 1980's (Squad 2 is in the picture), it is clear that there is a distinct taper down in height from right to left at the station front.

Also it is clear looking at the Watch Office area that a number of the stations basement foundation cinder blocks are visible.

Also surrounding the station is 'kick-plate' extrusion. The extrusion is several feet above ground on the building sides.


TH-not-found In this 'current' view of the station rear shows again the 'kick-plate' extrusion several feet off the ground. Such kick-plates were always constructed at the ground level, not elevated.


TH-not-found Observe in this much older photo of the station paying particular attention to the levels at the base of the apparatus doors. No change in level is noticeable, unlike more 'modern' station photos. Also it appears that the station apparatus drive was made of paving bricks.


It is now apparent that the station was not paved as more modern photos illustrate. The station fronts on Snelling Avenue, also known as Minnesota State Highway 51. Highway 51 was not paved until 1936, more than 25 years after the stations construction. Ashland Avenue on the south station side was certainly not paved yet at station construction.

My conclusion is that those level changes observable in modern station photos, were not present when the station was built. They occurred due to later paving of the surrounding streets. I am going to model, as always, 'as constructed'. We are going to change the stations level above ground.


TH-not-found This would be an EXCELLENT time to have a backup of what the model was like before we make such a major change.

My new version will be #11.


TH-not-found Pan/Orbit to the Watch Office corner of the station.

Draw a GUIDE 2' up on the side of the station.


TH-not-found Pan/Orbit so your under the station.

Click to select the station bottom. Notice not all of the bottom selects. The Utility Chimney and the Watch Office bottom's don't get selected.


TH-not-found Orbit and draw a LINE to complete and separate the Watch Office side and the base of the stairs.


TH-not-found ERASE the lines separating the chimney and Watch Office from the rest of the station bottom.


TH-not-found Now select the bottom. You should get like this. I've colored mine temporarily yellow for reference.

It should NOT include the stairs bottom.


TH-not-found PUSH the whole selected bottom of the station up by 2' to match the GUIDE drawn, and the front and Tower side level extensions.


TH-not-found When you release your mouse button the bottom will disappear. Not to worry.

Re-draw the station side edge on the Tower side as shown.


TH-not-found The bottom will be re-created.


TH-not-found Pan/Orbit to the stairway.

Begin carefully ERASING the lines of the stairway.


TH-not-found Continue ERASING the lines of the stairway.


TH-not-found Orbit/Pan so your clear. Select as much as you can of the hand rails. Be CAREFUL!

Then ERASE. Remember UNDO if you need to.


TH-not-found Continue ERASING until all that's left are the two circles on the side next to the door.


TH-not-found Switch to X-ray. Pan/Orbit until there is nothing 'behind' the two circles.

Select the circles. ERASE them.


TH-not-found Select the door and the window above.

ERASE them. Draw a small marker line down from the centerpoint of the bottom edge.

Drag a copy of out door with the arch onto the building side.


TH-not-found MOVE the doors bottom Midpoint of Component the marker line.


TH-not-found Divide the front level extension in half by drawing a line from the left edge centerpoint.


TH-not-found Divide the side level extension in half by drawing a line from the rear edge centerpoint.


TH-not-found ERASE the outside portions.


TH-not-found Pan/Orbit to the Watch Office corner of the station.

Notice that th whole station is now 2' above the ORIGIN of the red/green/blue axis.


TH-not-found Zoom out and select the whole station.

Be careful anything you do at this point will affect the entire station (including erase!).


TH-not-found Pan/Orbit to the lower corner.

MOVE it down to the ORIGIN.


TH-not-found Our model now looks like this.

47a. Create the apparatus door frame, the 'inside' door shape, and the lower door section.
 

TASK: Size the app door and create it's frame. Create the door shape, and create the lower door section.

TH-not-found This is the only photo that includes a partial view of the original apparatus doors that we are aware of.

Viewable are the two upper sections. At the top a series of segmented panels, and in the center a six or nine (it's unclear) window panel section. I'll choose the nine panel choice.

For the lower panel it's a 'modelers choice', but based on several other similar apparatus doors, and a 'carpenters preference' I will make it a crossed brace section for door 'strength'.


TH-not-found Our door areas are identical (they should be). They are both 12' high by 10' wide.

First we need a door frame.


TH-not-found Our door areas are identical (they should be). They are both 12' high by 10' wide.

First we need a door frame.


TH-not-found All of our apparatus door construction will take place on the temp building.

Draw a 12' by 10' RECTANGLE.


TH-not-found OFFSET in 4".


TH-not-found Draw a LINE down at each corner. Then ERASE the bottom line of the offset.


TH-not-found PULL the outside of the frame out 2".


TH-not-found PUSH the inside of the frame in 2".


TH-not-found Switch to X-ray and zoom/orbit to ensure clearance. Select the door frame and Make Component.

I named mine 'App Door Frame'.


TH-not-found The interior of the door frame, which is the SIZE of our doors, is 11'8" high by 9'4" wide.


TH-not-found Pan to a clear area.

Draw an 11'8" by 9'4" RECTANGLE.

I dimmed mine for reference. Be sure these dimensions MATCH the interior of the frame.


TH-not-found OFFSET this rectangle IN by 6".

Next DIVIDE the side of the interior offset into 3 equal segments.


TH-not-found Draw a LINE down the complete area dividing the rectangle into two 'doors'.

Draw two vertical GUIDES each 6" away from this vertical centerline. Draw two LINES following these guides INSIDE the offset.

Now two horizontal GUIDES each from the division points we drew earlier. Then 4 GUIDES each 3" from these horizontal's, forming two 6" spaces.

Draw 4 LINES across the 3" guides.


TH-not-found Turning off the guides, and ERASING the unneeded lines, you should have two doors, each with 3 equal areas.

The segments will be placed in the top, glass in the middle, and frame work in the lower.

And ALL portions should have a 6" border frame.


TH-not-found In the lower section of both sides divide each by drawing LINES from centerpoints in both vert and horiz directions.

Then GUIDES each 3" away from these lines forming 6" wide spaces.

Then two diagonal lines as shown, and GUIDES each 3" from the diagonals.


TH-not-found Draw LINES in the lower section following all the guides, resulting in this.


TH-not-found ERASE the unneeded lines, and then insure each 'side' selects properly, like this.


TH-not-found Now PUSH in each section by 1.5".


Good job... but we've still got more to do.

 
Return to Top

47b. Create the center 'glass' section.
 

TASK: In the center of the doors there are two 9-panel glass sections. We'll create them now.

TH-not-found In each of the two center sections OFFSET them both IN by 1".


TH-not-found In the INTERIOR of each offset DIVIDE the sides and tops into 3 equal segments.


TH-not-found Then draw GUIDES at all of these divided locations.


TH-not-found Now a GUIDE 1/2" away from each one just drawn.


TH-not-found Draw LINES following each outside guide. Like this.


TH-not-found ERASE the unneeded lines and ensure the glass frames select properly. I temporarily colored mine yellow for reference.


TH-not-found PUSH in the frame 1.5".

Repeat on the other side.


TH-not-found PUSH in each glass area to match.

Repeat on the other side.


TH-not-found Your should look like this.


TH-not-found Now PUSH in each glass area by 1/2".


TH-not-found The result should be this.


TH-not-found PAINT each section with 'glass'.


TH-not-found This is our results so far.

none
47c. Create the top segmented section.
 

TASK: The top segmeted section is made from 11 'boards' each tapered. With components and copy/move it's easy to create.

TH-not-found The upper sections are each 3'8" (44") wide. The height value is not really important as long as we match it.

I drew two GUIDES to match the height, and then a rectangular 'object' to match the upper section.


TH-not-found At the top corner draw a 4" LINE in to measure, and then complete a small rectangle.


TH-not-found PULL the rectangle out 4".

Then on both outside corners draw 1/4" lines in to measure. Then draw two LINES along the top to the rear corners as shown.


TH-not-found PUSH the triangular area down all the way. It should completely disappear.

Do the same for the other side also.


TH-not-found Switch to X-ray to ensure clearance. Select the rectangle and Make Component.

I named mine 'App Door Upper Segment part'.


TH-not-found Select the Segment part. Then COPY/MOVE it so it's exactly next to it's neighbor part...


TH-not-found Enter 10x.

Now we've got 11 tapered (short) 'boards'.


TH-not-found Select the 'first' board. EDIT it.

Orbit/Pan to view underneath the rectangle. PULL the lower surface down to match the upper surface bottom distance.

All 11 boards will match.


TH-not-found Select the 'left' board. Make it UNIQUE.


TH-not-found We want to 'remove' the taper on each outside board.

Using SU's inferencing begin redrawing the upper corner. Complete the corner.


TH-not-found Then from the outside corner draw a LINE on BLUE axis all the way down to begin the 'long' part of the new side.


TH-not-found Complete the corner. Your previous taper should be 'gone'.


TH-not-found You should now ERASE the former lines of the taper.


TH-not-found Exit editing the left board.

Select the 'right' board. Make it UNIQUE.

Repeat the 'taper removal' on the outside edge of the board.


TH-not-found Exit editing the left board.

Switch to X-ray to ensure clearance. Select our set of 'boards', and Make Component.

I named mine 'App Door Upper Segmented whole'.


TH-not-found Pan to the set of doors. EDIT it.

49. Create and place a door on the Hose Tower rear, and create and place a roof scuttle hole cover. Add a sloped surface to the Chimney.
 

TASK: The Hose Tower requires an access door, and the roof requires a scuttle access hole cover. We'll create and place both. The Chimney needs a few more 'bricks'.

These should be the FINAL three pieces of construction required for this model. We are NOT done yet, but the hard stuff is DONE.


TH-not-found Close observation of this photo shows an access door on the rear of the Hose Tower.

This makes perfect sense, as access to the top of tower would be normal in order perform the then required drying of cotton jacketed fire hose.

A way to get on the roof (a scuttle hole) would also be needed.


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


TH-not-found Select the Tower.


TH-not-found Remember it is not unusual for components to be nested. You must select deep enough to get to the portion you desire.

Double click the Tower. Then double the Tower section itself.


TH-not-found Now your deep enough to edit the Tower in order to make room for a door.


TH-not-found We need to remove section of the brick extension.

I've turned on 'Hidden Geometry' to assist. I've drawn LINES from the inside to outside corners, and LINES down the outside surface.


TH-not-found And LINES below so that we have isolated the section to be removed.


TH-not-found Now ERASE the lines that form the section.


TH-not-found REVERSE the surface of the now open end of the brick extension.

Repeat the process on the opposite side.


TH-not-found Dimensions show we have 7' (plus) high by 3' (plus) wide space for a door.


TH-not-found Pan to the temp building.

Draw a RECTANGLE 6'10" x 2'10".


TH-not-found I then drew 3 GUIDES, two IN from the sides, and one DOWN from the top, all of 2". These form the jams of the door.

Then draw three LINES to define the 2'6" by 6'8" space.


TH-not-found PULL the frame out 1".


TH-not-found PUSH the 'door' in by 1/2".


TH-not-found We're going to place a door knob 36" above the bottom edge of the door.

Draw a GUIDE at 36".


TH-not-found Open the Components Window. Choose DOORS. The 3D warehouse will open. Choose page 2.

Then choose 'Doorknob Octagonal'.


TH-not-found The Doorknob's window will open.

Click 'Download Model', and then 'YES'.


TH-not-found MOVE the doorknob component into position.


TH-not-found Switch to X-ray to ensure clearance. Select the door and frame and Make Component.

I named mine 'Door w/Jam 2'6 x 6'8'.


TH-not-found Re-edit the Tower. Be sure you go 'deep' enough.

Drag a copy of our new door onto the surface.


TH-not-found MOVE it into position at the center bottom.


TH-not-found Exit editing. Our Tower now looks like this.


TH-not-found Draw a GUIDE 15' in from the roof edge.

The draw a 4' LINE on the guide on the roof surface.


TH-not-found Draw a 2" LINE up (BLUE axis) on the forward edge.

Remember we are a sloping surface (remember our sloped roof). Now draw a LINE from the top of the 2" line just drawn, and the hover over the opposite end of the 4' line. Allow SU's inferencing to assist in completing the line on the GREEN axis .

Then complete the 'box'. I dimmed it to show the difference in size. The top edge should be parallel to the 'ground'.


TH-not-found Draw LINES to complete a box 2" high at the front. Let SU inference to assist in the completion.


TH-not-found Retrace an edge to complete te top surface.

OFFSET the top surface OUT 1".

Then PULL the offset area up 2".


TH-not-found Draw a diagonal to complete the new top surface.

ERASE the unneeded lines.


TH-not-found Switch to X-ray and then pan/orbit to ENSURE your 'over' the station floor and clear.

Select the new scuttle cover and Make Component.

I named mine 'Roof Scuttle Cover'. Glue It to Horizontal.


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

Draw 4 GUIDES. Three each 4" in, and one 3 feet up.


TH-not-found Draw a LINE across the 3 foot guide, and two down on the diagonals.

Finally draw and complete a LINE on the flat outside guide. The completed sloping new 'brick' surfaces should be complete.


TH-not-found Here's our modified roof.

50. Complete the final INSPECTION.
     Save and take 'photos' of the FINAL UNPAINTED model version.
 

TASK: Start and complete the INSPECTION process, and the save the final 'UNPAINTED' version of the model file.



We have finally reached a true milestone. The bricklayers have packed up their mortar boards and trowels. The plumbers and electricians packed up also. Everybody's horses and carts have arrived, been loaded, and departed.

This a public building and tax funded. Now a fancy 4-horse black cart has arrived emblazoned with a City Inspectors Seal. Off steps the Inspector, whose job is to look at EVERYTHING and make any final changes to the structure before the arrival of the 'painting and wallpapers'.




The INSPECTION process:

The inspection process does not actually have a step-by-step sequence. It is really a very detailed 'looking around' to find any final changes to be 'cosmetically' to the building and it's components.

We're looking for any 'extra unneeded' lines that can either be ERASED or HIDDEN before we commit this model to the final PAINTING process.

Unfortunately there is no substitute for experience, but a dedicated desire to produce a good product will go a long way to assist. I typically spend at least 3 hours of inspection time on ANY station I produce. On this station I discovered over 200 minor changes to be made. These changes did not alter the construction shape of any objects in the model, but rather they affected the way those objects will appear in the final model.

Here is a list of what to look for and perform:
  • Be prepared to Zoom/Pan/Orbit in on everything in detail
  • Select ALL surfaces one by one and ensure they respond ad you expect. What gets selected, gets painted.
  • Zoom in on any component that was produced with a PROFILE, and ERASE the profile lines left over.
  • When EVER you erase, check THEN to ensure only what you erased has been affected. UNDO if required.
  • Your erasing in order to REDUCE the number of surfaces that require the painting process.
  • Often you cannot erase without affecting something else. This is the time the time to HIDE lines.
  • Afraid that hiding lines makes them impossible to find again. Not to worry, just switch on Hidden Geometry.
  • Look at everything zoomed way in and orbit. You'll be surprised what you'll discover.
  • Think your done? Nope, look further. Then DO IT AGAIN!
  • Once you've produced the final version, the one the world sees, you'll discover something that you wished you would have fixed. It happens to me, it WILL happen to you!


The UNPAINTED version:

Experience has proven to me that if I ever desired to make structural changes to a model, it is far easier to do it on the final unpainted version rather than the true final one on which everything has been colored, including ALL the defined components.

It is desirable to have a 'clean' version of the model.

But you may think ours is NOT unpainted. We painted the 'glass' surfaces, and the meshwork on the Fire Escape. True, but I consider those 'paintings' as more structural rather than beautification.



TH-not-found If your inspection is complete (is it?) then it is time to save the final version of the unpainted version of our model.

I named mine 'St_Paul_Former_1910_Station_14b_v12_unpainted.skp'. Notice the version and additional 'unpainted' I added.

We will no longer edit this version, but in the next segment the first thing we'll do is save it to the FINAL (yes the real final) version.


TH-not-found It's time to save final pictures of this version. Arrange the view to one you like.

Then choose File/Export/2D Graphic...


TH-not-found You'll be presented with a directory chooser. Navigate to the directory you wish to save your model photos in.

Chosse Exort Type: .jpg. Add '_01' to the end of the filename...


TH-not-found If you choose Options you'll be presented with a dialog similar to this. You probably need not change anything. Click Cancel.

Click Save.

After a few moments the image will save.


TH-not-found Change the models positioning. Repeat the process with another 2D image.

Remember to rename to an _02 picture version.


TH-not-found I usually CROP these saved images to reduce their size.

I never use Windows Paint (the default image editor) to do my image editing. You may have PhotoShop, or PaintShop, or some other editor. Use the one of your choice. We Windows users ALL have Paint. For Mac users you may have GIMP or Sketchbook Express. I'll use Paint for my examples.

Open Paint. Chose File/Open. Navigate to where you saved your pictures. Choose the 01 version, and Open.


TH-not-found In Paint draw a SELECTION box around a smaller portion of the image. Then choose CROP.


TH-not-found Your image will then look simiar to this.


TH-not-found We must save our changes. Choose SAVE AS. You'll be asked if you want to over write the current saved file. Click YES.

Repeat the process with the other versions of your saved model pictures.


TH-not-found The FINAL UNPAINTED version of our model looks like this...


TH-not-found And like this!!!

Congratulations!
