My upper level city design is progressing. Now I know why I am not a city planner.

CITY OVERALL 2

CITY CLOSE

The City Model is in CorelDraw. The drawing is done in actual size of the 1/4 scale city. Once compete I will use it to make Laser Cuts of the streets and sidewalks then reassemble in to the whole city.

The Woodland and Menards buildings, cars and sewer grates provide guides and orientation  to making and cutting the streets and sidewalks.

CITY CHOPPED

My upper level city roadways and sidewalks looks like this in laser cut grid. What is shown above is the laser cut squares. Each square will be laser cut and fits together like a puzzle on the supporting surface. I did modify the building locations from what is shown on the earlier thread above.

So the way this is done on CorelDraw (or any other graphics program) is to create a movable window the size that the laser cutter can cut. Then remove all details outside the window, leaving the parts within the window to send to the laser cutter.

CITY CHOPPED D3

The above is grid square D3



D3

The above square D3  is converted to a .svg file that my GlowForge laser cutter will cut.

the black lines shown are scored for sidewalk joints and the red lines are the curb cuts and storm sewer grates openings.

This looks more complicated than it really is. The process is fairly straight forward.

Also I have the AUTOMOTIONFX paths for my Automotionfx cars designed.

I will laser-ENGRAVE these paths on the reverse side of the roadways to fit the magnetic/iron rods that will be placed into the engraved paths underneath. So to do this I will take my laser square designs and MIRROR them to detail the underside engravings.



I believe that AutomotionFX uses a GlowForge to create their roadways, since their roadways are made from GF 1/8" draft board.

This Grid-Window Method can be used to laser cut much larger objects than the laser cutter bed size supports.

Super streets is limited to the street track pieces. AutomotiveFX  unlike the HO version of it used in Europe is also limited to their track pieces.

However, when I laser cut and engrave my own track pieces there is no limitation, except as to the turning radius and size dimensions of the specific AutomotiveFX car or bus or truck so equipped.

I purchased several switch-tracks from AutomotiveFX to incorporate into the paths; like going into and out-of the gas stations.

city all layer

All layers on this view; the image is separated into several layers to facilitate cutting; a street layer and a curb and sidewalk layer.

The street will be laser cut from 1/8" draft board like MDF, the curbs and sidewalks from 1/4" draft board; the curbs will be then routed for a curved edge to the street.

The street and curbs will have cut-outs to fit the 3D printed sewer grates and sewer covers. The street markings and walkway marks will be cut out and replaced with colored acrylic shapes in white and yellow.

city all layers w FX

City all layers shown. To laser cut I separated the elements into layers. the streets layer is 1/8" thick draft board shown below.

as stated above the layers are separated into rectangular Panels to be laser cut. The black lines shown below are scored the red lines are cuts.

All of the street markings are cut. these cuts are filled with yellow and white acrylic to represent the street marking colors. Sizes of markings are scaled per New York Highway Department Street mark standards.

the other sewers and street manholes are filled with 3D laser printed sewer covers and storm grates shown in other threads.

the exact size of the cuts comes from a .DXF image of the top view of the 3D model in Rhino 7 superimposed into as a 2D image into Corel Draw.

the streets and sidewalks painted concrete gray.



city streets only

Sidewalk layer is cut from 1/4" thick draft board

city sildwalks only

Automotion FX paths, these paths are for the magnetic wires. the paths are laser engravings engraved in the UNDERSIDE of each panel.

to engrave, the image below is mirrored, and the reverse side of the panel is engraved with the wiring engrave path. Each panel will have its associated wire(s) installed so that when all the street panels are all in place the Automotion FX wire paths will connect.

I have several Automotion FX switches that will be used to re-direct the cars in different paths as well as into (and out of) each gas station shown below.

3D printed Street sign designs



street signs

These street signs will either be on or connect to hollow brass tubes or attached around traffic signals.

The top and bottom designs shown hide tiny LEDs that will shine down and up onto the letters.

The letters shown are 3D printed with the sign frame, however they may be CLEAR acrylic engraved to better reflect the LEDs.

the next step is to layout sidewalk streetlights, traffic signals, tree grates hydrants,  street name signs (above) etc for the insertion holes to be laser cut.

Alan, Those are great looking. Your continued innovation is really impressive.

Hydrants with chains printed as a group.

I use the supports to hold the hydrants in place for painting.

there is a stem below to insert into sidewalks.







Close up. Actual height is 0.73" or 32" (1/48) scale.

chains attached to the three covers are discernable as links; note bolting.



Alan, Your hydrants and postal boxes look better than any I've seen printed.
