The result city model has all roads blank, meaning they don’t show in the final output for print. Is it because they are flat? What can I do to have them show with the onlime version of SkethUp?
Is this the right format to post here?
Thanks.

How are you trying to print this? If you are intended to 3D print it, no, the roads and the rest of the edges on the surfaces will not show. You need variations in the surface in order for them to show. The terrain isn’t ready for 3D printing anyway because it isn’t a solid object. In addition to creating elevation differences on the surface you would need to make the terrain a solid group in order for it to be 3D printable.
What version of SketchUp are you really using? There is no Classic license for SketchUp 2025 Desktop. Please correct your profile.
My free trial is ending. So ot’s the free version online now.
The model does print in 3D. I opened the 3D file into online Sketchup to change the file format to STL, , then to Fusion 360 to change it to MF3. The 3D print works.
How do I do this in the free onlime version?
“: In addition to creating elevation differences on the surface you would need to make the terrain a solid group in order for it to be 3D printable.”
I wondered if I should try to raise the roads a bit. I saw roads on another’s result, but not sure how he did it.
Thanks.
How do you do what in the free online version?
You would need to do that. The 3D printed isn’t printing edges. They have no thickness. The faces in the model define the interface between the print media and air. The back faces in the SketchUp model are toward the print media while the front faces are toward air.
What does the terrain look like? In the SketchUp model theres no thickness in the terrain so nothing to print. Perhaps you are adding thickness in F360.
On second look, yes, I need to add a thickness on the terrain.Can be done in Fusion. Easy in SketchUp online?
As for help, I was quoting on how to do this " In addition to creating elevation differences on the surface you would need to make the terrain a solid group in order for it to be 3D printable.”
That is, how do I raise the roads online?
Thanks.
For flat faces you can edit the group and use Push/Pull. It won’t work on surfaces, especially ones that aren’t flat. It will be time consuming but I guess you are doing this as a hobby so you can just look at it as part of the process.
There are extensions that can make the process easier but you would need to be using SketchUp for Desktop which requires a Pro or Studio subscription.
Darn it.
How can you do raise roads with the license version and extensions?
Extensions like Joint Push/Pull can be used to raise or lower surfaces. You might also use the Sandbox Tools Stamp function. There are a number of ways.
Before you do anything in your model you will need to do a bit of cleanup to get rid of unneeded edges.
Is it possible to download just the roads from the online version? Seems not.
Delete the rest of the geometry leaving only the roads and then you can download only the remaining geometry.
My thought is to increase the height of the roads-only file, then export that file into the original map, oriented so the 2 merge with higher roads. Make sense?
I really don’t know what you are after and why you are trying to make a 3D printed model of thios thing but if it makes sense to you, go for it. I have to assume since you are using the free web version that you are doing this for your own entertainment.
I have an original model with roads flat, and thus don’t show in a 3D print. So, the thought is, save a roads-only model from the original model. In the roads model, increase the height/thickness.Then combine that roads model back into the original, flat road model. That would give a final model with raised/thickened roads.
