Quick tutorial for road design on a terrain

Pete, Csaba, Pilou,

please can you show me an example how you would do this on the Test Road.skp above.

For that, I'd need the mesh as it is now AND the road that you integrated in that other app (which I don't know) separately imported into SU.

Can you rip the road only, somehow like Pete suggested above? It would be a long, thin strip this way.

In theory you can draw your road with "Tools on surface" by Fredo6 on top view
Just hide or separate some useless reliefs around the road for have a speedy calculate

Hi Csaba,

the road was generated with Geocontrol (GC). The workflow is as follows:

Generation of a terrain
Drawing the road direction by a Vector tool on a 2D height shaded view
Road will be generated by GC automatically
Export terrain as a Wavefront object (.obj).
Changing the obj file into a 3ds file using Vue or Cinema 4D
Import of the triangulated mesh (3DS file) into Sketchup.

At present i can't see any way to separate the terrain mesh from the Vector road. It is exported as one triangulated mesh.

Hm. I see. Too bad actually. The other option would be to soften the whole surface, turn on hidden geometry and unsoften the bordering edges of the road manually (Shift+Ctrl+Eraser tool) but certainly that's a whole lot of tedious,manual work although can be done at the weekends while one's wife is knitting beside)

Just dragging this topic up again.

Being unfamilliar with the "follow me & keep" tool, could someone please explain how to use it? I get absolutely nonsense results when I use it.

Hi Macker,

create a line and the end a Profile, in this case a rectangle. Select the lines including the rectangle and choose follow me and keep.

Hi Majid,

for shape bender, you need the road direction line from the first step. This i forget to mention.
Sorry that i answered a little late.
