Hi Guys, I am facing a challenge modelling a terrain. I build existing terrain based of point cloud, but now I have to identify buildable ares. It is easy with the slope analysis, but in some areas I am allowed to modify the terrain to provide more usable area. I can’t come up with any useful idea…

You won’t be able to operate on the mesh vertices only. The chances of a specific vertex having an exact slope angle are vanishingly small, meaning you need to add a tolerance, meaning you’ll get multi-point regions in planarish areas and still gaps in wildly fluctuating areas. If you mesh is stric…

Thank you Laurent! Got it! Sorry about the file. Do you know if the same approach millwork with round-about as well? It looks like making roads based of centre line is a way to go, but can’t find a way to connect different roads, make clean junctions and round-about. I did find a way to make clea…

There is always a solution but here just with mesh. As you imagine there will be some problem at the intersection. So I used Clipper offset of poyline the output curve is used to make a road surface on XY plane, then this surface is meshed and for each point of the mesh I seek on the closest point o…

Cheers! I will try it tonight. I still thinking about another way, where I draw all roads without centre lines, project them and straiten. Will post some experiments tomorrow.

Hi guys, just wanted to show a tool I made for making simple roads on terrains. It is not sophisticated yet, but it works quite reliably. This is made with python and splits the mesh to generate a sharp road edge. [image] [image] [image] Now the roadfill is distance based and the plan is to m…

By the way, this is a script I originally made it for V5 back in 2014 that now runs on V6.

Hi! this is what I did playing around with shortest walk and roads.

Hi Holo, Thanks for sharing. Looks very clean. Can you share the script? I am currently still looking for a way to make roads from road boundary and not from the centreline. It is easer to design road in 2D with correct widths and junctions, but then don’t know how to project them. Cheers,

Hi Holo, I too would like to use your script, it is hard to find a simple way to do this operation short of Civil 3d or In-Roads. Thanks,

Hi Roman and Sullivan, I’ll see if I can spend some time on it during the start of the week, but I need to bugtest a few things first as it uses Rhino’s built in meshsplit for part of the operation. Could you please supply a typical mesh you would use? Together with a road line? Right now it is a …
