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 how to get this work.
- I need a way to modify existing terrain by making some ares flat and be able to calculate cut and fill volume.(attached image, I would like to make red areas flat)
- I also need a way to draw a road in 2d (easy) project road curves onto new mesh and blend the road with the mesh (see attached image)
I tried 3ds Max sculpting and then exporting points back to Rhino, but it is not a very precise way. And if I would have to change something I would have to go back to 3Ds Max.
Maybe there is a way to draw custom (control ) contours and then blend them with existing mesh? This way I will be able to adjust counters shape to fit the design idea ?
