Indeed, thank you for the answer. Nevertheless I increased the mesh at maximum and now it s veeeeryyyy close, so yes, I m pleased with the result. For users like me...PLEASE LOOK IN ALL THE PARAMETERS and change the grid to where you consider it is sufficient. Again, thank you for your genius addons, I use them a lot, sketchup would be a pain without them.

Hello Fredo, nice to meet you in the first place I have many addons from you and they are incredible. Regarding toposhaper please help me.. I have a terrain generated starting from an import from dwg. with 3d polylines. The problem is that the curves are not contained in the terrain as if you do it let s say with the native "from contour". In the pictures you can see the curves ( i activated transparency) and then without it you can see that in many areas they are inside the terrain. Can I make a setup in order to have the terrain exactly on the curves? I have tried to divide the curves with Tig's C points at vertex and than to use your trimesh terrain but it s a huge task, i prefere it from curves
