Better Simplify Contours in SketchUp with help from Autocad.

[@ludohugo1]

Thank you for the great tutorial May I please ask you : In the first 44 seconds of your video, how you obtained such detailed textures of your topography (is this a picture applied to the surface? or is it really contour painted with your own textures? or is it an other technique?). How did you obtain such a fantastic result? Thanks for your help in sharing this. This look amazing !

When I run the lisp as you did it weirdly moves the contours onto odd elevations. like elev 747' - 2". Am I doing something wrong or is some peculiarity in my drawing?
