I’ve used ArcMap with a DEM (Digital Elevation Model) to produce contour lines from a region of 10km x 10km approx. I have performed a smooth line to have nice smooth contour lines that I’ve imported into Rhino for further modeling. The model is scaled down in Rhino at 1:25 000 to have a model of less than 18 inches square. The goal is to use this model to make a CNC milled topography.
I used the Patch tool with points extracted from curves to build the surface but I can’t get it to work. I’ve tested many parameters in patch command but I get random results every time.
It looks like the image below. Can someone point me in the right direction to solve this ?
I can upload the file if someone want to look at it.
