New to Rhino. Want to make Topographic/Contour model

Hello - here’s what I get:

again:

  1. SelPlanarSrf
  2. NonManifoldMerge all the planes at once
  3. Select the merged object. This should be all the planes in one object.
  4. UnrollSrf, Explode=Yes.

I always use the plugin SectionTools. Would that work for you too?

Since you’re just starting I want to add: It’s very efficient but not necessary to unrollSrf. If it’s not working for you, you can do it “manually”. Simply work between the front and the top view and move the pieces around until you get them where you like them. Do this with the on-screen “gumball” and the move command.
