Move vertices down to surface

pbacot · 13 May 2019, 09:00

I want to move the edge vertices down to the surface below (in z direction). So it would be nice if I can select along an edge and have all the vertices of selected edges move to the nearest face below. Is there a plugin that does this? The two surfaces are in different contexts.

I can do this pretty well one by one manually, but I have a number of them to do. Just wondering.

If I understand correctly. If the bottom surface is flat, the Projection plugin. If not, you can use the Sandbox Drape.

Projection plugin: https://extensions.sketchup.com/en/content/projections-and-guide-tools

mod = Sketchup.active_model

SKETCHUP_CONSOLE.clear
edgs = sel.grep(Sketchup;;Edge)
if edgs[0]
  vers = edgs.map{|e|e.vertices}.flatten.uniq;
  vecs = []; vrts = []; axis = [0,0,-1]
  for v in vers
    p=v.position;
    h=mod.raytest([p,axis]);
    if h
      vrts << v;
      vecs << p.vector_to(h[0])
    end
  end
  ent.transform_by_vectors(vrts,vecs)
else
  puts "select edge(s)"
end
