Draw Overlapping Faces in SketchUp



Hello guys,

I am trying to draw 2 overlapping faces in SketchUp. The problem is that, when the faces are overlapping, SketchUp (automatically) identifies 3 faces, instead of 2 (see Figure below).

My main purpose is to draw 2 overlapping polygons (with their corresponding points/coordinates), in order to “grab” them utilizing a Ruby script.

Thank you very much for your time,


Raw geometry in SU sticks together, to isolate it you make it a group or component.


If you want to avoid them intersecting, you would have to group them before they overlap. The intersecting area becomes its own face, which is expected and normal behavior.


Thank you very very much, problem solved!
