Tip – Creating Hollow Forms in SketchUp

The technique I am about to explain in SketchUp is identical to the “subtract” function in Unreal Editor. It can be utilised in removing ‘solids from solids’ and creating hollowed out objects e.g the passenger compartment in an elevator. Method:

  1. Create the two solids – one which you will subtract FROM and one which will be the SUBTRACTER. (Could use more than two solids.)
  2. Place one on top (inside/through…) the other.

  3. Select all solids > right-click > intersect > intersect selected. Note: no need to make group/component.
  4. Delete all redundant entities to reveal the subtraction.
  5. All faces that were previously “inside” need to be turned “outside”. To do this select the face > right-click > reverse faces.
  6. Voila!

    Play around and make some funky shapes!

    Holla back if you encounter any problems.

Thanks! I've been looking for a clear answer on this seemingly simple command for a few week. Mystery solved.
