Push/Pull Tool: Creating voids

Creating voids

Push/pull will implode the shape into the volume and toward the back face of the volume when you use push/pull on a shape that is part of another volume. SketchUp will subtract the shape and create a 3D void if the shape is pushed completely out of the back of the volume as in the following example.


Note: This operation only works when the front and back faces are parallel. Such as when you have two parallel walls in a house and you want to create a void for a door or window.
