If you work with 3D printing, CNC machining, or complex architectural modeling in SketchUp, you have likely run into the dreaded "not a solid" error. SketchUp requires a group or component to be a completely sealed, watertight volume to recognize it as a solid entity. Finding the tiny gaps, stray lines, or internal faces causing this issue manually can take hours.
