Brand new to SketchUp, I’ve just finished a handful of beginner’s tutorials following a provided plan that was just a single room with exterior walls only. Now that I’m onto my own projects, I began by drawing the exterior walls with rectangle tool and deleted the floor. When I try to add interior walls, the geometry is not attached to the floor but to the height of the exterior walls. I realize I can push/pull downward, but if I try to add geometry for say, cabinets…it looks like all new geometry is being drawn on different planes, sometimes attached to floor sometimes weirdly in the Z plane.
Separately, as I’ve built an interior room, I can’t seem to extrude the doorway away like I can with exterior walls.
