Hi there, weird problem. Ive been happily modeling away, draw a rectangle on a box for example then extrude cut that rectangle through the box by selecting the PP tool, selecting the area to extrude then rotating the box to select the face on the other side to create the cut thru the the entire box.
Now all of a sudden, sketchup wont let me do this anymore, it lets me extrude shapes but not cut extrude.
Any ideas on what could be going wrong? Ive read about lines preventing extrusion, or faces not being parallel, it is not either of these causing it. The problem exists when things are components or grouped. Im totally stumped.
