Using rectangle to split face

can one use the rectangle too; tool in place of the polyline to punch a hole through a solid
ie i want to create a rectangular shaped hole thro’ an existing box ala push and pull in sketchup
using the split face command i’m able to push and pull selected subsurface , so could i draw a rectangle on the surface of the polysuface object so i can create a through hole in the box.
thx

Try using the MakeHole command with your rectangle on your polysurface instead.

thanks, one other thing when i use the moveface command it doesn’t pull the surface selected “clean” as in a rectangular box cantilever instead the lower vertical lines of the non-selected subsurface stick to the selected subsurface , so instead of clean boxy cantilever i end up with kind of rhomboid.
is there a way around this
