Noob here. I’ve been trying to create a keyhole but am not sure how to create the channel wall. I create the circle, the rectangle, the outer rectangle, extrude the inner part and then I get stuck on what to do next. Been searching the googles but not finding anything for shapr3d. Any help is greatly appreciated!

And this is just to whet your appetite — to give you an understanding of what parametrization is and why it’s needed.

And this one to clarify that almost anything can be done in a lot of different ways.
