I am new to Bobcad. I am trying to figure out how to put counter bores and holes in a solid. I draw the part as a wireframe with the holes in it, and then extrude the surface then try to extrude the holes and counter bores. The holes and counter bores dont show when I render it. Any help would be great. Thanks.

Check to see if you have an extra surface covering your counter bores. You can also Extrude your rectangle with just the bores and do the counter bores later.

Cheers!!!!!
