I just updated to X17, this is the first time I have had to import a 2D dwg file and wanted to trace over the file like in the past selecting intersections or lines. Why does it no longer snap to the imported files? What setting do I need to adjust to be able to select to line objects? Help.

Does anyone know how to create a hole in a concrete wall or concrete floor? I can make a opening in wall with door and remove jamb, caseing, etc. but want to put something in its place. the door opening symbol stops other items in door opening. I can subtract objects with 3D solids but walls and floors another issue. Floor I need to have a hole for sump pump well but again no way to create just a hole in the floor? I tried stairs but once stair deleted hole goes away. Chief 14 Premier. Ken
