First off, I'm trying to add an arc wall to an already existing wall. It adds but only aligns with the outer edge of the wall. When I try to meet lines I get an error "lines belong to different work planes" how do I fix this. I want the section of the wall inside the arc diameter to go away and my current wall to connect to the arc wall to make one solid wall.
Second. I cannot seem to figure out how to stack my house. I have had to draw all 3 floor plans as separate drawing, basement, first and second, and can't seem to get the roof tool to align on top of my walls either. When I tried creating a new layer "first floor. It just created everything right in top of the basement workplane.. Any help would be much appreciated. I've only been using TC for a couple days so bare with me. I get the hang of stuff fast but am brand new to CAD.
