So I’m clearly going about this the wrong way and was hoping for a nudge in the right direction.
I created a shape and then selected pieces of it to put into groups and layers. For example making a shelf. In the pic/link below, you can see that the beveled board simply resulted in a hollow shell. No problem right? Just select the edges and create a surface. Excellent, but the other side has no edges. I assume when I created my initial shape, and grouped and separated everything, that these edges are now part of another group. What’s the most effective way to add these edges back to the existing surfaces, so that I can then create another surface to close up this shape? I’ve tried various snapping options in order to sketch in new lines, but nothing seems to line up properly with the edges of the existing surfaces.
Is there a way to tell a surface that I would like it to have edges?
