How do I turn a bunch of lines in a plane to a solid? There are so many entity names (region, surface, group, hatch. etc.) that I have major trouble just getting from lines to a 2D surface. Once I get there, I need to extrude this somehow into my 3D solid. Until I do this point, AutoCAD won't let me miter the corners by subtracting 3Dprisms. How do I get to this point?

Thanks,
Bob

I clicked on some of your geometry only to find it is a 3D face.  What is the reasoning behind that?

AutoCAD 2000?  Argh.

Well if you had something a bit more recent you could use the PressPull command to create a 3D solid model from your profile but you don't.  That means you would normally use the Extrude command but because you used 3D faces all you'll get is a surface.

Recreate the profile using lines or polylines and arcs.  Use the Pedit command to join everything into a single, continuous entity then use the Extrude command to give it some height.  The result will be a 3D solid.

I'd only use surfaces if I were doing something like a sheetmetal product.  Looks like you are attempting to create a wood casing which, if memory serves me correctly, can be cut with a saw meaning the casing would be solid wood through and through.  Solid wood = 3D solid in my mind.  Your's too?

Here you go.  Your casing profile as a region.  Use the Extrude command to give it height.  You might want to change to a southeast isometric view to see it better.

Thanks. It worked fine. Can you tell me what you did?

I made your profile a region.
