Yes. Make sure they connect....slightly overlap. Select and right click, then choose 'cleanups', "apply intelligent cleanup". It worked for me. might also try the 'add merge wall condition'.
Thanks. I was wondering what good reason there might be to upgrade from AutoCAD Architecture 2008. I like the name of the command- "Apply Intelligent Cleanup"- presumably a big improvement over the old "Apply Idiotic Cleanup" command.
If I could open your drawing without the walls becoming proxy objects, I'd pop your walls into my drawing and be done. Wall Merge Condition doesn't work. I guess I'll end up drawing this area with Plines attached to walls without endcaps.
Something like this?
