I'm working on a multi-level residential building in AutoCAD Architecture 2012. The construct I have open is set to be around 9' above grade.
I'm having some trouble with my custom walls (as well as the pre-defined walls). I have line drawings from a client of the exterior walls. I'm adding interiors using AEC walls. Unfortunately, they oftentimes disappear if I draw them starting at one of the exterior (line) walls. Sometimes it doesn't even matter. Strangly, I can't see them from a 2D view, but a 3D view causes them to show up. I suspect there are certain "zones" that cause this disappearance.
I clearly have a lot to learn. Can anyone help me out with this? And point me in the right direction for further learning?
