    Unhappy [Help] AEC Walls disappear in 2d, Appear in 3d. Sometimes.

    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?

    Follow link for visualization of my issue.

    6" As mentioned in your post in the Autodesk Discussion Groups, if you are using Project Navigator, the expectation for a single-level Construct is that its floor level will be at Z = 0 in the Construct file, and Project Navigator will manage the Z-values when assembling multi-level Views. If the (2D?) line drawing was inserted with the Z-value at 9'-0" and you are snapping to that linework without locking Z-coordinates to 0, then you are drawing those Walls with a baseline at Z = 9'-0". If your cut plane is at a typical value (somewhere around 3'-6" above the floor level), then those Wall will be above the cut plane and will not display.
