Wall heights?

[function9]

I have some external masonry walls that don't seem to be created at the same level as other walls adjacent to them. I'm not sure what I'm doing wrong? I'm assuming they need a floor to 'connect to'. In Revit I can select a wal or multiple walls (if similar construction) and in the dialog enter the overall height of the wall. I can't seem to find anything like that in CA?
Also, in the corners of some walls at high level there appears to be something strange happening. I'm guessing this has to do with wall intersection start & finish thru-framing?
