I have submitted this to support, but thought I'd get your opinions.
Here is the situation:
HD PRO 2014
House design in progress with the following:
Full walkout basement using ICFs for all exterior walls.
All exterior walls on first floor use SIPs.
I need to align the exterior surfaces of the insulation on the ICFs with the exterior OSB on the SIPs for siding to go on ICFs and SIPs.
It seems the program uses the main layer of walls to align first floor and basement walls. If I set the main layers to match the surfaces above, the program also uses these surfaces to define interaction of interior walls with exterior walls, so all interior walls intersect into the exterior walls to the surfaces above.
I had set the main layer to deal with the interior/exterior wall interaction, but now I can't get the first floor and basement walls to align.
I must be missing something.
