"Merging" different wall types.

[Elovia]

Hi Keith,
The connections that you're seeing are caused by how you set up the wall layers, and specifically, which layer you selected to be the Main Layer (see the radio check button left of the layer thicknesses in the wall definition dialog). The software will connect walls together at the main layer. In your example image, it looks like you've defined the thick grey layer as the Main Layer, and all connecting walls connect through the other layers to that one.

In the Wall Specification dialog, on the General Tab, you should see a setting for "Wall Butts Other Walls". This may or may not solve your problem at all locations, but it is worth a try. Otherwise, you may need to rethink on your specific walls and wall types, and try to come up with a definition that better meets your connection requirements (meaning, choosing a more appropriate Main Layer).

Good luck.
