Chase wall for plumbing

[Elovia]

As you can see in the attached sketches, the interior perpendicular walls of the Elec and HVAC closets don't stop at the chase wall, but continue all the way through and if you notice the screen shot of the camera view now CMU is showing penetrating the drywall finish.

Note that when you created your custom wall type, one of the layers is designated as the "main layer". Also note that the layers are displayed with respect to the exterior surface (i.e., the exterior surface is at the top of the stack of layers displayed).

So ... what I'm about to say may be confusing but I'll give it a try anyway. All walls have an interior and exterior surface depending on how they're drawn. This is true even for interior walls that we generally understand to have an interior surface on each side. In the Preferences dialog, under Edit and in the Selection area, there should be a check box for "(S)tart and (E)nd Indicators". If you check that option, accept the change, and then select a wall in plan view, the selected wall will show the starting and ending points of that wall, thus indicating the point from which and the direction that the wall was drawn. In general, going from Start to End, the software's recognized interior surface will be on the right-hand side. This image should help visualize the parameters I described:



OK ... that said, it is possible that your main layer is on the opposite side of the custom double wall type that you created because of the direction that you drew it. Other walls connecting into your custom wall type will try to connect to the main layer, so that behavior is expected. In your custom wall type, it appears you've set the main layer as the inner of the two "walls". Check to make sure the main layer is actually where you want it to be based on the (S)tart and (E)nd points of the wall you drew.

Hope this helps.
