Unexpected phasing behavior when mixing Void Extrusions and Opening Cuts

[joshua.natzke]

I've created a series of modular door & window families that rely on nested trim and panel families. However, when phasing/demoing these families, I get weird artifacts.

The trim family is a Generic, face-based family with a void extrusion to cut out the brick around the brickmould. When the door also has a void extrusion, it behaves as expected but doesn't cut walls that get joined to the host (like furring added later). I've been getting around this by using Wall Openings manually sized to the doors or windows.

The odd behavior is when I start mixing the nested trim family with a Door family that has an Opening Cut. This correctly cuts through any joined walls, but for some reason the void extrusion from the nested trim is not phasing correctly.

Any thoughts? I've tried checking and unchecking "Cut with Voids when Loaded" in both the door and trim families, but to no avail. We can continue using manual wall openings, but that requires more coordination. See images below, and attached project.  Thanks for any help.

Make the nested family Not Shared.

Interesting.  We use the nested trim families on a number of door & window styles, so I'm not sure how workable that solution is at scale.  But it's good to know there is a way to fix it.

I wrote this blog post regarding the use of voids vs openings after participating in another thread here. It boils down to "don't use voids, use openings...if you want phasing to work". In this case they wanted to replace existing with the same size windows. If the windows (or doors) are different sizes then it is less unreliable.

I was afraid it would be something like that, given that I've experienced the same error described in your blog post.  Looks like it might be worth rethinking how my families are set up.
