  1. This is arguably a bug. It seems what the push/pull tool is doing is creating a solid addition out of the original extrude and some additional geometry. If I ungroup the solid addition, the original extrude remains marked as "Ignore Closure".
  2. It's used internally to implement things like Sills that "punch through" wrapped finish components.
  3. Objects in the 3D Wall Hole Group of a Symbol gain an "Ignore Wall Closure" checkbox in their OIP. You can see when it is un-checked for this object the faces of the hole are offset from its surface by the relevant closure offset, and the finish component wraps around those faces of the hole. When this option is checked, the object is subtracted from the wall geometry after all of the closure geometry computations are complete (so it will cut through the already-constructed wrapped finish component as seen below).
  4. That is a good point. The honest answer is, given the complexity of the feature, the exact behaviors evolved a lot in the development process, and now I'm not sure. In the initial design of the task we thought of the closure object as the "jamb" object, and this may be a legacy of that mental model (wall should never coincide with jamb). This is true for the objects for which "Ignore Closure" is checked, the others are actually doing double-duty: they define the surfaces that participate in component wrapping (so finish components can wrap into complex hole geometries). For example: from this hole geometry
  5. Getting this 2-D result is actually achievable! Arguably via black magic, but still... Extrudes are valid objects for the Wall Closure Object, and you can create a zero-thickness one by extruding a line, OR, you can stick zero-thickness bits off of it by extruding a collection of rectangles and lines. Any parts of the "wall blob" exterior to the exterior-most face of the wall closure object get offset by the exterior profile offset, and any parts of the "wall blob" interior to the interior-most face of the wall closure object get offset by the interior profile offset. Finally, the closure object is subtracted from the "wall blob". To manipulate VW into doing what you want, you need to a zero-thickness face extending far enough to "stop" that component from wrapping, but there can't be any solid behind it (because you don't want it subtracted from that inner component. It's probably easier to look at the later picture to see what I mean. View of the closure object: This strategy won't work to get all four edges wrapping (because VW won't make an extrude if the rectangle and line don't share a plane, and solid additions aren't allowed as closure objects). However, if the rectangle isn't necessary, you could get this on top/bottom/left/right with a properly-extruded line.
