Void cut causes detail items to disappear in section

[dbroad]

I created a counter family and added some visibility options for some regions drawn in the center l/r plane of the counter from the right/left view direction.  Seemed to work great. I could use basically the same simple geometry for most of the counters. When I cut in section, the detail items articulated the materials of the top and subtop.  Worked great until I realized that any void cutting anywhere through the counter, like adding a sink that has it's own void, caused the detail items to disappear in section. Seems buggy to me. Even if the sinks are deleted, the detail items in section won't reappear.  Here are pictures of the before and after. Any ideas?

Hard to follow. Post the Family.

Confirmed.

If you draw the detail in a shared family and nest it in the casework family then you won't have the same issue.

Thanks.  So,

1. instead of using a detail item family, use a casework family that replicates all the parameters and put all the detail items in each view direction in that family.

2. make it shared so when nested, it will still work when the counter slab is cut.

3. You turned off the slab visibility left and right but that seems not to be necessary.

One more question:  When in Section 1 in the SlabCounter.rfa, I select the filled region and its just that, not the nested slabcounterdet family.  I can't select the detail family itself.  Is the nested detail family placed or just its parts?  I see it show up in the families list.
