Hello

I shall begin with the issue of "Families". Specifically "Generic model" and "Generic model void".

Below you may find some screenshots.

what exactly happened.

I need create "family" with this 2 objects. After then i need to move it near to other object.But i get some warning.
I need keep this small distance between them. I do not mind about "UNjoin" its.
But Revit want to delete "family" any way.

it's hard to explain. PLS check the screenshots. By parameters my Void moving to that dote

and than i get warning

here i added to parameters +0.1mm but still warning

another sample of this type of problemm

Revit has limitation about their geometry if you want to tried this i recomend use at least 0.5 mm o 1 mm distance to the element that you want.
