Void Family (Hollow Floor Slab)

[Anonymous]

We are trying to create a Hollow Core Slab using a nested void Family. However, the voids do not interact with the floor slab.

Os there a Problem with using a slab or Surface template? We do not have a "void template", if there is such a thing. Or is the Problem somewhere else?

Use a nested face-based void family.

Face-based family cutting the hosting solid, and with Cut with Voids when Loaded enabled.

Thank you, it works. Now we would like to have various different void types (e.g. square, rectangle, circle etc.) which are controlled by a type Option through visibility or some other function / Parameter. Any solution for this Problem?

Make different void families as generic models, nest them into a host family and here create a family type parameter : generic models, place one of nested families to cut a geometry of a host family, 

assign a label to that nested void family, create types in a host family and assign a proper nested family as a value, loaad into a project , changing a type of a family will change shape of cut.

Hi there.

Probably, you haven't told the void to cut the other mass. If you send your file, I can help you.

You could make a mass of floors and void cut them, then turn the floor into the hollowcore family.  Here's a video I made on void cut floors made from massing elements, enjoy!
