Proposal to make IfcRelVoidsElement a one to many relationship --> IfcRelVoidElement

Open TZwielehner opened this issue 3 years ago • 2 comments

In some of our models we have quite a lot of openings, especially for slabs. It would be much easier (and leaner) to have one relationship manage multiple openings at once. I don't think it is necessary to have each IfcRelVoidsElement as a rooted element; maybe a set/list would be more efficient?

My request is the other way around. Atm I need a rel voids for each opening in every element e.g. slab. I would like to combine those into one rel void with on relating element and many relating openings.
