I am currently trying to get a face based family which is hosted to a reference plane to array. All things are good until I apply the array, then I get an error message (see attached image). When I host the family to a sweep it works just fine, until I change the height of the sweep/plane. Then the face based families are no longer face based. I think I'm going to try nesting the problem family into a generic face based family and setup the array there. Then nest that into my main family and link parameters as required.
Any thoughts you could give would be helpful.
Thank you in advance,
