Revit 2021.1.3 - Having problem in joining two structural beams, one pre-cast concrete and other concrete.

I am having issues about joining two structural families that i have created. Should I be careful with something when I create the family so join can work?

Hi @loprast711 

A concrete beam will not join with a precast beam, what you should do is disable the option to disallow joining and then cut geometry.

but I can't join or cut geometries.... and if I use COPE, converting the concrete for pre-cast concrete beam it also cuts wrong. Its cut's instead being the intersection in the support, it uses the geometry from the middle of the beam.

Already tried converting the pre-cast beam to concrete beam, it won't work either.

when joining objects they should be in the same materials? thanks

[loprast711]

Not necessary, it just has to have the same category in material but not necessary the same name. Already done similar things in other projects with other families but this one is not working.

post here part of it so we can check? thanks

The section is composed by 3 extrusions and 2 blends.

I tried also to use the "cut with voids when loaded" so when I have a beam connecting to this element, it should cut automatically, but it didn't work as well. I add a paint in my structure so I can calculate forms automatically, it shoudn't change the result either because when I remove it, it doesn't change a thing.
