We would like to create openings in beams in the same location down the entire length of the structure (+- 20 beams).  We thought about creating a void in each beam family, but there are many different size beams, and this would be a lot of work,  especially if the opening locations want to move.  (which they will...) 

 Then we tried the "opening by face" function in Revit and it works great, but unfortunately we can't extrude the profile through multiple beams.  (similar to how a shaft opening works with cutting floors)

 I thought about using the opening by face and copying the sketch through the 20 different beams, but again, this would be a lot of work to manage if the location changes.

 We are working on a 19 story building and want a solution that is easy to manage and doesn't bog down the model.  Any ideas?

 

Thanks!

I don't know if this works because I'm not on structures.  Did you try an in-place family - void and before closing the family, piuck all the beams it should cut?

If WWHub's suggestion doesn't work, some reference planes should help you at least keep your openings the same size.

Voids can only cut solids that are in the same family, true for both in place families or external families... 

Since we have many different beams of different sizes we don't want to make a void inside each of those families.  We'd like a "cutting object" that we can create profile(s) in and by moving it, you're effectively changing the penetrations along a whole row of various beam families.  Like a shaft opening cuts floors vertically, we'd like a beam opening object to cut horizontally. 

 Reference planes are a good quality control measure, but they don't solve the modeling/management issue.

 Thanks!

Not quit correct.  You can create in-place family voids to cut families of the same category but this may only work with system families like walls and floors.  You can also create face based families with voids that will cut their host.  I know this works again on system families but may not work on other families.
