I have a detail component nested into a mullion profile. There are some reference planes in the detail component and the mullion profile to help place other relevant detail components in the project. Revit cannot seem to find these reference planes. This only happens in mullion profiles. Why can't it do this?

Not sure that I ever had your need but do you understand "Is Reference" described here in your help.

Though I typically don't nest detail components into mullion profiles, what I'm finding is that the reference planes placed in the detail component family cannot be read across the profile family and into the project - weak or strong (which I fully understand). So that's the thing: Why won't Revit allow for these reference planes to be read once in the project? If the detail component was loaded outside of the profile family there would be no issue. This limitation seems to negate the versatility of including a detail component in the mullion since it really only acts as a graphic and doesn't seem to be much of an asset to the drawing. Unless there is another setting that I’m not familiar with in the profile family?

You have to add a strong reference in the host family and lock it to the nested.  I don't know if you can do that for mullions.

I personally don't like nested mullion details.  You can't control them at all.  I like to control the break location for mullion details so I can adjust that as needed in the detail or section.  AND  Sometimes the CW is not quite in the right place in the model but I never dimension it there anyways.   I always dimension where the CW is ...in the details.  So I don't want the model location controlling my detail.  ONE OF THE FEW areas where my model is not quite correct.

Yeah I tried exactly that and the only references snap-able are the center axes in the profile family. I can see why you stick to that method. I was hoping to save some time by including them and populating the details that I'm already working with, which does work well. Just not the finer points of dimensions. Thanks for the insight one this 'Hub.
