Hi All,
Yesterday I was working on a custom sun shade profile. Thinking I was smart & going to save a ton of time, I created loops for all of the continuous elements of the sunshade. When I loaded the profile into my project I received the attached error message. My question is why can I not have multiple closed loops in my mullion profile? I can do it with other family categories. Is this a wishlist item I can vote on?
Thanks,
Jeff S.

The reason is that Revit understands a profile mullion family as something that is the sketch of an extrusion. Therefore, all the same rules for creating a valid sketch for the extrusion tool apply here. If that profile would not work with a solid extrusion, it would not work as a section of a mullion.

Alfredo,
I just tested this, and this profile works just fine as an extrusion or a sweep, just not as a mullion profile. Maybe I'm misunderstanding your post, so please test the attached profile family.
Thanks,
Jeff S.

Yes, but it has multiple closed shapes. That's the additional rule that applies to mullion profiles, which I forgot to include in my previous post. That's what the error message means by "more than one profile loop".

I understand that is a rule for mullion profiles. What I don't understand is, why is it a rule for mullion profiles? Why are mullions so different then any other family, that this has to be a rule for them? I don't see why is should matter how many loops I have in my profile, as long as the profile is a legitimate profile (which it is). It would be very easy to modify the curtain wall mullion type to one with sunshades, without having to do a bunch of additional work on the model, if this worked.

I don't know. Revit understands the profile as a single closed shape to be extruded. I suggest to create the sunshade as a separate model family.
