Sorry, but the family is part of a video tutorial that I have made recently on nested families, but I have some restrictions about posting that content, due to my contract with the company that commissions the videos. Are you by any chance attending Autodesk University? These videos will be on demostration at the booth of Axiom International, and I will be there, too.
I won't be attending AU, I may watch some of the presentations online. It's too bad about the family, let me know if you have additional material, forum posts or websites relating to this topic (rotating light fixtures with light source).
Do you know if it's possible to achieve the same results without hosting the family?
As mentionned before, hosting the familiy is not ideal since the hosted family gets tagged as "?" on the drawings and I have to remove each one manually.
I see one parameter of rotation. Where is the other one? I thought you wanted to have rotation in two different planes.
Your comment above about why not to nest the family, is not necessarily true. The issue with the "?" tag happens only if the nested family is shared.
I can rotate the family in plan no problem, the main issue with lighting fixture is achieving the vertical rotation (what I've done in this family). Furthermore, the light fixture I based this family on only has one point of rotation. http://www.junolightinggroup.com/literature/LIT-JU
You are correct about the embedded family, you simply have to not share it in order for it not to show up in the schedule or be tagged automatically (or at all). I had to refresh my memory on what sharing embedded components meant since I thought it would somehow disable the light source. It never hurts to go digging in the Revit Family Guide.
Then, according to your last post, and the .pdf file that you posted, you needed one rotation, only. So, why did you start the thread with this sentence: "I am trying to create a light fixture with a head that can rotate in two axes so that the light can aim up or down and left or right." ? That is something different.
You're right, I made a mistake. It should've said "I am trying to create a light fixture with a head that can aim up or down and left or right." since it is really easy to aim a light fixture left or right.
Using this technique, I will be able to model track lights that can rotate on any axis in the future.
