Searched through the forums here and have not seen or understood if this is possible: I have a generic model nested into a lighting family. I want this nested model to be a polar array where I have parameters that control radius, number of items in array, and equal spacing. So far all that I'm allowed to control is number in the array. Revit will not allow the angles to be controlled in the array. I tried creating a angle dimension snapping to the centerline of the nested model to the next item in the arry (which works in a linear array) to attempt to control the spacing. However, as soon as this is parameterized, it breaks. I've tried this with lines, and other basic geometry and this does not seem to be possible. Does anyone have a procedure that has worked for a similar case?

Thanks.

You might try adding a reference line at your angle, control that and assign the polar array angle then to that line.  Similar to how you control a door swing.

I tried that as well: "Constraints Not Satisfied"

It is possible, with nested families. There are 3 properties to control. At some level of nesting you control some properties, and at the next level other properties. Sorry I don't have the details of this available now. I had it in my blog but is is not available at the moment.
