Can't align nested family to reference line

Hi,

 

I'm trying to align a nested family to a reference line in my host family so that it rotates around a certain point.

 

I've created the reference line in my host family, locked the end point to two reference planes and then gave an angular parameter to the angle between the ref. line and the ref. plane.

 

I then inserted the nested family and aligned it to the ref. line. The problem is that when I flex the angle, i get a "Constraints not satisfied" error..

 

What could be wrong?

 

I'm using a generic face based family for both host and nested families...

 

Thanks

You are on the right track. But, it is not necessary to lock the nested family to the reference line in the host. Simply place the nested family using the "workplane" method of placement, instead of "place on face". Since you already put the nested family there, now select it again and find "edit work plane" or "pick new" "workplane", and select the workplane of the reference line. Then with the Move tool you specify the location of the object on its new workplane. It works as if you were just placing an object on a tray. The object doesn't need to be anchored on the tray.

Hello All,

 

This is my first post.  I'm a long time CAD Designer, but fairly new to Revit (6 months).  I'm having the same problem as the original poster.  I originally did the exact same thing he did by aligning the planes in the nest family to an angled reference line in the host family.  I got the exact same results when I modified the angle parameter.

 

After I read Alfred_Medinas reply, I thought his advise would fix it.  It didn't.  Now, when I  modify the angle parameter, the refence line does move.  But, the nested family doesn't move with it at all.  I'm new to the laws of Revit. I really don't see why it would move without some sort of alignment to the angled reference line.  I need help baaaaddd.  My hair is too short to pull out (which is even more frustrating).
