Rotating a nested family with Parameter

[cslatteryAXGRE]

I have a nozzle family I made for a tank. I brought it into my tank family, I want to be able to rotate this nozzle after the tank family is in my model. I placed a reference line, I aligned the nozzle family to the reference line and locked it, I added another reference line perpendicular to the first reference line, constrained them at 90 degrees, aligned and locked the nozzle family to that reference plane, added an angle parameter between the first reference line and the default reference lines, when I go to rotate this with the parameter, a Constraints Are Not Satisfied message pops up, and the reference line rotates but the nozzle with either rotate with it but stay horizontal or will flip around 180 degrees. I know this has been talked about before but it is just not working. This seems like it should be simple but it is not. Does anyone have any ideas?

Host, not align, the nest family on one of the reference line's plane (TAB to pick).

Am I using a Reference Plane for a Reference Line. This image I put in both. Each highlighted and I placed them on the lines, but I don't think this is right.

Does it have to be a faced based family?

[ToanDN]

- The nested family can be face based or work plane based.

- Must use Reference line, not Reference plane, to drive the rotation.

I had it work plane base, it did not work, but the face based did work.

[ToanDN]

A work plane based family definitely works.  The mechanism to pick the host maybe slightly different between the two.  Regardless, if you already have had a face based to work as intended then so be it.

Hello,

Always Vertical is checked in the nested family?
