Pipe Elbow with ferrule

[tkinsley]

I created an elbow that needs a ferrule end,  I made it with a revolve but can not seem to get the revolve to constrain to the angle parameter or to the end of the sweep on the right side.  I made a reference line to host which is flexing correctly.  I even tried making the revolve a nested family but that did not flex correctly either.

I had a quick look at your model.

To properly rotate an object in Revit you would have to fix it to a reference line (not plane).

So a nested family (easiest) is a good way to go. Make sure (what you already did) that the nested family is “work-plane based”  and “always vertical” has been set to off.

In the host arrange for a reference line and make sure it rotates properly.

Insert the nested family and attach it to the workplane and further constrain it to your needs

Have a look at this explanation

It explains in detail how to make objects able to rotate around all three axis.

The reference line with angular dimension in nested family was what I was missing.  All good now.
