    Help with Pipe Elbow Annotation

    I created three custom pipe elbows, but one of them does not display correctly in medium detail. I can't seem to track what I missed. The fitting works correctly and all 3D element display fine, but just the annotation when the pipe is dropping or going up shows offset.


    If anybody can give me an idea of what setting I might have missed I would greatly appreciate it. I have chacked that all my annotations are locked to the correct reference planes within the family.

    Could you post the family?

        Sorry I took so long to reply. Went back to school and then work got busy...

        So, the issue with your family is that the arc/ radius is not constrained in relation to the origin of the family; this let's it float around whenever you place it.



        If you look at the attached image, the family on the right is an OOTB version and the one on the left is your family. You can see that the location of the centre of the arc is controlled by two parameters. in the OOTB family the centre radius and the centre-to-end parameters control where the centrepoint of the arc is located in relation to the origin of the family. The centre radius is also applied to define the radius of the arc. Your family makes use of the centre-to-end parameter, but the centre radius is never defined/ controlled, and I'm pretty sure that is why your lines are all wonky.

        I would recommend learning/knowing how to build a fitting from scratch. To that end, the excellent pdf guide attached below offers a pretty easy entry into the world of pipe elbow building. As a side note, I always find that it is easier to just (re)create the fitting from scratch than trying to figure out what is wrong with it, but maybe that's just me...

          Thank you! That really points out the issue. I agree that it is usually better to start from scratch for pipe fittings and that guide is a lot better than the one I had been building off of.
