Yes but his question is still valid. I want the quick rotate button to work like it does with MEP fabrication parts. 45 degree increments that way I can make small changes with revit families in 3D if I want. I have checked mechanical settings and don't see this option, it must be somewhere. Thanks.
Hey Andrew, I agree, it's still valid...I just revisited this issue with V2020 because of your post, and the fittings still have only the 90 deg increment options. It appears that this rotational setting is a set parameter and with some quick attempt at editing the settings, I was NOT able to change the 90 deg rotation to include 45 deg. Even if I could, I am not sure I want to make these edits myself and would expect them to be available OOTB. I have always used the cross section method since my original post. Looks like that is our only option. This should be added to the wish list.
Had the same issue-
As I was thinking - this is bass-akwards from what you would think- once I set it to 'ALWAYS VERTICAL" I was able to free rotate on the x axis relative to the family (X= pipe axis). Also noticed mirroring pipes and fittings really screws up flanges and connections and changing pipe types.
(Mark as solution if this fixes your issue please!)
I've found useful to create slopes representing different angles 10 15 30 45 etc and just draw the pipe using the slope that matches my need. The program rotates the plumbing fixture accordingly.
Hope this works.
