Using preform 1.6 on a Mac…
I’ve found that the rotational UI values that are shown when I select a part in the view are not always updated.
I am not sure how/why, but sometimes these values go to zero (all of them) and sometimes they show the proper values.
Here are two pictures of the exact same file with the part selected:
zero values in the rotation boxes
proper values in the rotation boxes
My work-around was to close Preform and reopen the file. This does not always occur, but when it does, things get “stuck” and I need to restart.
PS I realize these two pics are taking from a different view point, but the part rotation is the same in both (and the STL comes in in a completely different orientation for its ‘native’ orientation.
