Driven dimension not automatically updating

I have a driven dimension in the attached part. If I change something in the part that affects the dimension it won't update unless I double click it to get the edit dimension dialog and then confirm it.


Changing the contour flange's length will affect the driven dimension which can be found in sketch5 under cut1.


Is this a bug or am I missing something?

Hi! The behavior seems to be related to Unfold feature. There seems to be lacking an update on driven dimension value. Rebuild All seems to fix it.

Another way to avoid this issue is to create the driven dimension on a sketch prior to Unfold feature. Regardless, the current behavior does not look right. I will forward it to development for further review.
