@gt22 in 2012 I did that but 2013 I didn't do it anymore and in 2014 I start again "what the is this"
@Lucas yes that's right, but normally it asks you if you want to delete at the same time and then it only deletes in the general constraints, not in the constraint folder of each part that has been subjected to the constraint.
@Pascal is what I do but as I'm lazy I'm looking for something in 1 click ;-)
Otherwise, if you want to start a macro, here are some ideas, but it's not very interesting unless you have several hundred constraints to remove or you have to do it often:
Or a solution to have all the constraints in one window:
Select ALL the parts of the assembly through a window with the mouse, then by holding CTRL right-click on a part, and click "See the constraints" (icon with paper clip and glasses):
The list of all the constraints displays, by holding CTRL to select several of them, it will go faster!
