After 2 Days of fiddling about … I discovered the 2 second solution …
Select Connection Constraints
Tick Breakable
… THEN RIGHT CLICK the Ticked BREAKABLE
…Copy to Selected
I tried selecting all constraints and ticking the Breakable on the right but they seem to want to be individually ticked to Breakable
shift g and selecting them by Type and press breakable on last selected doesent work
Shift g and selecting by collection and pressing breakable doesent work
?
