This should be pretty basic because according to the help file it is possible to:

"You can control the following parameters in an assembly design table:......mates – dimensions of distance and angle mates, suppression state ..."

I haven't had a use for it until now and the help file is as per usual only good for stating the obvious and hinting at anything else.

Can someone please inform me how I can define the Angle2 mate (see screenshot) in a designtable?
