Constrain two parts to same rotation angle (by Henré Botha)
I'm trying to assemble two very similar parts. I want to constrain them in all DOF except that they must each be able to rotate around one of their edges, and the rotation angle must be identical. No matter what I try, I can't get this to work. I always end up with redundant constraints.
In the file assembly.slvs (see attached archive), I have managed to constrain the first part (plate-left) so that it can only rotate about one of its edges. This is done with the help of a construction sketch. The second part (plate-right) is similarly constrained, but as things stand, the two parts are able to rotate to different angles. I want the angles to stay the same. You can see there is a construction line (r00b) in g003 that terminates near plate-right. I want that line segment to be constrained to terminate on the nearest edge of plate-right, which would result in plate-right being fully constrained, and its rotation angle being locked to that of plate-left. But any constraint I apply to r00b and the edge of plate-right results in overconstraint.
How do I make these two parts rotate in lockstep?

Of course, 7 minutes after I post this, I arrive at the solution.

FYI the next version of solvespace (3.2) will have parallel and perpendicular faces constraints. These both exist in the development branch. It's the same menu/key but can be applied to two faces.
