Best practices for closed door/open door configurations?
(OP)
I do a lot of work with aluminum cabinets, and our customers require views with doors open and closed. Our doors typically have a door stop that slides and changes angles as the door opens and closes.
I have tried using flexible assemblies, but they often give me problems. Angle mates either flip alignment randomly or don't go to the side I want them to go to. Perpendicular and parallel mates give me similar problems.
Are there any "best practices" guides for flexible assemblies?

RE: Best practices for closed door/open door configurations?
I have been fighting the "flipping mates" problem more frequently with each new release. It is especially a problem with distance and angle mates. I use more assembly-level sketches and datums for mate references, now. This has helped considerably.

RE: Best practices for closed door/open door configurations?
Right Now if you make a config and put a mate on one part its fine. If you change configs, suppress that mate and make a new mate 180 degrees from where the other part was located at. It will maintain that location even when you switch configs.
I don't know if either of you have seen this, but I thought you should know about it, because with Flexible assembly and stuff like that COnfigs are used often and some mates are suppressed so a part can be moved to a new location.

RE: Best practices for closed door/open door configurations?
Ken, I have tried the limit mate without much luck. If my door opens past perpendicular in my "open" config, the slide tries to go to the outside of the door in the "closed" config, rather than stay within the slide and remain on the inside of the door. It tries to take the shortest path to the closed position and creates mate conflicts between my mate that constrains the slide in it's slot and the limit mate. I'll try to post screenshots when I get some free time to make it more clear. I suppose I could constrain the slot so the door doesn't go past 90 degrees, but I would prefer not to do that.
Thanks to all for the info.

RE: Best practices for closed door/open door configurations?
These are very large assemblies, and I would prefer not to have two sets of doors due to the amount of time required to completely constrain each individual door. Considering the trouble I've had with adjusting a single door, it's one of those things that probably would have been quicker to do at first, but I feel like I've come to far to completely change everything. I'm sure we've all been there. :)

I had problems like everyone else with mates flipping when I switched between configurations. I noticed two different problems with what I was doing wrong, one I wasn't mating planes to planes which have additional mate options like flip mate and when that failed I figured that the planes I was using didn't necessarily intersect at my hinge point. Now I don't have any problems.
Step 1. What I do is create two planes in my assembly through my hinge axis one which represents my closed position and another plane which represents my open position. I also would create a plane in the part which is rotating (your door) through the hinge axis if one does not already exist.
Step 2. I create three configurations as follows:
#1 Closed config - mate the assembly closed plane with the plane in the part.
#2 Open config - mate the assembly open plane with the plane in the part.
#3 Free Rotating Config - create a limitangle mate between the assembly closed plane and the plane in the part.
I hope this is helpful.

He's not battling flipping mates, but you just have to be sure that you make another assembly with things mated into place solidly for assembly drawings.
