I am trying to get two hinges to move together, but for my years with SW, I haven't done much with flexible mates. I dumbed my problem down to the simplest parts and assemblies that I could, and I still can't get it to work out.

• When there is no limit on the rotation, it works fine.
• If I use a 0-30° Hinge mate in the sub assembly, I get a tree full of errors.
• If I use a 0-30° AngleLimit mate in the sub assembly, I get a tree full of errors. And not just on the top level, but on the base level as well.

All of these seem like they should work. What gives? Either advanced mates and flex ass'ys don't work well through different levels, or I'm just flat out missing a piece of the puzzle.

Hopefully my attached files come through okay.

Both the sub assembly and upper assembly have configurations to toggle through these scenarios.

Thanks,

Pete
