Multi-level assemblies with motion

For what it's worth, I usually plan on putting everything I want to move at once in one assembly. Either that or (to test a few configurations, not motion) moving one subassembly, then saving it, and then going into the main assembly and hitting update

Nice subassembly organization to save time and keep things clean isn't conducive to handling motion the way you do. I used to do it this way, until someone on chief tipped me off to the solution.

-Right click on a subassembly in the feature tree, and go to "component properties".
-Near the bottom right, there is "Solve as". Set this to flexible.

Enjoy cleaning organization and all the movement you want!

I find keeping every movable part movable annoying, so I often set things back to rigid when I'm done analyzing motion.

A bit further off topic, sometimes when a design is closer to done, I'll mate the systems into all their possible positions and have each as a configuration at the top level. So you have a "load", "shoot", etc... configuration that shows all systems in their appropriate location.

Alright, what you need to do is make sure that everything that needs to be constrained is constrained first. Once that is accomplished, you can right click on all of you sub-assemblies and make the option "flexible" checked. Also, if an assembly is grounded, it will not be able to move.

P.S. Inventor is also very finicky, so it might not always work out the way you want it too...
