I made a parametric vise of the Pierson RotoVise using youtube tutorials. Within its own file it works as intended (attached RotoVise_Mixed_Jaws). The image below shows how the stock is within the jaws and the fixed body stays at the origin seen at the right. If I change the stock size via the parameters then only the stock and sliding jaws move.
My problem is when I insert the vise into another design to model the fixture setup for machining; I believe this is the suggested method. Once I insert the vise and break the link so I can change the parameters, then some of the joint relationships are no longer functioning. In the image below I inserted the vise into a design and then moved the fixed body to the origin and created an as-built joint so the origin would be at the right side, like the above image. I then increased the stock size, and that caused the fixed body to move to the right! You can see how the origin is within the vise instead of being fixed at the right side. It appears to be keeping the sliding jaws in place and moving everything else. I attached the "Test vise" part so you can see it in action.
This is my first time doing assemblies in Fusion, so I'm likely missing something, but it doesn't seem right that the as-built rigid joint is being violated when changing the parameters. Why isn't the parametric vise behaving like it does in its own file?
