Confusion about mates, groups and assemblies

Member Posts: 90 ✭✭
I have an assembly, call it ASSEMBLY1. I want to it attach to a revolute mate in another assembly, Call it ASSEMBLY_MAIN. I group the parts together in ASSEMBLY1 and create a mate at the pivot point. I insert ASSEMBLY1 into ASSEMBLY_MAIN and create a revolute mate with pivots. When I run the animation, ASSEMBLY1's group doesn't rotate, only the element the owns the pivot rotates. It seems that the solver doesn't respect groups. Is this correct? do I need to use fasten mates for each part in ASSEMBLY1, or import it as a rigid body?

But also I believe your issue is which animation button you are pressing. If you go inside a mate (as if to edit it) and press the play button there, it is only solving that individual mate, and only one component will rotate.
If you want to solve everything, you need to use the animate in this screenshot, that shows up when you right click on a mate.

Or mate one of Assembly1's parts directly in the upper level
Do you mean I need another mate on Part10,11,or 12?
You can either mate one of them to "Mate connector 1" here, or you can mate it in the higher level (if it makes sense)...
You can "fix" one of them however the fix is "local" (i.e. not propagated to higher levels).

I have a simple arm. If you open the revolute mate and push play, only the base element rotates. If you enter values into min and max, the whole group responds.
By the way, thanks for responding .
