Assembly into a assembly question

[MichelleRaley]

I have an assembly file with 3 assembly files in it. The problem is when I place my .iam flies in there, they become whole parts. Example. I have a assembly of a boat motor. In it I have a drive constraint which turns the propellor 360 / 300 times.

When I placed the motor into the boat assembly. The motor because one part and I couldn't get my drive contraint to work.

Typically we refer to assemblies in assemblies as "sub-assemblies"

And you need to right click on those sub-assemblies and choose "flexible"

Thanks, I've already tried that, though. It had no effect except on my angle con. on the propellor. When I right click it I no longer have the option to use the drive con.

When I remove the flexability and add adaptive instead. I can click click my drive con on my angle con and hit play but I get an error "Cannot solve at (or near) this point. Check drive parameters and adaptivity settings

See attached.

Create a pos rep in the motor subassembly that supresses the angular constraint

In the assembly, make that pos rep active and the sub flexible

Add a constraint between the prop and the boat or the assembly origin, as appropriate

Drive this new constraint

yeah sorry I didn't add that the drive constraint needs to be applied in the upper level assembly and not the subassy.

Tthe subassy still needs to be set as flexible as I first posted.

Thank yawl very much. My propeller is spinning!!!
