Allow different weldment states to be viewed in assemblies containing weldment assemblies. i.e. have a weldment assembly only show it's preparation state within an upper-level assembly and not show the final machined state.
My current work around is to suppress the machined features and then derive that assembly into a part. I then suppress the derived link which allows me to go back into the assembly and unsuppress all of the machined features.
