Hi Ruben,
We are not supporting that Setup Groups worksheet anymore since the V7 changes to the groups and Dimensions tab have taken away a lot the complexity that had to do with setting up groups. Components are automatically assigned to their own group in V7 so a lot of the explicit group setup goes away.
Is the main emphasis simply assigning components to assemblies/groups or is the issue applying the assembly/group settings - concepts, variables, materials? Is it a single variable/material assignment or ranges of variables and materials?
Analysis dimensions and dimension ranges for sizing can still be set using the Set Variables worksheet. Single material assignments can be done like this as well.
