Modifications cannot be made within a generative design study, they must be made in the Design workspace prior to study setup.

Modifications from the generative model are only carried to the original assembly if a Connector Obstacle was created.

Modifications from the generative model are carried to the original assembly in the Design Workspace.

Modifications are only local to the generative model in which they are made and are not seen in the original assembly.
