Add Dimensions to the Design-Set

What are Element-Rows?

Each Element-Row in the Design-Set can be linked to a dimension or parameter - which you can then edit with the Design-Set dialog.

Important:

After you add a dimension or a parameter to a Design-Set, you can only edit it with the Design-Set dialog.

To edit a dimension or a parameter in the normal way again, you must delete it from the Design-Set dialog.
