Variants describe selectable combinations of one assembly. This is achieved through the change of visualization and effect of single components. Thus, assemblies can be created of which different variations can be used through the selection of self-defined parameters. Example: Plug plate with alternatively two or four drilled holes which can also be arranged differently.

The variation with assemblies is achieved through the display and suppression of components. This also affects existing operations such as Unify, Difference and Intersection.
