You can use the suppressed state to remove a component temporarily from the assembly, without deleting it. It is not loaded in memory, and it is no longer a functional member of the assembly. You cannot see a suppressed component, or select any of its entities.
A suppressed component is removed from memory, so loading speed, rebuild speed, and display performance are improved. Because of the reduced complexity, evaluation of remaining components occurs faster.
However, mates that involve the suppressed components are suppressed also. As a result, the positions of components in the assembly can become under defined. In-context features that reference suppressed components may also be affected. When you restore a suppressed component to the fully resolved state, conflicts can occur. Therefore, use the suppressed state carefully when modeling.
