Mark As Excluded

Parts which do not take part in the motion simulation (usually auxiliary components such as layout, cooling or runner parts) are marked as 'excluded components'. These components are displayed with a red X in their icons. In addition, a check mark is displayed adjacent to the Mark as Excluded option in the popup menu, as shown below.

To configure a component as excluded, right-click it and select the Mark as Excluded option-de-select the option to include the component.
