You can detect collisions with other components when moving or rotating a component.
The software can detect collisions with the entire assembly or a selected group of components. You can find collisions for either the selected components or for all of the components that move as a result of mates to the selected components.
Physical Dynamics is an option in Collision Detection that allows you to see the
motion of assembly components in a realistic way. With Physical Dynamics enabled,
when you drag a component, the component applies a force to components that it
touches, and moves the components if they are free to move.
To detect collisions as you move or rotate components:
