Prevent components from passing through other components.
Restriction: Only available for components.
The default behavior of the Move tool allows components to
pass through each other and overlap uninhibited.
Figure 1.
When the collision detection option is activated, an attempt to collide two
components by moving one of them results in the component stopping at or before the
point of collision. If you attempt to drag the component past this position, it
remains in the non-penetrating position and the feature edges of the component that
is blocking the motion are highlighted orange. If you continue to drag the component
all the way through the blocking component, the dragged component will move once
again until it encounters another collision.
