Collision is the tool that determines whether or not items will overlap in the IS7 design environment, that is, define whether an object can pass through the other or not.
To enable and disable the collision of an item, select the desired object and click on the indicated icon:
Active Collision: Once an item's collision is active, that item's movement through the environment is limited to its free space only. See the example below. Note that when moving the object, whenever it encounters another item in its path, it ''brakes'', causing a collision with the object.
Collision disabled: when collision is disabled, the movement of the item through the environment is freer. It can now be moved in all directions, including overlapping objects in its path.
