This attribute allows item collision to be forced. Since aggregated modules are not recognized in the environment, it is necessary to apply this attribute for the collision to be forced.
With a value of True, the collision of items with other items with the same attribute will be forced.
In the registration of this attribute, its default setting defines that it is automatically created (in a hidden way) for all entities (property Automatic Creation) with default value False, that is, the attribute is applied in all modules but without forcing the collision, since it is not necessary in modules that are not aggregated. If you need to define that the aggregate should force collision, you need to apply the attribute in the module and change its value to True.
Side of counters and cabinets that suffer joints. As the sides are aggregated from the counters and cabinets, so that the collision between the sides occurs, it is necessary to apply this attribute with a value of True.
Through the images below, it is possible to notice that on the left, with the ForceCollisionTest attribute with a value of False, or not even applied (due to its default value - False), the sides are not recognized for collision and, therefore, the junction does not occur. On the right, it is possible to notice that the sides are joined after application of the ForceCollisionTest attribute with True value, since the sides start to be recognized and suffer the collision, being able to suffer the joint (if configured correctly).
