NX Assembly Clearance reports the following types of interferences:
Soft Interference - The minimum distance between the objects is less than or equal to the clearance zone. Objects that are closer than this distance are reported as interference, even if they do not touch.
Touching Interference - Objects are touching but do not intersect each other.
Hard Interference - Objects intersect each other.
Containment Interference - One object is completely contained within another object.
