The invention relates to a Boolean union operation method of a three-dimensional planar entity. The method is characterized in that for each plane in an entity A, the plane is stored when the plane isbeyond an entity B completely; if the plane and the plane of the entity B are in a same-direction and coplane manner and are not inner loop surfaces, two-dimensional Boolean union operation is carried out on the two planes and the operation result is stored; if the plane is not in the above-mentioned condition, the plane cuts off the entity B to obtain a profile polygon, two-dimensional Boolean subtraction operation is carried out on the plane and the profile polygon and the operation result is stored; the entity A and the entity B are switched and the same treatment is carried out on the entities respectively; and post treatment including repeated plane deletion, suspension plane deletion, and plane merging is carried out on the stored results to obtain a Boolean union operation result of the entity A and the entity B. The method has advantages of being simple, being easy to implement, having rigorous algorithm logic, having perfect geometric completeness, and having low arithmetic operation load and can be applied to three-dimensional entity modeling in fields of CAD, CAM, CAE, computer animation, virtual reality and 3D printing.
