With the rapid development of automobiles and light industry, mold design and manufacturing has been widely concerned by people and has formed an industry. Mold manufacturing has evolved from traditional machining to two-dimensional manual programming CNC machining to today's CAD/CAM integrated manufacturing; mold design has also evolved from manual drawing, 2D computer graphics to 3D computer-aided design.

The biggest difficulty for the mold designer in drawing the mold set is to remove the part drawing in the drawing, that is, to disassemble the part graphic into the upper and lower parts of the group frame according to the attribute bubble chart of the part in the group drawing. The mold designer's approach is to find the layer of the part graphic represented by the attribute bubble, and then find the figure of the corresponding part, and then copy the corresponding part of the part to the upper and lower parts of the group diagram. This method of removing the parts and drawings, it takes a lot of time to find the graphics corresponding to the bubble of the assembled picture in the figure of the removed parts, and for thousands of parts and molds, there is a great possibility of detachment, and the parts are removed. The accuracy of the graph is difficult to guarantee.

In view of the above, it is necessary to provide a part drawing system and method, which can accurately remove the part drawing to the upper and lower parts of the assembled frame, and can improve the efficiency of the drawing.
