Research on modeling of superimposed parts based on solidworks

The article explains the meaning of the superimposed feature from different aspects, analyzes the shape composition and modeling method of superimposed features through examples, summarizes the modeling rules: 1) According to the projection relationship, the wire frame is separated. Analyze the positional relationship of the wire frame of each surface according to the view projection, determine the corresponding surface of the wire frame, and clarify the shape of the boss. This step is the key to determining whether the modeling can be completed successfully. 2) Visualize the object, determine its position and sequence. Through the method of shape analysis and dimension, the position and superimposed order of the boss are determined, and the shape features after superposition are clear. This step is an important basis for rapid modeling. 3) Think over, the shape and the view are checked repeatedly to ensure the position of the shape features is clear, the shape is accurate and the structure is complete.
