Taking the non-standard screws as an example,we discuss two methods of generating configurations in SolidWorks by using the design table,and at the same time,we discuss two methods of inserting them into the assembly,and compare the advantages and disadvantages of these methods.Finally,a better method of self-built standard library:use the feature configuration function to create a new design table and generate configurations,and then added to the design library.Practice has proved that:the method of self-built standard library,editing,modification is convenient,can achieve one-key assembly,improve the efficiency of the design.
