Implementation of Parametric Drawing Based on AutoLISP Language

When drawing mechanical parts drawings, it often encounters the cumbersome work of drawing common parts such as standard parts and center holes. The block operation command BLOCK and the block write command WBLOCK provided in AutoCAD can write a common graphic into a block, and then use the INSERT command to insert, so as to avoid repeatedly drawing a common graphic, but this method can only be pressed. The scale scales the graph and cannot be parameterized. The so-called parametric drawing is to associate the graphic in the drawing with a set of parameters, and the constraint conditions represented by the set of parameters determine the corresponding component graphic, that is, after generating the graphic according to the parameter or modifying the parameters of the existing graphic. Graphic update. This article describes the use of AutoLISP language in AutoCAD software.
