Parametric Drawing of Bearing Engineering Drawings based on Auto LISP

摘要

As the secondary development language of Auto CAD,Auto LISP is widely used in the standard rendering of various complex graphics.This method uses Auto LISP as a tool to select and draw three common bearings according to the matched spindles.This paper describes the key steps of bearing parametric drawing and implementation process in detail.This developed program simplifies the drawing process,reduces the repetitive work in the design,and improves the efficiency of drawing.
