Design of interaction of CAD platform

With the increasing popularity of CAD software, the interactive experience on the software is increasingly demanding. Therefore, a well-designed interaction solution is of great significance. By examining the history of human-computer interaction, the concept of "people-oriented" is emphasized. Through the introduction of AutoCAD and SolidWorks, this article summarizes the basic interaction mode of CAD software, and point out that some of the current problem. These papers propose an interactive design solution through “object-oriented approach”. Command, tool and other core objects are defined; Command organization, command control, and other major processes are clarified in the solution.
