基于CASS平台的快捷命令定制方法研究

Research on Shortcut Command Customization Method Based on CASS Platform

CASS是基于AutoCAD开发的一款商用数字化绘图平台,仍然保留着与AutoCAD相同的命令式绘图方式。在CASS平台上,每一类要素都有一个6位数的CASS码,用户在命令行执行根绘图命令「DD」后输入CASS码即可绘制相应的要素。通过对CASS平台绘图方式、AutoCAD命令重定义机制及AutoLISP语言的深入研究,使用AutoCAD提供的ARX.NET二次开发接口,开发了新的快捷命令定制工具,能够对CASS绘图代码或已有的命令进行重新封装,解决了CASS码输入不便及记忆量较大的问题,对提升绘图效率具有明显效果。

CASS is a commercial digital drawing platform developed based on AutoCAD,which still retains the same command—based drawing method as AutoCAD.On the CASS platform,each clement has a 6—digit CASS code.Users can draw the corresponding element by entering the CASS code after executing the root drawing command「DD」in the command line.Through in—depth research on the drawing method of CASS platform,AutoCAD command redefinition mechanism and AutoLISP language,using the ARX.NET secondary development interface provided by AutoCAD,a new shortcut command customization tool was developed,which can modify CASS drawing code or existing commands.Repackaging solves the problem of inconvenient CASS code input and large memory capacity,and has a significant effect on improving drawing efficiency.
