You can customize ProgeSOFT IntelliCAD® by adding custom programs written in any of several programming languages that run within ProgeSOFT IntelliCAD, including LISP and Solutions Development System™ (SDS). With ProgeSOFT IntelliCAD, you can run many programs originally created for use with AutoCAD. Specifically, you can use programs written entirely in AutoLISP with no modification.
ProgeSOFT IntelliCAD supports the AutoCAD dialog control language (DCL), which is used by AutoLISP functions to define the look of dialog boxes. You can use all DCL files unmodified within ProgeSOFT IntelliCAD.
To write applications in C or C++, ProgeSOFT IntelliCAD uses SDS, a C/C++ language interface compatible with the AutoCAD Development System (ADS) interface in AutoCAD.
