OpenDCL 4.0 Debuts

OpenDCL 4.0 has finally been released. If you’re not familiar with OpenDCL, check it out at, or on SourceForge at

OpenDCL, based on the original commercial ObjectDCL software by Chad Wanless, is a modern replacement for the old DCL dialog control language in AutoCAD. The current OpenDCL Runtime supports AutoCAD 2002 through 2008 (except AutoCAD 2008 x64). It is designed to give AutoCAD end users and AutoLISP application developers a simple yet powerful way to design and use rich user interfaces in their applications.

The goal for version 4.0 was to get it stable and fix all the bugs, with minimal new feature development. OpenDCL 4.1 will add support for AutoCAD 2008 x64. After that we will start working on localized language versions, and adding new features.

OpenDCL is licensed under the GNU General Public License (GNU GPL) open source license, completely free to use, and source code is available on SourceForge.
