Introducing OpenDCL for AutoCAD

AutoLISP programmers may remember a product named ObjectDCL, by 3rd Day Software. ObjectDCL was released as open source in the summer of 2006 by developer Chad Wanless due to his inability to continue supporting the software because of “health reasons”. At the time, many users of ObjectDCL hoped that someone would update the code to work in AutoCAD 2007. Programmer David Robison did some work to get AutoCAD 2007 supported, but the project has been languishing, almost to the point of extinction.

After being asked by several ObjectDCL users whether I could help, I decided a few weeks ago to contribute to the community by getting the original C++ code updated to support AutoCAD 2007. As I am wont to do, I’ve ended up re-architecting much of the code in the process.

The results of my work are available now at the new OpenDCL project on SourceForge. The new 4.0 release is still in the alpha testing phase. If you program in AutoLISP and want to create rich user interfaces for your applications, check it out!
