Help keep OpenDCL moving forward!

August 19th, 2013

OpenDCL is and always will be FREE!
However times are tough and it’s getting harder to spend time on a project when there’s no compensation for it. Our lead developer, Owen Wengerd of ManuSoft, has been supporting the OpenDCL community for years now without ever receiving a single penny for his monumental contribution. I, Barry Ralphs, have also been footing the bill to keep the OpenDCL web site up and running. If you’d like to help keep OpenDCL moving forward, please go to the following URL to make a contribution/donation.


AutoCAD 2013 Support

March 28th, 2012

I’ve just released OpenDCL 7.0 Alpha 4 with support for AutoCAD 2013. Even though this is an alpha release, not much development work has been done since OpenDCL 6 was released, so this is a very stable pre-release build that can be safely used in production if needed.

OpenDCL 6 Released

August 5th, 2011

OpenDCL 6 has now been formally released. In addition to many internal improvements, OpenDCL 6 adds support for the Bricscad platform on Windows. Use the Download link to get the current OpenDCL files.

End Users

  • If you are already using a pre-release build of OpenDCL 6 runtime, then you should upgrade immediately to the released build.
  • If you are still using an older runtime version, then you should not install the latest runtime version immediately. The upgrade path from OpenDCL 5 is designed to be seamless and problem-free for end users, however you should wait for developers to complete testing on the new runtime version before upgrading.


  • You should now be developing, testing, and supporting your application on the OpenDCL 6 runtime architecture.
  • You should make an effort to test and support your application on the Bricscad for Windows platform.
  • You should not assume end users will continue using the version of OpenDCL Runtime shipped with your application.

Bricsys Developer Conference Followup

June 12th, 2010

I expect a few new OpenDCL developers as a result of my presentation at the Bricsys developer conference. My presentation was followed by Coert van den Broek demonstrating his OpenDCL based CADTroon application running in Bricscad.
My presentation got off to a rocky start when the projector refused to work. I had to wing it for a while until the projector suddenly decided to work again. Some topics didn’t get covered as a result, but it all worked out in the end.
Bricscad support has been a major focus in OpenDCL 6, and I expect OpenDCL 6 to finally enter the beta phase when the next public Bricscad update is released. Bricsys recognizes the importance of OpenDCL, and I have every reason to believe that they will continue to support our work.
