Open CAD Studio October 2026 Development Highlights

By

Open CAD Studio development does not seem to be slowing down. During the past month, several important features were added and many bugs were fixed. Thanks to the weekly release schedule, Open CAD Studio moves forward very fast.


Some of the new features introduced last month include:

  • First implementation of DGN support added.
  • First implementation of DWF support added.
  • Moved parametric modeling tools to independent ribbon tab. These tools enable users to constrain the geometry to create parametric models.
  • New external reference attachment dialogue. This enables complex setup of XREF during the first insertion.
  • New PDF attach dialogue, with all the needed import options setup. PDF is now imported as a vector geometry and enables snapping and turning PDF layers on and off.
  • New XCLIP tool for clipping external references, PDF and raster image attachments.
  • Introduction of the table tool.
  • Basic node based graph added. This is a tool similar to Dynamo in Revit.
  • Improvements to the MCP server workflows.
  • Improvements to the annotation system.
  • Compatibility improvements.
  • Availability of Open CAD Studio on FlatPark, a community-run repository hub for Linux desktop applications packaged using Flatpak.
  • Many other improvements and bug fixes.

Open CAD Studio is a free, open source native DWG authoring tool. It is available for Windows, macOS, Linux and also as a web application version.
