Open Design Alliance Releases Teigha 4.2.4—Support for Autodesk ReCap Files

ODA updates Teigha SDK technologies to version 4.2.2.


In further news from the ODA, the open consortium group has released Teigha 4.2.2 to developers in early January. The release adds support for reading and visualizing Autodesk ReCap™ point cloud files (.rcs) which are commonly used to attach point cloud data to .dwg files.

“Incremental save significantly improves the speed of saving to .dwg,” commented Neil Peterson, ODA President. “It’s an important feature for developers of CAD editors and other applications that save files frequently.”

Teigha Gets Beta Support for Persistent Transactions

The new support of persistent transactions means ODA’s developer members can begin to test this new technology in beta format. Persistent transactions are essentially technology that enables a complete saving of undo/redo changes to a file between sessions. The technology can be used to allow for a complete saving of the history of changes to a DWG files in a compact format. Basically, this is “history” support for DWG files.
