New for 2020
The Open Design Alliance has taken over in setting the pace for advances in the DWG file format, now that Autodesk seemingly has lost interest in its best-selling software.
At last week's online DevCon developers conference for members of the ODA, we got shovelfuls of information on what's new in DWG. It overwhelmed us journalists in attendance and so we asked for a summary list, which was promised for this week. Here it is.
PDF & DGN Import and Export
Improvements to importing PDF files into DWG databases:
- Import full lines of PDF text as MTEXT
- Import linetypes
- Support for clipped regions during import
PDF export now uses graphics caching to improve the performance in cases where multiple views of a model are exported to the same PDF file.
Microstation DGN export from a DWG database is new, so that the ODA now supports both DGN-to-DWG conversion and DWG-to-DGN conversion.
ODA’s native revision control for DWG is refactored for easier integration into real-world client applications.
The new implementation allows clients to more easily implement revision history for groups of related files, including non-DWG files.
Conversion of point cloud data to Autodesk's RCS ReCap Source format.
Automatic level of detail selection for RCS point cloud visualization supports fast visualization and manipulation of large RCS point clouds.
New VIEWSECTION, VIEWBASE, and VIEWPROJ commands create model documentation (2D) views of models. See figure.
Saving model documentation views to standard DWG files is in progress.
Precision hidden-line removal is in progress.
Boolean operations (such as union and intersection) are now supported by the ODA Solid Modeler on OdDb3dSolids in DWG database.
Visualization for OdDbGeoData objects, which includes map data from third-party providers, is now integrated with the ODA visualization framework.
