Question:
What's the relationship between the ZWCAD .dwg file and AutoCAD® .dwg file? I have some confusion about the dwg format licensing.
Answer:
For DWG file format support, we are using the technology that came from ODA, authorized by ODA legally,.
The ODA was founded in 1998 as the OpenDWG Alliance, an independent, non-profit corporation dedicated to making the .dwg file format an open, accessible standard for storage of drawing data. It was renamed the Open Design Alliance in 2002.
DWG format is no longer a proprietary format for Autodesk, ODA is committed to promoting the unified CAD format DWG, is a CAD document data exchange standard, legally compatible with AutoCAD DWG format.
Not only our ZWCAD but also other CAD platforms like BricsCAD is using the ODA platform to support the DWG format.
