DWG and DGN File Compatibility

autocad dgn intellicad

CMS IntelliCAD uses the platform from the Open Design Alliance for its Autodesk DWG™ format compatibility. The latest versions of CMS IntelliCAD edits, and saves any existing .dwg files saved in numerous versions, including Version 2.5 through 2018, without conversion or data loss. Like AutoCAD® software and AutoCAD LT® software, CMS IntelliCAD® uses .dwg file as its native file format. That makes CMS IntelliCAD® 9.x more compatible with older versions of AutoCAD® software than AutoCAD® software itself!
