Indeed, both CAD software are simply using the same DWG file format. There is no conversion and therefore no loss of data when files are shared between IIACAD and AutoCAD® users. Other file formats supported by both software include DXF, DWS and configuration files such as .ctb, .stb, .shx, .mln, .dim or .pcx (aka .pc3 in AutoCAD®). Both software are also able to import or attach DGN files, export to PDF and convert PDF back to DWG.
Users who are familiar with AutoCAD® can instantly switch to IIACAD without additional training. Users transitioning from AutoCAD® can even use the same keyboard shortcuts and commands given that aliases have been defined to match the IIACAD commands when they are different. The user interface is also significantly the same and we have added an alternative ribbon workspace named “CAD General” to facilitate the switch for users coming from AutoCAD®.
