Both solutions use the same DWG 2018-2022 file format natively. There is no conversion and therefore no loss of data when files are shared between ARES Commander and AutoCAD users. Other file formats supported include DXF, DWS (Drawing standards), DST (Sheet Sets), and configuration files such as .ctb, .stb, .shx, .mln, .dim or .pcx (aka .pc3 in AutoCAD). Both are also able to import or attach DGN files, export to PDF and convert PDF back to DWG.
