What MEDUSA4 (now M4 DRAFTING) is
MEDUSA4, now M4 DRAFTING, is a Windows 2D/3D CAD and design-automation suite with parametric modelling and sheet-metal tools. Packages include Drafting, Premium, and Ultimate, with add-on modules. Capabilities cover 2D drawing, macros and programming, dynamic geometry editing, parametric symbols and parts libraries, basic and advanced 3D modelling, terrain modelling, sheet-metal design, and P&ID design. The software can open, view, edit, and convert DWG and DXF files into 3D models. It imports DWG, DXF, DGN, STEP, IGES, VRML, VDA, and STL, and exports PDF. Interfaces are described for ERP, PDM, and PLM systems. The 14-day trial allows DXF/DWG import but not export, and trial prints carry a watermark. Single-user and network licences are available.
