M4 PERSONAL is the powerful free 2D/3D CAD package
M4 PERSONAL has been used worldwide for many years to quickly create 2D drawings for home projects, and by hobbyists to produce 3D models ready for 3D printing. Due to its versatile CAD functionality, and its ability to edit DWG and DXF files, the software has also become established in many small companies. When used by companies, finished drawings are published for commercial use for a small fee e.g. converted to PDF or DXF format. This pay-per-result approach means that there is no cost to purchase the software, only for drawings that are used commercially.
