However, the standard, plain DXF file for pattern-making CAD programs is unreliable for 3D clothing simulation systems. Standard DXF pattern format is similar to Auto CAD Drawing Database file format that uses DWG file extension (drawing database file that stores metadata and 2D or 3D vector image drawings). Standard DXF is often used to exchange drawing files created in different CAD systems. The difference between a standard DXF file and ASTM/AAMA DXF file Most likely, you will encounter the following types of DXF pattern files and block patterns: Most pattern-making CAD systems can import and export cutting patterns for clothing in DXF format, making it easier to communicate 2D pattern information among different CAD systems. Since DXF drawings do not include dimensions, the user must indicate the unit used to create the drawing when converting the original CAD file to a DXF file.
However, DXF files are primarily used for 2D data exchange among different CAD programs. DXF files are vector graphic files that store 2D drawings. It was developed by Autodesk, creator of the well-known AutoCAD, to enable interoperability between AutoCAD and other programs. DXF (Drawing exchange format) is the most common file format for sharing among various CAD programs.
