Causes: The DWG file format is a compressed format, while DXF files are an ASCII text format. These files will always be larger than the originating DWG.
Why are my DXF files so big?
In general, the newer DXF formats have more overhead, meaning that the files eat up more storage. Consider this simple 8 inch square, drawn in QCad. Let’s see how the various DXF versions affect the size of the file when it’s saved. When saving as an R12 DXF in QCad, the file size is 17,392 bytes.
What is better DXF or DWG?
DWG files are more compact than DXF files and can also store a greater variety of files. DWG files use binary code — that is, a computer processing language made of zeroes and ones. DXF files use text-based coding (ASCII). … This makes DXF larger but also more compatible with other programs.

When should I use DXF files?
Many engineers, designers, and architects use the DXF file format for 2D and 3D drawings during product design. DXF files are supported in several 3D applications, but they’re more commonly used to share designs across different CAD programs.
Is a DXF file 2D?
Compared to the most popular file format for 3D printing, STL, both the DXF and STL format are very compatible with third-party software. The main difference between these two formats is that STL files are 3D model files, while DXF are 2D or 3D drawings.
Can AutoCAD use DXF?
DXF files can be imported into CAD programs, such as AutoCAD. 1. Prior to importing your file, adjust your units by typing in UNITS and change the length type to Decimal and the Insertion scale units to Unitless.
