How do I open a DXF file in AutoCAD
A file with the extension .DXF is a Drawing Exchange Format file developed by Autodesk as a universal format for storing CAD models. The idea is that if the file format is supported in different 3D modeling programs, they can all easily import/export the same documents.
This format, also known as Drawing Interchange Format, is similar to the AutoCAD Drawing Database file format that uses the DWG file extension. However, DXF files are more widely used in CAD programs because they can exist in a text-based format, making them naturally easier to implement in these types of applications.
DWF files are similar, but are used for sharing files online or through a free viewer program, while DXF is intended for interoperability.
