What is DXF file format?
- DXF ( Drawing Exchange Format ) is a vector file format most widely used and recommended for 2-D designs used in CAD.
 - It was created by AutoDesk as an open standard, So it is supported by every CAD program in the market.
 
What programs can we use to view/edit DXF files?
- We can use a range of programs to view/edit DFX files.

Numerical representation of DXF
ASCII DFX file:
The ASCII DXF file is a complete representation of a drawing in ASCII text form.  Data is represented with numbers and strings of text that you can easily interpret using the specification document. 
Binary ASCII file:
The binary DXF is a smaller file that is faster to work with. Binary files are usually 25% smaller than ASCII file and can be processed almost 5 times faster. 
Color Depth:
The DXF file format supports 8-bit colour depths (256 colours).
