What is DXF?
DXF stands for Drawing Exchange Format or it is also coined as Drawing Interchange Format. It refers to an open sourced or CAD data file format which was created and developed in 1982 by Autodesk. The main purpose of this system is to enable the interoperability of the data. This is applicable to both 2D and 3D drawings for images between programs in the internet and AutoCAD.
Since its advent in the computer world in 1982, DXF has been a great part of AutoCAD 1.0. The main goal and purpose of the system is actually to give an exact data representation of the native file format of AutoCAD. Nevertheless, since its introduction, the system has definitely undergone several updates and modifications. The latest version of the system is Release 14 which supports binary forms and ASCII. It is a good thing that whatever files created and developed using the earlier versions could still be accessed or opened with the new and latest releases.
To understand DXF more, it helps you know about the different components of its sections. It basically includes the Header which has all the general information contents specifically about the drawings. It also includes the Classes which contains the information that the application defines. Blocks are components which have the description of the entities while the Entities store all the drawing entities of the file. For data and information of non graphical objects, you could access the Objects section. To preview the image, you could access the Thumb-Nail-Image.
Take note that every section requires code associated with the value needed to access the section. In most computer aided design or CAD, drawings, you could easily represent it with DXF files. It could also convert PS/PDF files to better handle the contour information along with the vector graphics, 3D supported objects and text fonts.
