The values associated with each variable are stored as an integer, floating-point number or a string. Group code 0 refers to the start of an entity or the end of the file. For example, group code 2 is used for names, such as names of sections or names of blocks. Representation of data using group codes and valuesĮvery variable in the DXF file is associated with a group code (there are group codes ranging from 1 to 1071) each group code is used in a certain situation and contain specific types of information. In this article, I introduce the basic setup & specification of a DXF file. Its creator, AutoDesk, publishes these official file specification documents, which defines the syntax (or a set of rules) that define a DXF file. Each CAD program then interprets this set of instructions and reproduces your vector drawing. The DXF file format is a vector graphic file format, and its specification details how different drawing elements are represented. All file formats have a specification that describes how the information is encoded in the file - how bytes are arranged, how your computer loads the file and so on.
