  "formatDescription": "ASCII DXF format is the ASCII encoded variant of the Drawing Interchange File Format, an exchange format for vector graphics developed by AutoDesk. They are probably the widely-used formats for exchanging vector data, and have become a de-facto industry standard. The format is owned by AutoDesk and typically changes with each release of their AutoCAD family of products. DXF files contain a tagged representation of the vector data. The structure comprises a Header section, followed by sections containing data on Classes, Tables, Blocks, Entities and, optionally, thumbnail images. Each section contains a series of data elements. each preceded by a group code tag, which indicates the type of data element. ASCII DXF version 9 is the version of the format associated with Release 9 of the AutoCAD family of software products.",
