The DXFReader.framework provides classes for reading a standard ASCII
text DXF file into an array of "entities" (to use the AutoCAD term) that can be
used by a program implementing this framework.
The BBDXFModel object is the main class. It includes methods for reading and parsing the DXF file. The BBDXFEntity class and its subclasses (BBDXFEntityLine, Polyline, Arc, etc) follow the data structure established by AutoCAD in their definition of the DXF file standard. One of these custom objects is created for each entity contained in the DXF file for the types that are supported by this framework. The framework is developed following the AutoCAD 2009 DXF standard. The DXF standard is generally backward compatible with previous versions of the AutoCAD DXF standard, but this compatiblity has not been extensively tested. A standard DXF file output by AutoCAD or a similar CAD program contains a large quantity of information. With this preliminary version (0.1) only the following entity types are supported.
