All dwg objects that are drawing entities and that can be converted to a fmap geometry implements this interface.
All dwg drawing entities that could have 3D data must implement this interface, to test if they have certainly a third dimension
A block is a composite entity in autocad (it is a drawing entity, and it contains drawing entities) Currently we have found DwgBlock and DwgBlockHeaders as start of a block.
All dwg drawing entities that need to compute an extrussion before draw them must implement this interface.
If a DwgObject (dwg drawing entity) is a kind of polyline must implements this interface TODO Ahora mismo pasamos dwgObjs.
Base interface for all DWG vertices.
Clase que engloba m�todos para trabajar con bytes.
Entry in the CLASSES section of a dwg file.
The DwgFile class provides a revision-neutral interface for reading and handling DWG files Reading methods are useful for reading DWG files, and handling methods like calculateDwgPolylines() are useful for handling more complex objects in the DWG file
The DwgHeader class implements the Header of a DWG file
The DwgObject class represents a DWG object
Factory that creates dwg entities from its code (int value).
The DwgObjectOffset class is useful to store the handle of an object with its offset in the DWG file
The DwgSectionOffset class is useful to store the key of a DWG section with its seek (or offset) and with its size
The DwgUtil class contains the essential set of functions for reading bitstreams in DWG files
