TsgDXFConverter

Description

The TsgDXFConverter class provides the list of entities (made on the TsgDXFEntity base), loaded from a CAD file. This is the manager class. The TsgDXFConverter class implements the main operations of the import.

This class is intended for:

• Displaying DXF/DWF/DWG/HPGL/HPGL2/SVG/CGM files on a screen that marketed in TsgCADImage, TsgCADdxfImage, TsgDWFImage, TsgDWGImage, TsgHPGLImage, TsgSVGImage, TsgCGMImage.
• Accessing to the section of elements, for what indexed properties Tables, Blocks and Entities are used

Syntax

TsgDXFConverter = class;
