TsgDXFBlock
Unit: DXFConv
Description
This class defines an item of BLOCK table of a CAD file. A block is a collection of objects which associated together to form a single object, or block definition. Use Entities property to obtain an entity in the collection.
Syntax
TsgDXFBlock = class(TsgDXFGroup)
