TsgDXFLayout
Unit: DXFConv
Description
Encapsulates the LAYOUT object of OBJECTS section. LAYOUT is a page of entities representation. DWG and DXF have Model (it is also TsgDXFLayout) and Layouts � the last can have viewports. Layouts in HPGL are pages. VIEWPORT.
Syntax
TsgDXFLayout = class(TsgDXFObjectEntity)
