TsgDXFViewport
Unit: DXFConv
Description
This class defines an area in paper space that contains a view of model space. Viewports are treated as drawing objects which display views and can be moved or resized. Any entity can be the boundary of the Viewport.
Syntax
TsgDXFViewport = class(TsgDXFPenEntity)
