TsgDXFPolyline
Unit: DXFConv
Description
This class defines a polyline (entity POLYLINE). This object is a 2D/3D line composed of line and arc (bulges) segments. Polyline is specified by an array of Vertexes (use Entity property to obtain an instance of TsgDXFVertex class). Polyline can be Open or Closed (see Closed property).
Syntax
TsgDXFPolyline = class(TsgCADBasePolyline )
