TsgDXFGroup

Unit: DXFConv

This is base class for all the entities that include child entities: POLYLINE, BLOCK, etc.

`Color`	The property gets or sets entity color.
`ColorCAD`	The property gets or sets a color for drawing entities.
`Complex`	The property determines whether a entity is populated with child entities.
`Converter`	The property returns the `TsgDXFConverter` class object.
`Count`	The property indicates the total number of child entities.
`Entities`	The property lists all child entities.
`EntType`	The property indicates type of an entity.
`Handle`	The property is used for finding entity links.
`Layer`	The property points to layer, containing given primitive if this layer is given.
`LineType`	The property sets and gets line type for an entity.
`LineTypeScale`	The property sets and gets the `Linetype` scale.
`LineWeight`	The property sets or gets line weight in millimeters.
`PaperSpace`	The property indicates Model Space and Paper Space entity segregation.
`SrcEnd`	The property indicates end position of the entity description in the source CAD file.
`SrcStart`	The property indicates start position of the entity description in the source CAD file.
`Visibility`	The property sets and gets entities visibility.
`Visible`	The property determines whether the component appears onscreen.

Methods	Description
`Clear`	The method deletes all child entities.
