TsgDXFLayer
Unit: DXFConv
Description
This class defines an item of the LAYER table of the DXF file.
A layer assignment is just an attribute of a DXF entity, it’s not an entity container, the entities are stored in layouts and blocks and the assigned layer is not important for that.
Deleting a layer entry does not delete the entities which reference this layer!
Syntax
TsgDXFLayer = class(TsgDXFPenTableItem)
