How to create a layer for each AutoCAD layer ?

When using the TLcdDWGModelDecoder the whole DWG or DFX file is decoded into a single model.

If you want to visualize each AutoCAD layer in a different layer on your map, you should use the TLcdDWGModelListDecoder instead. This model decoder will create a single model per AutoCAD layer, making it easy to create a single map layer for each AutoCAD layer.
