The majority of formats require the same two steps for visualization on a GXY view. To visualize AutoCAD DWG and DXF data:
-
Decode the data into an
ILcdModel
using anILcdModelDecoder
. -
Create an
ILcdGXYLayer
for theILcdModel
and add it to theILcdGXYView
.
//First create the model
ILcdModelDecoder decoder =
new TLcdCompositeModelDecoder(TLcdServiceLoader.getInstance(ILcdModelDecoder.class));
ILcdModel model = decoder.decode("Data/Dwg/world.dwg");
//Create a layer for the model with default styling
ILcdGXYLayer layer = new TLcdDWGGXYLayerFactory().createGXYLayer(model);
//Wrap the layer with an async layer wrapper to ensure
//that the view remains responsive while data is being painted
layer = ILcdGXYAsynchronousLayerWrapper.create(layer);
//Add the async layer to the GXY view (an ILcdGXYView)
view.addGXYLayer(layer);
This results in a AutoCAD DWG and DXF layer with default styling. See Visualizing Vector Data for more information about visualizing and styling vector data.
