How to get CAD layers and layouts
Retrieving layers and layouts
GroupDocs.Viewer provides additional information about CAD drawings such as list of layouts and layers when calling getViewInfo(…) method. To retrieve view information for CAD drawing call getViewInfo(…) method and cast output result to CadViewInfo type.
Following example demonstrates how to retrieve view information for CAD drawing.
Viewer viewer = new Viewer("sample.dwg");
ViewInfoOptions viewInfoOptions = ViewInfoOptions.forHtmlView();
CadViewInfo viewInfo = (CadViewInfo) viewer.getViewInfo(viewInfoOptions);
System.out.println("File type: " + viewInfo.getFileType());
System.out.println("Pages count: " + viewInfo.getPages().size());
for (Layout layout : viewInfo.getLayouts()) {
System.out.println(layout);
}
for (Layer layer : viewInfo.getLayers()) {
System.out.println(layer);
}
