Render layers
GroupDocs.Viewer renders all layers of the CAD drawing by default. To render specific layers you can set the layers that you want to render by adding them into the CadOptions.Layers property of HtmlViewOptions (or PngViewOptions, or JpgViewOptions, orPdfViewOptions) class.
The following code sample shows how to render a specific layer of a CAD drawing.
using (Viewer viewer = new Viewer("sample.dwg"))
{
HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();
viewOptions.CadOptions.Layers = new List<Layer>
{
new Layer("TRIANGLE"),
new Layer("QUADRANT")
};
viewer.View(viewOptions);
}
