Render single layout

GroupDocs.Viewer renders Model layout of CAD drawing by default. To render specific layout from a CAD drawing the API providesCadOptions.LayoutName property of HtmlViewOptions (or JpgViewOptions, or PngViewOptions, or PdfViewOptions) class. When this property is set, CadOptions.RenderLayouts property will be ignored.

Following are the steps to render specific layout in CAD drawing.

• Create HtmlViewOptions object.
• Set CadOptions.LayoutName of HtmlViewOptions.
• Call View method.

The following code sample shows how to render a specific layout.

            using (Viewer viewer = new Viewer("sample.dwg"))
            {
                HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();
                viewOptions.CadOptions.LayoutName = "Model";
                viewer.View(viewOptions);
            }
