    Load CAD document with options

    GroupDocs.Conversion provides CadLoadOptions to give you control over how the source CAD document will be processed. The following options could be set:

    • setFormat allows you to set the source document format explicitly with this property. Available options are: Dxf, Dwg, Dgn, Dwf, Stl, Ifc, Plt, Igs, Dwt.
    • setWidth sets the desired page width.
    • setHeight sets the desired page height.
    • setLayoutNames specifies which CAD layout to be converted.

    Specify layouts to be converted

    The following code snippet shows how to convert a CAD document and convert only certain layouts:

    const outputPath = "ConvertCadAndSpecifyLayouts.pdf"
  
const loadOptions = new groupdocs.conversion.CadLoadOptions()
loadOptions.setLayoutNames(["Layout1", "Layout3"]);
const converter = new groupdocs.conversion.Converter("with_layers_and_layouts.dwg", () => loadOptions);

const convertOptions = new groupdocs.conversion.PdfConvertOptions()
console.log(`Cad document converted successfully to ${outputPath} (cad & specify layouts)`)
converter.convert(outputPath, convertOptions)

    Specify width and height

    The following code snippet shows how to convert a CAD document and specify the width and height:

    const outputPath = "convertCadAndSpecifyWidthAndHeight.tiff"

const loadOptions = new groupdocs.conversion.CadLoadOptions()
loadOptions.setWidth(1920);
loadOptions.setHeight(1080);

const converter = new groupdocs.conversion.Converter("with_layers_and_layouts.dwg", () => loadOptions);

const convertOptions = new groupdocs.conversion.ImageConvertOptions();
convertOptions.setFormat_ConvertOptions_New(groupdocs.conversion.ImageFileType.Tiff);

console.log(`Cad document converted successfully to ${outputPath} (cad & specify width and height)`)
converter.convert(outputPath, convertOptions)
