Step 1: Set up the Project Environment

Begin by creating a Java project and ensuring that the Aspose.CAD library is correctly integrated. You can download it here.

Step 2: Import Necessary Packages

In your Java class, import the required Aspose.CAD packages to utilize the functionalities seamlessly.

import com.aspose.cad.Image;

import com.aspose.cad.imageoptions.CadRasterizationOptions;
import com.aspose.cad.imageoptions.PdfOptions;

Step 3: Load DWG File

Specify the path of your DWG file and load it into the Aspose.CAD image object.

String srcFile = dataDir + "visualization_-_conference_room.dwg";
Image image = Image.load(srcFile);

Step 4: Configure Rasterization Options

Create an instance of CadRasterizationOptions and customize its properties according to your requirements.

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.setPageWidth(1600);
rasterizationOptions.setPageHeight(1600);
// Specify desired layout name
rasterizationOptions.setLayouts(new String[] {"Layout1"});

Step 5: Set PDF Export Options

Create a PdfOptions instance and set its VectorRasterizationOptions property to the previously configured CadRasterizationOptions.

PdfOptions pdfOptions = new PdfOptions();
pdfOptions.setVectorRasterizationOptions(rasterizationOptions);

Step 6: Export DWG to PDF

Save the modified image to a PDF file, completing the conversion process.

image.save(dataDir + "ExportSpecificLayoutToPDF_out_.pdf", pdfOptions);

Conclusion

Mastering the art of exporting specific DWG layouts to PDF using Aspose.CAD for Java can significantly enhance your CAD workflow. With the provided steps, you can seamlessly integrate this functionality into your projects, ensuring precision and efficiency.
