In this tutorial, we’ll explore how to utilize Aspose.CAD for Java to effortlessly convert DWG files to compliant PDFs, ensuring adherence to PDF/A1a and PDF/A1b standards.

Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites in place:

• Java Development Environment: Make sure you have a working Java development environment set up on your system.
• Aspose.CAD Library: Download and install the Aspose.CAD library for Java from the download link.
• Document Directory: Create a directory to store your DWG drawings.

Import Namespaces

In your Java project, import the necessary namespaces to access the functionalities of Aspose.CAD. Add the following lines at the beginning of your Java file:

import com.aspose.cad.Image;

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

Step 1: Set the Resource Directory

Define the path to your resource directory where the DWG drawings are stored.

String dataDir = "Your Document Directory" + "DWGDrawings/";

Step 2: Load the DWG File

Load the DWG file using the Aspose.CAD library.

String srcFile = dataDir + "Bottom_plate.dwg";
Image objImage = Image.load(srcFile);

Step 3: Create PDF Options

Create an instance of PdfOptions and set the vector rasterization options.

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

Step 4: Set Core PDF Options

Set the core PDF options, specifying the compliance standard (PDF/A1a or PDF/A1b).

pdfOptions.setCorePdfOptions(new PdfDocumentOptions());
pdfOptions.getCorePdfOptions().setCompliance(PdfCompliance.PdfA1a);

Step 5: Save PDF with Compliance A1a

Save the PDF file with compliance A1a.

objImage.save(dataDir + "Saved1.pdf", pdfOptions);

Step 6: Change Compliance to A1b

Change the compliance to PDF/A1b and save the PDF.

pdfOptions.getCorePdfOptions().setCompliance(PdfCompliance.PdfA1b);
objImage.save(dataDir + "Saved.pdf", pdfOptions);

Repeat these steps for each DWG file you want to convert.

Conclusion

In conclusion, Aspose.CAD for Java provides a robust solution for converting DWG files to compliance PDFs. By following this step-by-step guide, you can streamline the conversion process and ensure that your documents adhere to industry standards.
