Prerequisites

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

• Java Development Environment: Ensure you have a Java development environment set up on your system.
• Aspose.CAD for Java Library: Download and install the Aspose.CAD for Java library from the download link.
• Document Directory: Create a directory to store your CAD files for easy access.

Import Namespaces

In your Java project, import the necessary namespaces to utilize the functionality of Aspose.CAD for Java:

import com.aspose.cad.Image;

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

Now, let’s break down the example code into multiple steps:

Step 1: Set the Resource Directory Path

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

Ensure you replace "Your Document Directory" with the path to your document directory.

Step 2: Load the CAD Image

String srcFile = dataDir + "conic_pyramid.dxf";
Image cadImage = Image.load(srcFile);

Replace "conic_pyramid.dxf" with the name of your AutoCAD file.

Step 3: Set Rasterization Options

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.setPageWidth(500);
rasterizationOptions.setPageHeight(500);
// rasterizationOptions.setTypeOfEntities(TypeOfEntities.Entities3D);

rasterizationOptions.setLayouts(new String[] {"Model"});

Adjust the width, height, and layout settings based on your preferences.

Step 4: Configure PDF Options

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

Set up PDF options, including vector rasterization settings.

Step 5: Save the PDF

cadImage.save(dataDir + "Export3DImagestoPDF_out_.pdf", pdfOptions);

Specify the output directory and file name for the generated PDF.
