• Aspose.CAD for Java Library: Ensure that you have the Aspose.CAD library for Java installed. You can download it from the website.

• Java Development Environment: Set up a Java development environment on your machine.

Import Namespaces

In your Java application, you need to import the necessary namespaces to use Aspose.CAD. Add the following lines at the beginning of your Java file:

import com.aspose.cad.Image;

import com.aspose.cad.fileformats.cad.CadImage;
import com.aspose.cad.fileformats.cad.CadLayoutDictionary;
import com.aspose.cad.fileformats.cad.cadobjects.CadLayout;

Step 1: Set up Your Document Directory

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

Ensure to replace “Your Document Directory” with the path to the directory where your CAD files are stored.

Step 2: Load the DWG File

String sourceFilePath = dataDir + "conic_pyramid.dxf";
Image image = Image.load(sourceFilePath);
CadImage cadImage = (CadImage)image;

Load the DWG file using the specified file path.

Step 3: Get Layouts and Print Names

CadLayoutDictionary layouts = cadImage.getLayouts();
for (CadLayout layout : layouts.getValues())
{
    System.out.println("Layout " + layout.getLayoutName());
}

Retrieve the layouts from the DWG file and print their names to the console.
