Substitute Font in DWG with Aspose.CAD for Java

Introduction

In the dynamic realm of Computer-Aided Design (CAD), enhancing the visual appeal of drawings is often crucial. One effective way to achieve this is by substituting fonts within DWG files. Aspose.CAD for Java emerges as a powerful tool in this domain, providing a seamless solution to font substitution. In this tutorial, we’ll walk through the process step by step, demonstrating how to substitute fonts in a DWG file using Aspose.CAD for Java.

Prerequisites

Before delving into the font substitution magic, ensure you have the following prerequisites in place:

• Java Environment: Make sure you have a functional Java environment installed on your machine.
• Aspose.CAD for Java Library: Download and install the Aspose.CAD library from the website.
• Sample DWG File: Have a DWG file ready for experimentation. If you don’t have one, you can find samples on various CAD resources.

Import Namespaces

In your Java project, import the necessary namespaces to access Aspose.CAD functionalities. This step is crucial for establishing a connection with the Aspose.CAD library.

import com.aspose.cad.Image;

import com.aspose.cad.fileformats.cad.CadImage;
import com.aspose.cad.fileformats.cad.cadtables.CadStyleTableObject;

Font Substitution in DWG

Step 1: Load Your DWG File

Begin by loading the DWG file into your Java project using the Aspose.CAD library.

// The path to the resource directory.
String dataDir = "Your Document Directory" + "CADConversion/";

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

Step 2: Iterate Over Styles

Iterate over the styles within the CAD drawing using a loop. This allows you to access and modify individual styles.

for(Object style : cadImage.getStyles())
{
    // Set the font name
    ((com.aspose.cad.fileformats.cad.cadtables.CadStyleTableObject)style).setPrimaryFontName("Arial");
}

Step 3: Save Changes

After substituting the fonts, ensure to save the changes to your DWG file.

cadImage.save(dataDir + "output.dwg", new DwgOptions());

By following these steps, you successfully substitute fonts in a DWG file, transforming the visual presentation of your CAD document.

Conclusion

Incorporating font substitutions in your CAD drawings brings a new dimension to visual aesthetics. Aspose.CAD for Java simplifies this process, providing a user-friendly interface for font manipulation within DWG files. Experiment with different fonts to achieve the desired impact on your designs.
