Export DGN to PDF in Aspose.CAD for .NET

Introduction

In the world of .NET development, Aspose.CAD is a powerful library that facilitates the manipulation and conversion of CAD files. One common task developers often encounter is exporting DGN files to PDF format. In this tutorial, we’ll walk through the process step by step, using Aspose.CAD for .NET.

Prerequisites

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

• A working knowledge of C# and the .NET framework.
• Aspose.CAD for .NET library installed. You can download it here.
• A sample DGN file, for instance, “Nikon_D90_Camera.dgn” for this tutorial.

Import Namespaces

In your C# project, begin by importing the necessary namespaces:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Aspose.CAD;

Step 1: Load DGN File

string MyDir = "Your Document Directory";
string sourceFilePath = MyDir + "Nikon_D90_Camera.dgn";

using (DgnImage cadImage = (DgnImage)Image.Load(sourceFilePath))
{
    // Your code here...
}

Step 2: Configure Rasterization Options

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.PageWidth = 600;
rasterizationOptions.PageHeight = 300;
rasterizationOptions.NoScaling = true;
rasterizationOptions.AutomaticLayoutsScaling = false;

Step 3: Create PDF Options

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

Step 4: Save as PDF

cadImage.Save(MyDir + "ExportDGNToPdf_out.pdf", pdfOptions);

Conclusion

Congratulations! You’ve successfully exported a DGN file to PDF using Aspose.CAD for .NET. This tutorial covered the essential steps, from loading the DGN file to configuring rasterization options and saving the output as a PDF.
