Convert DGN to PDF in Aspose.CAD for .NET

Introduction

Navigating the world of CAD files can be challenging, but with Aspose.CAD for .NET, developers can easily manipulate and convert various CAD formats. One common need is converting DGN files to PDFs, which we’ll explore step by step in this tutorial.

Prerequisites

To follow along, ensure you have the following:

• Basic proficiency in C# and the .NET framework.
• Aspose.CAD for .NET library installed. You can download it here.
• A sample DGN file (e.g., Nikon_D90_Camera.dgn).

Step 1: Import Required Namespaces

Start by importing the relevant namespaces in your C# project:

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

Step 2: Load the DGN File

Specify the directory for your DGN file and load it using the following code:

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

using (DgnImage cadImage = (DgnImage)Image.Load(sourceFilePath))
{
    // Additional processing will go here...
}

Step 3: Configure Rasterization Options

Next, set up the rasterization options to define how your DGN will be rendered in the PDF:

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions
{
    PageWidth = 600, // Adjust the width as needed
    PageHeight = 300, // Adjust the height as needed
    NoScaling = true,
    AutomaticLayoutsScaling = false
};

Step 4: Create PDF Options

Define the PDF options, integrating the rasterization settings configured earlier:

PdfOptions pdfOptions = new PdfOptions
{
    VectorRasterizationOptions = rasterizationOptions
};

Step 5: Save the DGN as a PDF

Finally, save the DGN file as a PDF using the options you’ve configured:

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

Conclusion

Congratulations! You’ve successfully converted a DGN file into a PDF using Aspose.CAD for .NET. This straightforward tutorial guided you through loading the DGN file, setting rasterization options, and saving the output as a PDF.
