Supported DGN Elements in Aspose.CAD for .NET

Introduction

Are you a .NET developer looking to work with DGN files seamlessly? Aspose.CAD for .NET provides a robust solution to handle DGN files efficiently. In this tutorial, we will delve into the supported DGN elements, guiding you through the process of working with Aspose.CAD for .NET.

Prerequisites

Before we begin, make sure you have the following:

• Basic knowledge of .NET programming.
• Visual Studio installed on your machine.
• Aspose.CAD for .NET library, which you can download here.

Import Namespaces

To kickstart your project, import the necessary namespaces into your .NET application. This step ensures that you have access to the functionalities provided by Aspose.CAD for .NET.

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

Step 1: Load the DGN File

Begin by loading an existing DGN file as a CadImage in your .NET application.

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

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

Step 2: Iterate Through DGN Elements

Iterate through the DGN elements using a foreach loop. Aspose.CAD for .NET provides a variety of DGN element types that you can work with.

foreach (DgnDrawingElementBase element in dgnImage.Elements)
{
    // Your code here
}

Step 3: Handle Previously Supported Entities

Handle the previously supported 2D entities, which are now also supported for 3D.

switch (element.Metadata.Type)
{
    case DgnElementType.Line:
    case DgnElementType.Ellipse:
    case DgnElementType.Curve:
    // Additional cases
        {
            // Your code here
            break;
        }
}

Step 4: Handle Supported 3D Entities

Handle the supported 3D entities provided by Aspose.CAD for .NET.

switch (element.Metadata.Type)
{
    case DgnElementType.SolidHeader3D:
    case DgnElementType.Cone:
    case DgnElementType.CellHeader:
        {
            // Your code here
            break;
        }
}

Step 5: Export and Save

Finally, export the modified DGN file to a raster image and save it to the specified directory.

Console.WriteLine("\nThe DGN file exported successfully to raster image.\nFile saved at " + MyDir);

Conclusion

In this tutorial, we explored the capabilities of Aspose.CAD for .NET in handling and manipulating DGN files. By following the step-by-step guide, you can efficiently work with supported DGN elements, whether they are 2D or 3D entities. Aspose.CAD for .NET empowers you to seamlessly integrate DGN file processing into your .NET applications.
