using System;
using GroupDocs.Conversion;

// Initialize the conversion handler
class Program
{
    static void Main()
    {
        var converter = new Converter("path/to/your/file.dgn");
        Console.WriteLine("Setup complete. Ready to convert!");
    }
}

Implementation Guide

Load and Convert DGN File to TXT

Overview

This feature allows you to load a DGN file and convert it into TXT using GroupDocs.Conversion for .NET, useful for extracting text data from architectural or CAD files.

Step 1: Define the Output Directory Path

Specify where your converted files will be saved:

string outputFolder = Path.Combine("YOUR_OUTPUT_DIRECTORY", "ConvertedFiles");
Directory.CreateDirectory(outputFolder); // Ensure directory exists

Why: Specifying an output path organizes and simplifies access to your files.

Step 2: Set Up Conversion Options

Create conversion options for TXT:

var convertOptions = new TextConvertOptions();

What It Does: This object holds settings required for the conversion, allowing customization of how files are transformed.

Step 3: Perform the Conversion

Execute the conversion with specified parameters:

converter.Convert(() => File.Create(Path.Combine(outputFolder, "output.txt")), convertOptions);

Why: The lambda expression enables efficient file creation during the conversion process.

Troubleshooting Tips

  • File Not Found Error: Ensure your DGN file path is correct and accessible.
  • Permission Issues: Check if your application has write permissions for the output directory.
  • Conversion Errors: Validate that all dependencies are correctly installed and referenced in your project.

Practical Applications

This conversion capability can be integrated into:

  1. Data Extraction: Extract text data from DGN files for analysis or reporting purposes.
  2. Interoperability: Facilitate the integration of architectural designs with systems requiring TXT input.
  3. Automation Workflows: Incorporate this step into automated document processing pipelines.

Performance Considerations

When working on file conversions, consider:

  • Optimize Resource Usage: Monitor memory usage during large batch conversions and optimize where necessary.
  • Efficient Memory Management: Dispose of objects no longer needed to free up resources quickly.
  • Batch Processing: Handle multiple files simultaneously for improved throughput if required by your application.

Conclusion

Congratulations! You’ve mastered converting DGN files to TXT using GroupDocs.Conversion .NET. Integrating this functionality into your projects enhances data handling and interoperability across platforms.
