DWG files are the dominant format for architectural and engineering drawings. Because many recipients do not have CAD applications, sharing DWG directly can be difficult. Converting DWG to the universally accepted PDF format solves this problem. In this article we demonstrate how to perform DWG‑to‑PDF conversion programmatically with C#.
DWG to PDF Converter - C# API Installation
To convert DWG to PDF in C#, install the Conholdate.Total for .NET library, which provides a robust DWG‑to‑PDF API. Use the NuGet Package Manager or run the following command in the Package Manager Console:
PM> NuGet\Install-Package Conholdate.Total
Convert DWG to PDF in C#
The basic conversion workflow consists of three simple steps:
- Load the source DWG drawing with the Image class.
- Create a PdfOptions instance to define the output format.
- Call the Save() method to generate the PDF file.
The code sample below demonstrates these steps in a clear, concise manner:
Convert DWG to PDF using Custom Settings in C#
For greater control over the resulting PDF, you can configure additional properties in the PdfOptions and CadRasterizationOptions classes. This approach lets you adjust page size, resolution, vector rendering, and other advanced settings.
Follow these steps:
- Load the DWG file with the Image class.
- Instantiate CadRasterizationOptions to specify rasterization behavior.
- Create a PdfOptions object and assign the VectorRasterizationOptions property.
- Execute Save() to produce a PDF that reflects your custom configuration.
The sample code illustrates how to apply these custom settings:

FAQs
Can I integrate DWG to PDF conversion into a web application using C#?
Yes, the Conholdate.Total API works in ASP.NET, ASP.NET Core, and other C# web frameworks, allowing you to convert DWG files on the server side.
Is there a way to customize the output PDF settings during conversion?
Absolutely. You can modify properties such as page size, resolution, rotation, and vector rasterization options through the PdfOptions and CadRasterizationOptions classes.
Can I batch convert multiple DWG files to PDF in C#?
Yes. By looping through a collection of DWG file paths and applying the same conversion logic, you can automate batch processing of dozens or hundreds of drawings in a single run.
