MI.NET - Janvi Saddi - CAD Automation with C# and .NET

Agenda

• 5:30 - 6:30pm Networking
• 6:30 - 7:30pm Presentation
• 7:30 - 7:45pm Closing

Abstract
Many engineering teams rely on CAD applications every day, yet repetitive drawing updates, object validation, block modifications, and quality checks are still performed manually.

This session demonstrates how C#, .NET, Visual Studio, and CAD application APIs can be used to build practical custom automation tools. Attendees will learn how to create a .NET class library, connect it to a CAD environment, define custom commands, and safely read or modify drawing objects such as blocks, attributes, and layers.

The session will also cover transaction handling, input validation, exception handling, debugging, DLL deployment, and user-friendly error reporting. Using a practical engineering workflow as a case study, the talk will show how a repetitive manual process can be converted into a maintainable internal tool that improves accuracy, consistency, and productivity.

The concepts can also be applied to other desktop applications that expose .NET APIs. No previous CAD development experience is required.
