CAD Support

Bring accurate, reliable and fast support for CAD and BIM formats to any application or workflow with a CAD SDK proven to handle the large and complex drawings used in today’s architecture, engineering, and construction workflows.

High-Level Capabilities

What could CAD look like in your application?

No CAD Licenses

Support CAD and BIM formats, including Autodesk AutoCAD® DWG™, DXF™, RVT™, DWF™, and Bentley MicroStation® DGN™, without you or your users needing any CAD software or CAD licenses.

Web, Server, Desktop

Add CAD functionality to any platform with a unified API across web, Windows, Mac, or Linux. Use a single codebase with Xamarin, React Native, Flutter, or other frameworks.

Fully Customizable UI/UX

Increase adoption and productivity by simplifying the open source UI. Match your desired look and feel. Hide unnecessary features — or add custom annotations that trigger workflows.
