Introduction VectorDraw Developer Framework (VDDF), historically known as VectorDraw Standard, is a software development kit (SDK) designed to enable developers to embed CAD-like drawing, visualization, and editing capabilities into their Windows desktop, web, and mobile applications. It provides a programmable drawing surface, object model, file I/O, rendering pipeline, and user interaction primitives that mirror many features of traditional CAD systems while emphasizing integration flexibility and extensibility for custom apps.

A land surveying firm uses VDF CAD inside a custom C# application to import total station data (CSV) and automatically generate a 2D plat map. The framework handles scale bars, coordinate transformations (World to Paper), and exports the final drawing as a DWG for city officials.

Download the 30-day trial. Unlike many competitors who offer limited "watermarked" demos, VectorDraw provides a fully functional evaluation. Take a complex DWG from your production line, load it into the C# sample project, and test the save-roundtrip. If it survives your worst-case file without crashing, you have found your engine.

: The framework is primarily written in managed .NET C# code, offering deep integration with Visual Studio. VectorDraw Backward Compatibility

We are excited to announce that VectorDraw Standard has been rebranded as VectorDraw Developer Framework CAD, reflecting the framework's enhanced capabilities and expanded scope. As a leading provider of CAD development tools, we are committed to empowering developers, ISVs, and VARs to create innovative CAD solutions that meet the evolving needs of the industry.
