At its heart, VDF is an SDK component designed to make the creation, management, and printing of 2D and 3D drawings as intuitive as possible. It is a fully object-oriented (OOP) library, ready for .NET 2 and beyond, and includes a full-featured ActiveX component for broader compatibility. The core of the framework is its powerful, XML-based format known as (and its compressed sibling, VDCL). This format is a key differentiator: it allows for the creation of custom objects that remain independent of the component's version, ensuring long-term project stability and data integrity. All drawing-related operations in VDF are managed through the vdDocument object, which acts as the central hub for file I/O, external references (Xrefs), undo/redo history, event handling, and collections of layouts, layers, blocks, and other drawing elements.
Comprehensive event model allows developers to respond to user actions (e.g., clicking an entity, changing a view). Advantages of Using VectorDraw Developer Framework At its heart, VDF is an SDK component
