Using Custom Grips to Enhance User Interaction with AutoCAD Entities

Description

AutoCAD uses grips showed with a selected object not only to provide visual hints of the object—such as start/end/center points, or mid/tangent points or vertices—but also, more importantly, to provide shortcuts to various operations against the object, such as stretch, move, rotation, and scale. Other AutoCAD-based applications (Civil 3D software, AutoCAD Architecture software, AutoCAD MEP software, and so on) use custom grips with architecture, engineering, and construction (AEC) entities extensively. Fortunately, with .NET API, we can add custom grips to an AutoCAD object for our own specialized operation against the selected object. This session will show you a few practical examples of using custom grips.
