The add-on includes a CVH command specifically for constructing convex hulls from a set of points, helping users manage GIS and CAD data more effectively. Core Principles of Convex Hulls convex hull autocad
The most efficient way to generate a convex hull in standard AutoCAD is using a scripted command. Since the mathematics behind calculating a hull (typically using the Graham Scan or Gift Wrapping algorithms) is complex for a human to do manually, a script handles it instantly. (Graham scan algorithm – save as
