Think of it like stretching a rubber band around the outermost points.
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
As he worked in AutoCAD, John recalled a concept from his college days: the convex hull. A convex hull is the smallest convex polygon that encloses a set of points in a plane. In essence, it's the outermost boundary that completely contains all the points. Think of it like stretching a rubber band
You can find many free LISP routines online (commonly named ConvexHull.lsp or TIN.lsp ). Alternatively, copy the code snippet at the bottom of this article into a text file and save it as ConvexHull.lsp . A convex hull is the smallest convex polygon
(Full implementation requires sorting and cross-product checks – search “AutoCAD convex hull LISP” for ready-to-use scripts.)
For users who need a robust, UI-driven tool, the Spatial Manager plugin offers a dedicated command: Run the command. Select your objects (manually or by layer).
Every interior angle is less than 180 degrees, meaning all vertices point outward.
