Transform - Convex Hull

Given a set of points, this operator creates an area about the points using the positions of the extremal points as the bounding coordinates for the area. This is easiest to visualize if we imagine the points to be vertical pegs set on a board and a rubber band is placed around the collection of points to define the shape of the area.

Running the convex hull transform on the points at left results in the area seen at right. The area line created by this operator will be selected after it is created.

 

Tech Tip

 

Many transforms automatically run a Normalize Topology transform before running to eliminate common errors that may affect correct operation. The Convex Hull transform operator does not normalize target objects before running.
