The Convex Hull tool creates a polygon essentially by wrapping a rubber band around a collection of paths. You have two construction options
- Consider ALL Paths
- Points Only
The Points Only option will only use Points for the wrapping and ignore all other paths. The Consider ALL Paths option will use all the Snapping Points on every path within the selection rectangle. This can be very useful for creating hybrid curved/straight shapes. For instance, create a circle with a large number of Snapping Points (say, for instance, 360) and wrap it with a triangle. Here’s a simple example:
And here’s an example using hundreds of points:
