By defining new custom tools, you extend the built-in tools available to you in Sketchpad. Any custom tool you define can be used an unlimited number of times in an unlimited number of sketches. A more advanced custom tool might create a fractal, or a tangent to an arbitrary point on a function plot, or a complex tessellation. For example, you can make a custom tool that constructs the perpendicular bisector of a given segment, or one that constructs the circumcircle of a given triangle, or one that constructs a square given two adjacent vertices. In just the way that Sketchpad’s Compass tool constructs a circle given its center and radius point, custom tools that you create can construct figures of arbitrary complexity. When you press and hold the Custom tool icon, the Custom tools menu appears.Ĭustom tools are tools that you create yourself or that other Sketchpad users create for you. The Custom tool icon shows commands that allow you to define and use custom tools.
