Inserting Values and Functions from the Sketch

While you’re using the Calculator to define a calculation or a function, you can click existing values or functions in the sketch to insert these objects into your new expression. For instance, if you have a sketch in which you’ve already measured the length of segment AB, you can insert this length into the Calculator’s expression by clicking on the existing measurement in the sketch. Similarly, if you have a sketch in which you’ve defined a function f (x ) = ax² + bx + c, you can use this function in other calculations and functions by clicking on it in the sketch.

If a value or function you want to insert is hidden behind the Calculator itself, drag the Calculator to the side so you can click on the object you want to insert.
