Algorithm (Workflow)

This algorithm generates a Closed Polygon List (CPL) for the Anycubic Predator Z-Level testing solid. The function does not take any input parameters and outputs a CPL representing the contour of the testing solid.

Parameters and Variables

Do: An array [360, 260, 140, 20] representing diameters of circles.
Ro: An array calculated as half of each element in Do, representing radii of circles.
B: A constant value 5, used as a border or offset.
H: A constant value 1.5, not used in the algorithm.
CPL: An empty array initialized to store the final Closed Polygon List.

Algorithm Steps

Initialize the diameters array Do and calculate the radii Ro by dividing each element of Do by 2.
Initialize an empty array CPL to store the polygon data.
Iterate over each radius in Ro:

For each radius, append the circle polygon data generated by PLcircle(Ro(i)) to CPL.
Append a NaN separator to CPL.
Append the inner circle polygon data generated by PLcircle(Ro(i)-B) to CPL.
Append another NaN separator to CPL.

Remove the last NaN separator from CPL.
Union the current CPL with a square polygon generated by PLsquare(max(Do)-B/2, B).
Union the current CPL with another square polygon generated by PLsquare(B, max(Do)-B/2).
Union the current CPL with a circle polygon generated by PLcircle(min(Ro)).
If no output argument is specified, plot the CPL using SGfigure and CPLplot functions.
