mathematical arc for openSCAD

This module works in the trigonometric circle. As a reminder and without wishing to offend you, the trigonometric circle has its 0 which corresponds to the x-axis and its direction of rotation is counterclockwise. The start value should ever been lower than end value. In v2, I added a check up of the start and end values to avoid some issues with the computations. I have improved the processing of the angles and reduced the number of polygons to draw to open the circle. You can use it as a module in your project or include it in your library. How I Designed This The received angles are checked to convert them if necessary in accordance with the operation of the trigonometric circle. The opening angle is divided into a minimum of angles less than 45 ° The height of each triangle is calculated to be larger than the outer circle A loop draws the triangles from the start value to the end value in the difference scope The triangles overlap by 2 ° which is the lower limit of treatment.
