I have a cylinder that has rectangular box regions to mark leakage problems. The location of a rectangular box is determined by its initial position in the longitudinal axis and its initial position in the circumferential axis in degree. The length and width (in degrees, from 0° to 360°) of the boxes are also available.
How can I convert this cylinder to a plane surface so that I can find the location of the rectangular boxes in the 2D plane?
Here I have three rectangles on the surface.
