I have a cylinder that has rectangular box regions to mark the leakage problem. The location of the 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 to convert this cylinder to plane surface so that I could locate the location of rectangular boxes in 2D plane? Here I have three rectangles on the surface.
