👉 In mathematics, an undervaulting surface is a surface that has been flattened or reduced in size to its original shape. This can be done by using tools such as a plane and compass, which are used to draw lines through the surface and measure distances between them. For example, if you have a sphere of radius 1 centered at the origin (0, 0, 0), you could use a ruler and compass to mark points that are a distance away from the center of the
