Abstract
An alignment aid that includes a surface that defines a plane. First, second, and third references are aligned along a first axis of the surface, wherein each reference has a length along the first axis and a width along a second axis orthogonal to the first axis. A distance is between adjacent references along the first axis. Each reference includes a first alignment feature adjacent to a second alignment feature. Each first alignment feature has a first alignment feature elevation orthogonal to the first and second axes. Each second alignment feature has a second alignment feature elevation orthogonal to the first and second axes. For each reference, the first alignment feature elevation is higher than the second alignment feature elevation.
