Web Hole / Feature Pattern Plot ;

An established “true” central plane is established from the datum and for the symmetry to be in tolerance, the median distance between every point on the two surface features needs to fall near that central plane. In the mss feature control frame, the bottom framework refines both the location and orientation of the top frame. The holes in the pattern have a feature size tolerance of ±0.1 mm and a position tolerance of 0.5 mm at mmc with respect to datum reference frame abc. Web using one of the holes as a datum, has the advantage that it translates more directly into an inspection procedure.
