Describe the tolerances required for use with undimensioned prints.

What will be an ideal response?


The features of the objects on an undimensioned drawing should be drawn with actual size and location tolerances of ±.010 in. (0.25 mm). The contour definitions on drawings, such as templates are provided to true profile. The tolerance of each grid line cell is ±.005 in. (0.13 mm) and the total grid tolerance is ±.010 in. (0.25 mm). The tolerance for the location of dimensional accuracy points is ±.010 in. (0.25 mm). The tolerance for the location of registration marks is ±.005 in. (0.13 mm).
