Describe the function of dimensional accuracy points, including how dimensional accuracy points are displayed and dimensioned on a print.

Question

What will be an ideal response?

Answer 1

Dimensional accuracy points are a set of points located in a rectangular pattern surrounding the object and within the drawing border to establish a means of dimensioning horizontally, vertically, or diagonally across a drawing to validate dimensional accuracy. A minimum of four dimensional accuracy points are used on a drawing. Six dimensional accuracy points are used when the limits of the drawing exceeds the ability of the verification process. The horizontal and vertical location of the dimensional accuracy points are controlled directly or with a reference. When controlled directly, extend a line capped with arrowheads horizontally and vertically from one of the points. A dimension is placed on each line giving the dimensions to the adjacent dimensional accuracy points on the drawing. When six points are used, the center point has three dimension line segments with dimension values to the adjacent points.
