Abstract: A shape analysis method for analyzing shape data acquired by measuring a contour shape of a workpiece to be measured, includes: deciding a geometric element used in shape analysis; deciding one data point to be included in an evaluation range; applying the geometric element to an interval including the one data point; searching the widest interval for satisfying a threshold condition of a preset shape tolerance while changing a width of the interval; pinpointing two boundary points between which the interval found by the search is sandwiched; obtaining two edge points at which the two boundary points are respectively shifted by preset shift amounts; setting a range sandwiched between the edge points in the evaluation range; and targeting the shape data within the evaluation range for calculation of geometric properties.
