A fixture is provided for locating a workpiece in space including a blade having a longitudinal axis, a bottom edge, a top edge, and a plurality of through-bores. At least two of the through-bores are positioned on the blade to define a predetermined location relative to the top and bottom edges, and together with a riser, allow for the precise positioning of a locating pin, or other datum point locator, that may be attached to the blade. The blade also includes a mounting arm that is eccentrically located on a top edge. The mounting arm has a plurality of through-bores, where at least two of the through-bores define a predetermined location relative to the top edge. A locating pin, or other datum point locator is attached to the mounting arm. The fixture is particularly adapted for use in a modular system of fixtures, in that by stocking a variety of blades, each with a different set of through-bore locations, a different positioning fixture may be formed, as needed, without the need for custom manufacturing of blades. Also, due to the eccentric location of the mounting arm on the blade, a simple rotation of the blade about its longitudinal axis allows for a doubling of the locations at which a locating pin, or other datum point locator may be positioned in space. These features allow for kits of blades to provided from which a variety of fixtures may be created.
