ABSTRACT:
A system is disclosed for materializing in space a point whose coordinates in a system of reference axes are known, comprising:
an optical aiming apparatus, occupying a pre-determined position with respect to said system of axes and making it possible to determine, in said system of axes, the coordinates of any point aimed at, and
a tooling assembly comprising a stand, one part at least of which is movable with respect to said system of axes and a hemispherical ball joint mounted in a spherical concave seat fixed to said movable part of the stand, the center of said ball joint being marked so as to be visible by said aiming apparatus.
