WIPO Patent Application WO/2020/196030

A1

This gauge (10g) has a reference body (11g) and a gauge body (13g). The reference body (11g) has a plurality of reference parts (20) located at mutually different positions and enable defining of a coordinate system. The gauge body (13g) is connected to the reference body (11g). The gauge body (13g) includes a plurality of planar sections or a plurality of curved sections (C1g, C2g, C3g, C4g) having mutually different curvature radii, wherein each of the curved sections or planar sections has a free-form surface (Fbg) that is contiguously connected to another one of the plurality of curved sections or planar sections.
