A 3D model of a plunging meso‐scale chevron fold affecting Mesozoic limestone has been generated, scaled and oriented applying a photogrammetrically based workflow. Bedding measurements allowed extracting the statistical direction of intersection between the bedding planes (the fold's β axis), allowing for the orthorectification of the 3D model and the construction of a photo‐realistic cross section. The methodology in this contribution constitutes an innovative tool, available to all, for the accurate quantitative analysis of geological structures.
