The present paper deals with a convenient, manual method for making oblique graphical reconstructions from serial sections. The method is based on a projection on the plane of drawing of a three‐dimensional coordinate system, which is submitted to two successive and predetermined spatial rotations. Restriction to two rotations simplifies the mathematical approach to a coordinate transformation from a three‐dimensional into a two‐dimensional system. The resulting formulae, which are quite easily applied, lead to a quick visualization procedure.
