The present study shows the process followed in making the three-dimensional model andgeometric documentation of a historical invention of the renowned Spanish engineer Agustin deBetancourt y Molina, which forms part of his rich legacy. Specifically, this was a wind machine fordraining marshy ground, designed in 1789. The present research relies on the computer-aideddesign (CAD) techniques using Autodesk Inventor Professional software, based on the scantinformation provided by the only two drawings of the machine, making it necessary to proposea number of dimensional and geometric hypotheses as well as a series of movement restrictions(degrees of freedom), to arrive at a consistent design. The results offer a functional design for thishistoric invention
