Bentley uses modern CAD software, metrology equipment to recreate a small number of 1929 racecars.

British luxury carmaker Bentley plans to produce 12 Bentley Blower vehicles, exact replicas of a famed 1929 racecar. Good luck finding the CAD files on those.
All 12 cars are already sold to collectors around the world, and the first stages of build for Bentley's own engineering prototype – Car Zero – will begin as soon as non-essential employees return to work.
A key step was creating a complete CAD model in Dassault Systèmes’ Catia software by inputting nearly century-old blueprint data and scanning components with Faro metrology scan arms.
At Bentley, the Blower’s finished CAD model contains 630 components and 70 assemblies and is bigger than 2GB. Engineers spent more than 1,200 hours to complete the model from the scan data and hand measurements.
The detailed 3D model allows the 12 Blower buyers to spec colors and materials for their cars, sticking to the options available in 1929.
