Samples and prototypes handmade in the workshop using the common bench tools.
Digital palette tools
VS
Analogic palette tools.
There's a project phase in which you must leave the software and its palette - the "digital&virtual tools" - and get off in the workshop and use the bench tools - the "analog&real palette.
In this case it comes to identifying the best of 3 different belt tensioner lever solutions.
At PC all the solutions are the same. Realizing the 3 prototypes has been able to determine the best.
