Well it was possible. Katy spent the first morning going through the basic techniques we'd need to realise our design, then left us to it.
By the end of that day, I had one side of one design done and the next day I'd completed two whole concepts (4 sides total).
I admit I got a bit confused with recreating my hallmark. Because it would be used to print, the lettering had to be reversed. However my initials are vertically symmetrical, so spinning 180deg corrects this reversal (leaving me wondering if I'd done it right).
On the Thursday, Dauvit did a couple of checks on each of our designs and made a machine readable file to send off for printing.
I don't have time to recreate the whole process and write out the instructions long hand, so I have typed up the scrappy notes I made on the day.

After spending the Monday & Tuesday doing this CAD model, I spent Wednesday modelling my final kinetic piece for my Fine Jewellery optional module. That was a complicated design and I'm now quite confident I have a good understanding of the Rhino software (using computers just comes naturally to me).
