Does somebody could give me the autore's name of this drawing?

Here's a thought that has occurred to me many times: "gee, I'd like to study x instrument in y museum or collection, I should check if there are CT scans of it" Much more often than not, there are not scans of the instrument in question. I realize that this is the case for a reason, namely that it's expensive to get access to the instrument, the equipment, and the few people with the specific knowledge required to take and render usable scans. I am sure that many of you have experienced the same thing. Perhaps if enough people come together, though, we could do something about it. Provided we know what we want scanned, who we want to scan it, and how much it would all cost, we could go about getting the money together to do it, and crowdfunding seems the obvious 21st century way to do it. Please share your thoughts.

I want to know which CAD tools you use. How steep is the learning curve? Did you take a course? Or do you have assistance from a professional? What's the cost? I learned Euclidean geometry by use of compass and ruler. It would be nice to be able to illustrate my ideas in this forum and elsewhere. Often a drawing says more than words. So, please help me get my ideas across. I am thinking of the illustrations by Kevin Kelly, Addie, David Beard, F. Denis etc. How do you do it?

As I was staring recently at tables of measurements of some rather ‘Nice’ Cremonese instruments, it struck me that the numbers that make up a violin are (or could in theory be) prime. For example: Body length: 353 Upper bout width: 167 Center bout width: 109 Lower bout width: 211 Distance between upper eyes of FFs: 41 Distance of lower lobe of FFs from edge: 13 Mensure: 193 (if you’re Del Gesu), or 197 (if you’re making the ‘Soil’) Width of scroll: 41 Narrowest point of scroll: 11 Length of scroll: 103 Neck length: 13 (cm) Coincidence? I think not! Is it a coincidence that the moon is made of cheese? Is it a coincidence that the Sun is the center of the galaxy, nay, universe?! I think not!
