I'm an intern at an engineering company and my TLDR is basically this:

I'm trying to save the company money by taking away projects from our overworked machinist and 3D printing the parts instead. The issue I have is when I'm gone, there going to have to pay a full time engineer or CAD technician to model these parts which just won't happen. I was wondering if I could make a sort of automated system that will cut the time down to model to be hardly an inconvenience. 

The issue is I know nothing about C# (really only have arduino and matlab experience), but it seems like the software to do the trick. All I want it to do is carry out several features already is solidworks. I've attached a short slideshow walking through the best case scenario of what I want it to do.

Should C# do the trick? Is it worth learning completely from scratch? Can I learn the language and do what I want it to in a month and a half? What in my plan is unrealistic or impossible?

Any insight would help a ton!
