Hi, I’m Karolina!
I get it!! I’d probably have some doubts if I saw this online too.
To be fair, I definitely did not get good at Fusion in a day (I’m still not very good at Fusion). The Day 1 CAD was all flat shapes -- all I had to do was use the line, curve, and pattern/mirror tools and then extrude those shapes to my body plate / arm thickness. Same with the screw holes -- I didn’t know there was a hole tool and was just drawing circles, patterning them, and extruding them backwards. It still took me forever, I started super early in the morning and worked on it until ~2pm, knowing it would probably take a MechE major 30 mins to do the same thing.
I also do have mentors in the form of eng majors who can give me verbal feedback / advice / show me which tools to use / get me unstuck. To me, it was very important that I was the only one actually doing the CAD so I could learn, but I definitely have had super amazing mentorship along the way to teach me and point me in the right direction. The motors and props are just 3rd-party components that I imported (still took me ages to figure out how to constrain them right). I went to the machine shop after and that took forever too, especially figuring out how I’m supposed to arrange the plates for printing in Fusion (but I had people to help me out there, they were not going to let me use a CNC mill alone with no exp lol)
I made the GPS / receiver mount way later in the process because I was so intimidated by the CAD for it (literally taped my GPS and my receiver to the drone for the first flight instead), and it took me days (also such a simple component, but the stuff that’s not just an extruded 2D shape is way harder for me).
I’m definitely not superhuman and it’s probably going to be years before I feel truly confident in Fusion :))
