As an engineering student, we design a lot of things, specifically my course in aviation-related. But instead of being traditional, like drawing on a large tech-paper, we use(learning) digital products like AutoCad.
I've used a lot of things like Adobe Photoshop, Illustrator, Paint Tool Sai, and so on...but of course, it was my first time using AutoCad, so I decided to fiddle around a bit. I was gonna make an aircraft, or an engine, or something, but...
I made them a few weeks back. These were both made using a mouse(the reason why some are not proportionate. I haven't tried using my tablet for it yet), it took me hours, and damn...my hand hurt during those times(and decided not to finish Yukari). Atleast I learned some of the tools though. Then screenied to Paint('cause it's faster that way...)
Anyways, I'm not going to go through that ordeal again. I'm thinking of becoming serious about using this program now, making 3D planes and stuff...yea, for "college work", that's it. :V
Note: Don't use AutoCad if you're just gonna draw something...'cause it's not just for drawing.
