Back to school
I have been using Autodesk Fusion 360 for designing parts for 3D printing for about a year. It's a really complex program but I thought I had taught myself how to use it OK with the help of Youtube videos. However, I decided that I needed some proper training and enrolled on an online course.
Today was day one and it was amazingly good and I learnt an enormous amount (including unlearning a lot of bad habits)
This was one of the test pieces we worked on. Don't ask me what it is - I am sure an engineer out there will enlighten me. I was amazed how much simpler the whole process was when done properly. I just hope I can remember it all. The course lasts 3 days so I'm expecting to be an expert at the end. It's a bit nerdy but good fun.
