In 2012 I started with Blender. I wanted to make truck trailer for first project. Rotating on my own without using axis and was trying to rotate as close possible to 90. Didn't know I could just type R X 90. I'm making fast render scenes, I don't like to wait long for render. Render tooks over 15s per frame? Go away then.
I'm about 2 years in blender but not on serious projects, just messing around.
