I first started by creating a box and ran into a whole host of issues. Could not get box to in right perspecive and dimensions are weird took a very very long time to get this.
Then after showing my friend how I was trying to do everything in one sketch they brutally corrected me and learned components ... kind of
Then I put the two together and then had to learn about joining pieces and that was a nightmare, so I am happy with what I got to.
