I know this is very old and the author likely knows the answer already but it also brings up an issue with "Drawing" for me.
The two standards in Fusion: ISO and ASME set two primary differences - sheet size and angle projection. Traditionally, the US has used third angle projection and sheet sizes like letter and the UK and Europe has used first angle projection and the A series of sheet sizes*. Unfortunately Fusion 360 makes that traditional assumption a fixed one.
The issue for me is that I did third angle projection in university as did everyone I know (I'm Irish not British). I would hazard that many UK engineers also do 3rd angle as a default although there are likely plenty who still do 1st.
You can see the issue - Fusion 360 insists on coupling the sheet size and the projection together. So while I would use A4 and third angle as a default position, you cannot do that in Fusion 360. It's either A4+first or Letter+third. Be nice if that would change 🙂
* PS: For anyone who doesn't know, the A series were designed by engineering nerds and have length to width ratios of 1 to 1/sqrt(2). Thus you can reduce A4 to A5 without aspect ratio changes, put two A5 portraits on one A4 landscape etc. Drives me completely nuts to try and use Letter on a photocopier!
