Great tutorials, man! I'm working through them right now and it helps a lot! Have a question: Is there a way to direct loft operation rotation? If you want to loft two edges at 90 degrees to each other, is there a way to tell the program should it loft clock-wise or counter clock-wise? Apart from rotating the second part 180 degrees.

0:56 How did you make the loft on the other side have a different direction? I made them symmetrical on the left and right, and there will be interspersed when they are put together.

Also, do you know why object snapping does not work? I can't seem to snap anything to edges/faces when I grab or any other operation.

0:17 That's a three-point rectangle you made, holding mouse over the button? It's definitely a better way of making it here since the points snap on the circle tangents, making it flush on opposite site.

How do you make an exact rectangle of circle size? What is the short key for snapping?

Another thing i noticed: if the sheets won't join, delete the loft, spin one sheet 180° (R+Z+1+8+0+Enter), then loft the edges again. Also, my sheets won't join, so i copied the thickness value from one sheet and pasted it in another.
