Many people do not understand how to rotate a brick through a script. To rotate a brick, we use CFrame.
Normally CFrame just positions a brick, but by adding a few extra words, it can also rotate bricks.
We do this by adding *CFrame.Angles(0,0,0) after we CFrame a brick to its position.
(Replace 0,0,0 with the rotation angle you want)
p = Instance.new("Part")
p.CFrame = CFrame.new(0, 10, 0)*CFrame.Angles(0,0,0)
The first part Positions, the second part rotates. You do not need to put *CFrame.Angles to use CFrame, CFrame can also be used just for positioning bricks. I hope you learned something from my tutorial.

what does Vector3.new do then?

It can be a size or position. Pretty much anything that can be classified as 3D

So pretty much ROBLOX added an extra command? I think there's more to that.

Cframe puts an object somewhere no matter what else is there. Vector3, when used to position something, places as close to the place you specify, raising the Y value until it can fit.

he forgot to tell us that the angles were in radians. :P
to convert degrees to radians you can do math.rad(degrees) or (math.pi*2)/(360/degrees)

Ah, math. Lovely

yup.

to convert radians to degrees you can do math.deg(radians) or 360/((math.pi*2)/radians)

he should really space out his tutorials in paragraphs, that way people will understand it better!
