Rotate a prop on the bottom left?

Yo,

I’m trying to make it so when someone presses E on this prop it will rotate 90 degrees around the bottom left of the prop.

It rotates when i press E on it however it’s doing it around the center of the prop



-- Ent use with cooldown stuff

	local Ang = self:GetAngles()
	Ang:RotateAroundAxis(Ang:Up(), -90)
	self:SetAngles(Ang)



To do this, you need to:
translate so the arbitrary point is the origin
rotate
translate back
