Cam3D2D Trouble

[Monkey4TL]

I am trying to use cam3D2D in order to make a display for a custom printer. The display works well until the roll/yaw/pitch is changed:

If possible I would like to know how to prevent the yaw/pitch/roll change from effecting the distance from the face of the prop.

Here is my code:

function ENT:Draw()

	self:DrawModel()
	local pos = self:GetPos()
	local ang = self:GetAngles()
	
	pos:Add(Vector(0,0,15))
	ang:RotateAroundAxis(ang:Up(), 0)
	ang:RotateAroundAxis(ang:Right(), 90)
	
	cam.Start3D2D(pos + ang:Up() * -13.7, ang, 0.11)
		draw.RoundedBox(0, -125, -125, 250, 250,Color(0, 0, 0, 240))
	cam.End3D2D()

end

Any help is appreciated, thanks.

Fixed it!

Turns out the problem was that I was adding a fixed amount while adding a proportional amount to the position of the prop

Problem:

pos:Add(Vector(0,0,15))
