Prop vectors and angles question

[Nox Deleo]

In an attempt to understand prop vectors and angles (and how local and world relate), I've been making a little client side draw function that extends X, Y and Z axes from a PHX prop.

function ENT:drawAxes()
  render.SetMaterial(Material("cable/cable2"))
  -- X
  local beamStart = self:LocalToWorld(Vector(0, 0, 0))
  local beamEnd = self:LocalToWorld(self:GetLocalAngles():Up() * 10)
  render.DrawBeam(beamStart, beamEnd, 2, 1, 1, Color(255, 0, 0, 255))
  -- Y
  local beamStart = self:LocalToWorld(Vector(0, 0, 0))
  local beamEnd = self:LocalToWorld(self:GetLocalAngles():Right() * 10)
  render.DrawBeam(beamStart, beamEnd, 2, 1, 1, Color(0, 255, 0, 255))
  -- Z
  local beamStart = self:LocalToWorld(Vector(0, 0, 0))
  local beamEnd = self:LocalToWorld(self:GetLocalAngles():Up() * 10)
  render.DrawBeam(beamStart, beamEnd, 2, 1, 1, Color(0, 0, 255, 255))
end

What I'm seeing is that when I rotate the prop, rather than rotating in the direction of the prop rotation, the axes I drew are rotating around different ways.

My understanding is:
- I get the local vector representing the center of the prop.
- I convert this local vector to a world vector, so I know where the center of the prop is in the world, and start my beams from there.
- I get normalized forward (X), right (y) and up (z) local vectors representing the axes of the prop.
- I multiply these by 10, so they end 10 units away from the prop center on the given axis.
- I convert these end points to world vectors so I know where they are in relation to the world.
- I draw the visual representation of the axes using the world coordinates I've just calculated.

So, what have I gotten wrong? My vector/angle understanding, my code, or both? Thanks in advance.

On a side note, I couldn't find anywhere how to syntax highlight my code on here.

Figured this one out myself when I took a fresh look, and realised I'd gotten myself confused. I've more or less gotten a grip of the whole world/local stuff now.

function ENT:drawAxes()
local beamStart = self:GetPos()
render.SetMaterial(Material("cable/cable2"))
-- X
local beamEnd = self:LocalToWorld(self:WorldToLocalAngles(self:GetAngles()):Forward() * 10)
render.DrawBeam(beamStart, beamEnd, 2, 1, 1, Color(255, 0, 0, 255))
-- Y
local beamEnd = self:LocalToWorld(self:WorldToLocalAngles(self:GetAngles()):Right() * 10)
render.DrawBeam(beamStart, beamEnd, 2, 1, 1, Color(0, 255, 0, 255))
-- Z
local beamEnd = self:LocalToWorld(self:WorldToLocalAngles(self:GetAngles()):Up() * 10)
render.DrawBeam(beamStart, beamEnd, 2, 1, 1, Color(0, 0, 255, 255))
end
