Rotate box collision

[rute]

I used this to create box collision for my entity:

shared.lua
[lua]
function ENT:Initialize()
self:SetModel("models/props_c17/chair02a.mdl")

local min = Vector(0,0,0)
local max = Vector(50,100,50)

self:PhysicsInitBox(min,max)
self:SetCollisionBounds(min,max)
self:PhysWake()
end
[/lua]
But the collision does not rotate with the entity no matter how much I rotate it.
It does collide with physics, but stops players and traces in thin air.

How to make simple box collision that does rotate with entity?

If I remember correctly, you have to [url=http://wiki.garrysmod.com/page/Entity/EnableCustomCollisions]enable custom collisions[/url] on an entity if you're going to give it a custom physics model.

Bullets can hit it now, however collision bound is still same.

Maybe a think would update it like this:
[lua]
function ENT:Think()

local min = Vector(0,0,0)
local max = Vector(50,100,50)

-- Rotate min and max.

self:SetCollisionBounds(min,max)
end
[/lua]
But I have no idea how to rotate a vector.
