<h1>FitMesh mesh,x#,y#,z#,width#,height#,depth#[,uniform]</h1>
<h1>Parameters</h1>
<table>
<tr>
<td>
mesh - mesh handle
<br />
x# - x position of mesh
<br />
y# - y position of mesh
<br />
z# - z position of mesh
<br />
width# - width of mesh
<br />
height# - height of mesh
<br />
depth# - depth of mesh
<br />
uniform (optional) - if true, the mesh will be scaled by the same amounts in x, y and z, so will not be distorted. Defaults to false.
</td>

<h1>Description</h1>
<table>
<tr>
<td>
Scales and translates all vertices of a mesh so that the mesh occupies the specified box.
<br />
<br />
Do not use a width#, height# or depth# value of 0, otherwise all mesh data will be destroyed and your mesh will not be displayed. Use a value of 0.001 instead for a flat mesh along one axis.

; FitMesh Example
<br />
; ---------------
<br />
<br />
; In this example we will demonstrate the use of the FitMesh command.
<br />
<br />
; First we will use FitMesh on a semi-transparent blue box. This will represent the dimensions we will
<br />
; be using with FitMesh.
<br />
<br />
; Then we will use these dimensions on a red cone, so that it appears to fit inside the box when the
<br />
; space bar is pressed.
<br />
<br />
; The first time the space bar is pressed a uniform FitMesh will be performed, which means the cone
<br />
; will be scaled equally along all axis so that at least one axis fits the dimensions specified.
<br />
<br />
; The second time the space bar is pressed a non-unifrom FitMesh will be performed, meaning the cone
<br />
; will be scaled non-equally along all axes so that all axes fit the dimensions specified.
