Cam Spline 1.0.0

Installation:
1. Extract the zip file to a folder.
2. Run 'camspline.mse' from the folder using MAXScript > Run Script...

What it does:
Cam Spline is an interactive spline tool which produces spline shapes based on two circles
joined by two straight lines, or a 'cam' shape. Cam Spline faithfully keeps the intersections
at a true tangent, regardless of the diameter of the circles or distance between them.

How to use:
The basics are really simple:
Each 'end' circle and the distance between them is controlled by their respective spinners.
Each of the four central vertices also has a spinner which will rotate it about a circle centre.

Thats all there is to it. The other buttons allow you to 'link' or 'equalize' certain spinners to
aid in producing symmetrical shapes.
Just playing around with it should give a good indication of what does what.
A help menu is included, as are a few basic shape presets.

Limitations:
At the moment Cam Spline can only CREATE in the TOP viewport, but can be moved in X and Y
AND rotated about the Z axis.
Movement in Z or rotation around X or Y will reset the spline to zero on next spinner change.
Rotation about X or Y is reserved for a later version.

'Holes' are not interactive with any 'extrude' modifier you may add. They will only show once the spline
is 'finalized'. This feature is reserved for a later version.

Using 'undo' will probably crash 3dsMax. We dont think you'll need to use undo anyway but
advise against using 'undo' on Cam Spline operations.

Due to the unlimited amount of different variations its impossible to error check every one, therefore 
it IS possible to crash Cam Spline. The spinners will read 100000 and stop working. Use the 'Re-' and 'set'
buttons to reset Cam Spline to its starting shape.
