Is this for controlling a CNC machine?  Take a look at G-Code.  You can find 
tools to write G-Code, but I think something like this could be coded by 
hand.  Next, you should be able to find a G-Code viewer, which will draw the 
results of the G-Code program on screen.

This guy http://softsolder.com/ uses G-Code a lot and puts code snippets on 
his web page.

Alternatively there's OpenSCAD http://www.openscad.org/ which is a 3D 
programming tool.  Type in your program and get a 3D rendered drawing.

Unless I misunderstood your requirements entirely.
