Have to nit pick a little hereLarry, the visualizer is not an invention. It is not novel and is not patentable. It simply uses existing technology to accomplish a goal.
The Definition of “novel” seems to describe the origination of the visualizer like a glove.
new and original.
“ novel: If something is so new and original that it's never been seen, used or even thought of before, call it novel.”
I suggest that using video and drawing on the screen to see where a cutter is inside a hollow form “was never thought of before”Trent did it.
