John,
There are more options beside ‘Isometric’ projections.
And even a solution for projecting inclined/rotated planes: Isometric Projections from Non-square Drawings
I’m not sure if the CAM 3D view is a vanishing point perspective, if that’s what you’re looking for.
That is also not the case for Perspective.gif in the example of Husky.
I know that my CNC driver CAM preview has such an option.
For illustration, one can always change the colors of the image itself. 
One can even set ‘black’ as transparent color so that the background is the page or paper background.
Regards,
CVH
