[REQ] Shadow intersect

SHADOW INTERSECT

Same idea as the "Surface Operations" ruby tool "draw line on surface" and similar function as "Intersect line with model", but this works with a cast shadow on surface.

This would be good as it would allow in the Layout mode us to draw a more visable and highlighted line directly over the line cast by the shadows (which sometimes arent always that visable. It would also help when doing shading diagrams and allow us to compare extg bldg shadow lines with new building shadow lines.

We would then have a more visable line to trace once transfered to Layout.

There may also be other uses of this function. Can this be done??
