New script: 3D guidelines

[Terry Capps]

I use ac3D to model electrical or mechanical projects that I am designing before actual construction and find the 3D Guidelines script invaluable.

I ran into trouble when I attempted to use the "3D Guidelines" with ac3D 8.0. I posted the problem that I had in the AC3D General section of the forum. Andy responded and posted a new version . I checked it out on my system running Windows 10 and it seems to be working great!
