Hi Burr - for speed, I would think that your method there is going to be the fastest since you get the right snap point after creating just 1 construction line.

Not much room to get much faster than that...

Thanks Michael and Burr !

From what you guys showed there I ended up refining it a little further :)

Type the angle, one construction line.

Just to be clear, if I was going to do any kind of isoscele, I would have to go out to the backyard and dig that guy up and take his bones far, far away! :O

This old thread is the first Google result for "moi3d construct tangent", so I wanted to put a tip here that I just found out:

If tangent snapping does not work ("Tan" doesn't appear) it's probably because the point at which you started the line is part of three-dimensional geometry and the point and the circle are not aligned in the third dimension.
