Hi Michael.

Hopefully this video shows what I'd like to speed up a little. https://vimeo.com/817813423
Currently, I draw radial construction lines in the circle and trim the circumference to them, this then allows me to place the required lines at the correct angle, but it's a bit long-winded.
What I would like is for the line I'm dragging in the video to be able to snap at a tangent/perpendicular to the circle.
Sometimes I know the angle of the line in respect to the circle, but don't have a definite start point for the line, hence the problem.


Thanks.
Martin.
