Determine the angle of vectors at a node

Carbide Create doesn’t have a feature for this — you have to do the underlying trigonometry, or draw the tangent at right angles, then rotate the circle and the other geometry (but if the circle is a circle, it won’t rotate unless you perform a node edit or Boolean operation to make it into a curve).
