Snapping to a tangent

[NigelShaw]

Hi,

i know you can snap to a tangent but i need to create a 3 point circle that is defined by snapping to 3 tangents. in other words, i am setting out a curved unit. i have 3 exterior circles to create the outside curves and i need to fit 1 circle that fits to the tangent of the three other circles to create my inner curves running off the tangent.

how can i do this?

regs,

Nigel,

Using the 3 point mode draw a circle from the centers of your 3 existing circles. That new circle will give you the center axis from which to draw lines back to the 3 origninal circles where the intersection of the the new lines of axis will determine the tangent points for all three circles.
