![]() Use the spline tool to create a curve that intersects the endpoints of those tangents.Make the length of each tangent equal to the length of it's respective chord - this will form the outer profile of the tooth.Repeat making these tangents for the rest of the points on the circle.Draw a tangent perpendicular from one of the points of intersection.Dimension the length of each chord and move these dimensions out of the way.Repeat making these chords for the remaining points on the circle so that you have 4 chords that share the same endpoint.Draw a chord (a line whose endpoints lie on a circular arc) from a point of intersection (between one of the radial lines and circle) to the furthest point. ![]()
