My approach to drawing this cord was to draw the line longer than I needed, adjust its distance from the tangent, then trim the excess. After I do this (and the trim places dots where the cord appears to meet the circle) and regenerate, I get an intersection and loop error (both unhealable). If I zoom in on the cord ends, I can see they're not on the circle. If I try to trim again it wants to delete the whole cord. What am I doing wrong? Thanks.
