| Oct 14, 2016 at 10:23 | comment | added | Arjan Singh | Detecting Mouse Clicks isn't an issue but if you watch this video you'll understand what I'm trying to say youtu.be/0B_IQK7hMo0?t=2m8s watch from 2:11 to around 3:00. If you notice the technique in which he draws, when he still holds his mouse down after the click he can tune the curve just by moving the mouse. That is basically what I am trying to implement... | |

| Oct 14, 2016 at 8:19 | comment | added | Simon F | I suspect that, like myself, many of us don't have Illustrator, so you'll have to be more specific in your description. Are you just clicking to define the end points of the each curve segment and then moving the end point(s) of the tangent associated with an end point? | |
