Keep a circle's shape when opening a small piece
Posted: Tue Sep 15, 2009 6:12 pm
This is a real basic vector drawing question. I've read on this forum that AS uses a different mathematical approach to storing curves. Circles are easy with AS. But how do we take a circle, and then but a small opening on one side of it?
It only takes 4 points to describe a circle. My attempt was to add points on either side of the spot where I want to open the circle up, hoping to remove the edge between the two extra points. But every time I add a point, the curve of the circle gets really messed up. Is there a way to lock the initial position of a curve?
I guess another approach would be using more points with the freehand tool.
