I have a curve of points I wish to best fit a gentle very shallow arcing curve through, but it must start on the first point and end on the last point.
Q1) How is this done ?
I have used ControlPointCurve tool and drawn snapping to each point but I want to get the subtle wriggles out of this now. ( I could also have used right click on that tool and curve through points)
Q2) Also if with that shallow arcing curve drawn as such, I wish to alter its shape a little still keeping it arcing and gentle and smooth, and again it must start and end on the points, how is this done ?
F10 and pulling on the controls loses the smooth sweep, one is attacking parts of the curve without regard to its overall curve.
If I had drawn it in Freehand with its curve tools I could simply pull out the handle for the start of the curve and the whole curve would adjust.
The handles curve tool does not see the same handles show up when one edits a curve. (separate post on this discovery somewhere)
Q3) I also sometimes need to draw a best fit curve through points starting and ending tangent but the only curve tool I know that has start tangent doesnt do best fit. InterpCrv
