Unless I just haven't learned yet how to do it, I think I am missing the possibility of snapping a circle radius when drawing one. The two handles to the top and the left do snap, but I found no way to snap to the bottom, the right or any other direction. This matters, because the radius of a circle sometimes depends on snapping to the surrounding nodes, paths or objects.
For clarity, please look at the attachment image.
As may be derived from the attached image, there are cases where the ability to snap the radius of a circle in other directions than left or up, can be instrumental to the creation of an object.
I suggest four possible solutions:
1. Make the start and end points of the segment, arch, full circle or ellipse snapable too.
2. Allow users to pull the nodes over the center point of the circle, allowing to pull the radius to the right or bottom of the center point. This solution would still not allow for snapping in any other direction than left, right, up or down. Therefore I do not recommend this option.
3. Allow for the rotation of the circle object while still drawing it, so the handles can be positioned in different orientations.
4. Allow for snapping of the circle outline{path), while drawing the circles radius.
I will be monitoring the ticket, any questions or suggestions please feel free to comment.
ADDITION:
this ticket is about snapping the radius of a circle or eclipse. the same lack of a snapping feature however, occurs when the radius has already been determined, but the user wishes to snap the starting and ending points of a segment or arch. Please attempt to find a solution which solves both these issues.
I think what you mean is that you cannot snap the circular handles that can be used to determine the opening angle of the circle segment / arc ?
