We could tweak the settings for the BSpline approximation once or we could make them available as Parameters in the DrawingGui preferences. |
|
|
Allowing to use different values for the approximation is troublesome because you will always find an example where the approximation works but badly fails for another one. IMO, it might be better to have a function that checks how close the spline is to a circle and if it's close enough compute an exact circle and use this instead. Therefore the spline can be discretized into three points first so that the center of the circle can be computed. Then the spline can be discretized into e.g. 30 points and if all of them have a distance to the center within a certain tolerance we can consider the spline as a circle. |

Please see http://forum.freecadweb.org/viewtopic.php?f=3&t=9289 This fix may have caused a new problem. |
|
|
Caused a regression when a line is represented as a b-spline curve. Then the circle check failed because the curvature center cannot be computed. |
|
|
is responsible for the reversed arcs. |
|
|
changed the severity to blocker, as this created a regression which is trivial to workaround for the 0.15 release. git://github.com/5263/FreeCAD bugfix-drawingarcs |
