To make several vertices co-planar, the usual way is to use Scale = 0 along some convenient axis, but sometimes there is no convenient axis, e.g in this case were I placed the vertices using polar coordinates:
How to make the selected vertices co-planar again after they have been a bit disturbed. The target plane contains the global Y axis and the average angular position of the selected set.
I understand I could rotate the vertices around Y, so that they are roughly aligned with Z, then use Scale X = 0. That's what I do, but I'm looking now for a more accurate and less fastidious method.
In a more general way, is there a method (I assume this would be a addon) to facilitate work when dealing with object constructed by angle-distance rather than distance-distance. For example a method which would allow to move the selected vertices radially by the same specific distance (e.g. move each vertex away by 2 cm from the center of the object) while keeping their angular position unchanged?
