I have an 2D object (eg. circle) and would like to modify single vertices and their angle. Very much like in any graphic software I would like to select one single vertice and convert it either in a hard corner or a "soft"/smooth corner. Couldn't find that in Blender. Proportional editing and smoothing won't work.
Related to this question I would like to manipulate vertices by exact dimensions and find that sometimes this is hard to achieve. For example I would like to scale by an exact dimension.
