I want to move a vertex from a 3D Cursor in a direction (vertex - center) ie from the cetner outwards.
I know I can achieve that with scaling the vertex position against the 3D cursor, but when moving the vertex by 1 unit I have to deduce the unit from distance.
When the vertex is 3 units from the 3D cursor and I want to move it by 1 unit. I have to scale the vertex by 1.3333...
Is there a better way to do this ?
