I am a hobbyist 3D modeller and would like to select a vertex\edge\face and move it in one\several axis by typing in a offset number that will +- increment the selection. For example if a vertex is 10 on the x axis I want to be able to type in say 2.5 to move the vertex to x:12.5.
I have used 3D Studio Max and this capability is available by toggling a button that is left of the x,y,z type in coordinate boxes:
Does Blender have this function? I have tried googling for an answer but I have not found an answer.
