I'm on Blender 2.79 and could not figure out how to set distances between vertices(or anything) in Blender. I'd like the distance between the two selected points in this image to be 77cm or in my .blend file 0.77 Blender units.
I can measure this distance with the protractor and move the two vertices, but if I'm just moving them by hand it will never be exact. I want to be able to enter a number in a box somewhere, and it to be the distance between them. How do I do this? This seems to me like one of the most basic features of any 3D design program, but I can't find an answer on the interwebs.
