I am a new user with blender. I need to draw some scaled shapes as in AutoCAD. For example I want to draw a line from (0,0,0) to (5,5,5). Or I want to draw a rectangle that’s up-left corner stands on (0,0,0) and down left corner stands on (-5,0,0) and so on. What is the practical way to do this? I always use scale (S). But I think there is another way.
