# Z-Axis or Metric Unit gives a worng size to any Object

I've found a very interesting problem in the Blender Editor and I can't figure out how to solve it. So I want to ask you.

I want my Object to be one Meter long on the Z-axis. The Problem itself is a simple mathematical thing: When I tell the editor to move my object 1 meter up (so on Z axis 1.0 m) then it moves the center point (orange) 1 meter up, on which my object is fixed. At the same time, I want that my object has a length (also on the Z-axis) of 1 meter. But how is this possible (picture)?: My center point is in the middle, so if the orange point would be on the green y axis, then it would be Z 0. But how you see, I've already set it to 1 meter. But the object is 2 meters long. Which kind of wrong relation is that? Or did I make sth wrong? The distance between the orange point and Z 0 is 1 meter. But the end of my object is again 1 meter above the orange point so it is 2 meters long even though I typed in 1 meter? Please help me out. It really confuses me.

• Where have you typed 1m? "even though I typed in 1 meter"? – lemon Oct 22 '20 at 13:15
