I'm totally new with blender, and I want to measure the space that is present between the center of an object and a second object:

the first object is a road, and this is its center: enter image description here

the second object is a rail, and I have to move it to exactly 9,012meters on the right of the y axis of the road: enter image description here

how can i place it measuring the distance with precision?

  • $\begingroup$ right :) moreover measuring it seems to be quite difficult, because i cant select the right place in 3D environment :D i have 4 view (its blender 2.79b) but when it seems i selected the right point, in the other views i see i went too "deep" :D $\endgroup$ – Don Diego Jul 28 '20 at 14:12

  • $\begingroup$ Wouldn't typing number when moving object do the work? Is there anything that is not possible to achieve? $\endgroup$ – HikariTW Jul 28 '20 at 14:36
  • $\begingroup$ well, typing numbers make the center of the rail stay at - let's say - 9m from the center of the squares plain; i am trying to put the left edge of the rail (the extreme left side of the rail) at 9m from the center of the road (orange dot) $\endgroup$ – Don Diego Jul 28 '20 at 15:15

One obvious solution seems to be snapping.

  1. Select the road, and put 3D cursor there (Object > Snap > Cursor to selected)
  2. Add > Object > Plane and set it's size to 9,012 meters. Now we have a measure.
  3. Enable snapping to Vertex > Closest.
  4. Move the rail along X axis and snap it to one corner of the 'measure' plane.
    It will be exactly 9m from the center of the road.

New objects appear at 3D cursor. My plane size is 400 mm. Your's will be 9,012 m. enter image description here enter image description here
