Move and snap object to another object in Blender

Situation: We have an object (a cube) which we want to move and stick it precisely to a particular point at another object (another cube).

AutoCAD analogue: We have two boxes. We say move, select one box, choose as the point of reference intersection at a corner, then move the box with object snap to the intersection at a corner of another box.

How to do it in Blender:

Basically we are playing with two elements here:

  • POINT OF ORIGIN of the object, the miniature orange ball you can see for the object which is selected. It is our “reference point” for operations with the object.
  • CURSOR, the little red-white dashed ring with the black cross (and not the bigger white ring with 3d axis attached, that is the 3D Transform Manipulator).

The basic idea is that we strategically place the cursor somewhere at the scene, and then tell Blender to move the object so that its point of origin coincides with the cursor. Obviously, the strategic placement of the cursor in this context means placing it at the corner of the box to snap to.

We have our two cubes.

01

Click right on the cube on the left to select it. 

02

Hit Tab to enter Edit mode.

03

Right click the vertex to select it. It is to become our “reference point”.

04

Hit Shift+S -> “Cursor to selected”.

05

The cursor moves to the vertex.

06

Hit Tab to Exit Edit mode and return to the Object mode.

07

Hit Ctrl+Shift+Alt+C -> “Origin to 3D Cursor”. (You must be in Object mode to do this or you will get an error message)

08

“The origin” of the object, the little orange dot-ball, moves to the vertex. It has become our “reference point”.

09

Now right click on the other cube to select it.

10

Hit Tab to enter Edit mode.

11

Right click to select the vertex which we will be snapping to.

12

Hit Shift+S -> “Cursor to Selected”.

13

The cursor jumps to the vertex. We leave it here. It will be our “target”.

14

Hit Tab to exit Edit mode.

15

Now all is set and we are ready to move the cube on the left and snap it to the cube on the right.

Right click the cube on the left to select it.

18

Hit Shift+S -> “Selection to Cursor”.

Please note: Previously we were moving the cursor to a selection, which was a vertex (we were in Edit mode, to be able to access individual vertices). This time we are doing the opposite, we are moving a selection, which is the whole cube (as we are in Object mode), to the cursor, which we left sitting at the vertex of the cube on the right.

19

Voila! The selected cube moves and its point of origin “fits with a snap” into the cursor.

Mission complete.
