Hi! I'm a beginner learner and I'd like to know how to snap these three objects. I'd like to snap the two cylinders with the different faces of the cube. The short one on the left and the highest cylinder on the top of the cube. I'd like to have the center of the cylinder aligned with the center of the cube (the base of the cylinder inscribed into the face of the cube) I'm sorry for bad explanation I hope someone can help me Thanks!

I add a screenshoot in which you can see what I have to do

Thanks again if someone can help me with this!

A route to snapping aligned face-center to face-center for arbitrarily skewed objects via an intermediate parent...

Set Transform Orientation to 'Cursor'

  • ShiftSpacebarSpacebar go into the 'Cursor' tool. In its N > Tool tab settings, check 'Surface Project', and Orientation: 'Geometry'
  • Drag the cursor over the source face until the orientation catches.
  • In Edit Mode, select the source face, and ShiftS > 'Cursor to Selected'
  • ShiftA create an Empty, with its creation orientation set to 'Cursor'
  • The Empty is the wrong way round, so RX180
  • CtrlPparent the source object to the Empty.

enter image description here

  • In the same way as you aligned the cursor to the source face, align it to the destination face.

enter image description here

  • Empty selected, (Header) > Object menu > Transform > 'Align to Transform Orientation'

enter image description here

  • ShiftS > 'Selected to Cursor'
  • Source object selected, AltP Clear Parent and Keep Transform.

enter image description here

This would be a whole lot easier if ShiftS > 'Cursor to Selected' automatically aligned the cursor to the selected geometry, when the cursor tool was set that way. We should appeal to the devs. for that.

I don't know if there's a faster way:

  • Put the origin of the object you want to snap on its bottom face (first in Edit mode select the face, put the 3D cursor on the face with a Shift S > Cursor to Selected, then in Pose mode set the origin to the 3D cursor (header menu bar > Object > Set Origin).

enter image description here

  • Enable the Snap with these options: Face mode / Align Rotation to Target / Project Individual Elements.

enter image description here

  • Snap the cylinder on the face you want.

enter image description here

  • To align the cylinder on the cube, select the cylinder, then the cube. The cube being the last selected, it is said "active", it has a yellow line all around.

enter image description here

  • Go in the header menu bar > Object > Transform > Align Objects.

enter image description here

  • In the Operator box (bottom left) choose Relative To > Active and the axis you want your want your object to be aligned with (press Shift to select 2 objects.
