Let's say I have three identical meshes, but some of them are rotated as shown in the image:

enter image description here

Now in edit mode, I want to move the face to change the size of the mesh, what are possible workflows for the mesh to resize? See the arrows I drew in the image. I want the face of the mesh move relative to its object. I tried experimenting with parenting object, shift+G (select face by normal/coplanar) etc.

I am stuck. Hope I explained myself clear.

If you want your meshes to remain identical for a while during modelling, or permanently, but with different orientations, they could be AltD instances of one another, instead of ShiftD copies of one another..

enter image description here

For entirely separate objects, in this case, you could set the pivot to 'Individual Origins' and the orientation to 'Normal'.

You can edit multiple meshes simultaneously, using GZ to translate faces along their normals, averaged per selection-island:

This can be simply achieved by the following procedure:

When in edit mode, select the faces you want to extrude, and set the transform pivot point to individual origins:enter image description here

Now, when you extrude, you get this result:enter image description here

Now if you don't want the edges, you can select loops by double clicking on them and press X>Dissolve Edges.enter image description here

    $\begingroup$ +1 .. but it doesn't need to be an extrusion followed by a dissolve.. if you don't want the extra edges, then as well as setting 'Individual Origins' you could also set the orientation to 'Normal', and use GZ on the faces. $\endgroup$
