Problem

Hi, i've noticed problem with 3d cursor alignment. If we are working under object mode and want align our 3d cursor by object surface, orientation it totally wrong.

I've find way get around this problem, waht we need to do:

1. For first we must dive into edit object mode,
1. then selected one element of object 'Face, Edge or Vertices'
1. switch on 'transform orientation' on 'Normal'.
1. turn on our move 'GIZMO'
1. and for now if we to align 3d cursor with snaping by any area of model, we will get correct 3d cursor orientation by normals

I recorder short video with it and attached few screenshots.

Shouldn't you use Orientation: Geometry instead of Transform in the 3D cursor tool settings?

Nope, it's doesn't matter what mode of 3d cursor are you using, under object mode it's doesn't work

Closing this as resolved because the issue is gone in 2.80.60

You need to set Orientation: Geometry as @JacquesLucke noted

This is problem still here. Just try apply transform after rotation and then aling you 3d cursor to surface.

Can confirm that cursor doesn't respect quad orientation on randomly rotated mesh that has applied rotation.

The normal is correct however it's rotation along it's axis is seemingly random although it's the same angle for the same planes.

Correct behavior would be to copy rotation of the underlying meshes' normal.

Check #69603 for further information when it comes to Edit Mode / Snap Cursor to Selected. These problems are highly likely linked.

Working on a patch to get the 3dcursor in line with the editmode face transform gizmo...

There is a WIP patch D5885: 3D cursor tool: improve rotation for Orientation set to 'Geometry', but needs a bit more work (needs something like BM_face_calc_tangent_auto but without relying on BMesh...)
Setting as TODO, since it is not really a bug, hope to look at it again soonish...

Will have to concentrate on triaging for a while (and step down).
