System Information
Operating system: Linux 5.3.12 (Manjaro stable)
Graphics card: None (internal intel HD 4600)

Blender Version
Broken: 2.81, 2.82 (sub 3), branch: master, commit date: 2019-11-30 17:33, hash: f1ac64921b49
Worked: I don't know

Short description of error
Chooses coordinate axes on tool settings does not affect on location transformation object at sidebar.
If selected to rotation, scaling instead location, issue does not playing
Please see video

Exact steps for others to reproduce the error

  1. Change pivot point (origin) location of any object
  2. Select Local axis on toolbar settings
  3. Select location transformation on sidebar and move object to another place. Object will be moved ONLY by global axis, don't by selected Local axis (or any other axis)

Hi, thanks for the report.

This is working as intended. The numerical transform properties tab only changes the global transform properties. Internally the transform is applied in order Scale, Rotation, Location, and this is why scale seems to follow local transform. The reason the rotation appears to pivot around the local X axis is because the rotation mode is set to XYZ Euler. If you set it to something else you can see it will use a different rotation axis first. If you want to move the vertices by the local transform numerically you can do so from in edit mode. There is an option to switch between global and local.

Archiving since there is no bug here.

Hi! Sorry, I don't understand, then why not possible the Rotate to rotate by global axis? I selected any other mode Euler and object don't rotated by global axis. It is very strange that the Rotation is of the local axis, and the Location of the global axis. It is really not a bug?

The numerical transform are base properties for the object. Each object has one set of them in order to position them in the world, and they are applied in the order I said.

You can transform object by other transform orientations using the transform tools, but they still are converted to these base properties in the end. For instance, you can set the object z rotation to 45, then set transform orientation to local and press G and then X to move along the objects local X orientation. But notice when you do that the base properties changes both x and y. So in a sense all the other ways to transform the object all have to be translated into the base properties. None of the other numbers are saved, only the base transform properties.

You can also rotate using global axis, you just have to use the transform tools set with global orientation. They will rotate using a global axis and translate that back into the base transform properties.

If you want to be able to numerically change the numbers when doing other transforms first do a move, rotate, or scale and then open up box in bottom left, you can then enter any number you want or even set different orientation.

Ok, it is good. I understand why this is necessary.
I don't understand, why the Dimension, Scale, Rotation don't change object also by global axis as the Location? :)
Anyway, thanks for the answer, maybe I will better understand your answer later
