When I set Blender to metric units with scale '0.01' (centimetres) or any other scale, except '1', I meet a bug.

Sometimes, Blender displays some values in meters. If I click into value and then press Enter immediately, it changes units to centimeters, although such operation should not change anything.

It is a bug and it can be fixed.

One way is to adjust value after click. Initially it was 1.54844 m. Once clicked, it became 1.54844. Since absent units means cm, Blender should change the value to 154.844 immediately after click.

Other way is to retain unit in the window, but make it not selected, like windows do on file rename. Once I click F2 on file with extension, it selects name but extension:

  • $\begingroup$ Not everybody agree it is bug. So as me could not know it is bug until asked. Regard this as a question: is this a bug or feature? $\endgroup$

By default Blender interprets input at the base unit measurement in that system. All you need to do is to input a unit as well as a quantity and this will work as expected (i.e. 12m or 12cm etc.)

As you have noted in your question, changing the Scale option changes what this base unit is. In your case the base unit is cm, so for any other unit of measure, you must input that unit after the numerical input.

  • $\begingroup$ Yes I understand this, but anyway it is a bug, since I didn't do anything while Blender changed the value. $\endgroup$

  • $\begingroup$ No, it is completely expected. There has to be a default unit. All that is happening is that it is not carrying the units over when you edit them. You need to add them again. I agree that the feature you mentioned in your question should be added. $\endgroup$

  • $\begingroup$ I don't edit anything. I just click and confirm. No editing. This is blender who change the value, not me. It treats it inconsistently. $\endgroup$

  • $\begingroup$ I have read that you suggested to enter the unit explicitly which is not contradicting the point that it is a bug. $\endgroup$
