For related X, Y, Z fields of Location, Rotation and Scale in the Transform panel of the 3D view 'N-Region', there is a possibility to change the 3 fields at once. It can be done with the mouse or with numerical input.

enter image description here

But it seems 'Dimensions' fields behave strangely (entering individual values works as expected). Sometimes the value is lost after being entered, sometimes only two fields are changed. An example:

enter image description here

  • When using the mouse, Y is left unchanged (expected: All values adjusted in proportion).
  • The final dimensions X and Z are different (expected: Final values are starting values times the same factor).
  • When entering the value 5, the result is 2 (expected: 5, whatever the scale value).

Is this a bug? If not, what is the reason to prevent this single input?

Using 2.79b.

    $\begingroup$ Good catch, Probably classified as a bug or over site. C.object.dimensions = (5, 5, 5) in py console works as expected. $\endgroup$ – batFINGER Aug 22 '18 at 17:06
  • $\begingroup$ It is not a bug, it is a known limitation, dimensions values are actually a hack and don't work with click-drag $\endgroup$ – Duarte Farrajota Ramos Aug 23 '18 at 1:26

It is not a bug, it is a well known limitation of the current system, as you can see in the bug repot.

Object dimensions are broken and an abuse of RNA, IMHO - the same problem happens from Python and we had it reported too.

Basically they rely on one axis being set, then updating - before the other values are set.

  • $\begingroup$ Thanks. A more recent activity here. Too bad the UI allows something that is known to be broken. RNA presentation can be found from here. $\endgroup$ – mins Aug 23 '18 at 10:13
