By default blender allows you to scale past 0 - how do I prevent this?

i.e. it's common in other 3D modelling software to resize a set of vertices against an axis to align them - however this isn't possible when negative scaling is enabled.

As far as I know this isn't possible, use the keyboard input instead.

After pressing S for scaling use the keyboard to enter 0 (zero) to perfectly align geometry and optionaly choose an axis of alignment by pressing either X Y or Z.

  • $\begingroup$ Well that's arguably quicker, and the goal with that workflow is always to hit exactly 0, so I won't complain; thank you :) Would definitely be nice to have that option though, was the first tickbox I located when picking up Modo. $\endgroup$ – Nathan Hornby May 25 '16 at 16:05

    $\begingroup$ This can probably be achieved relatively easily with some sort of python script or a simple addon, but that is beyond my skills $\endgroup$ – Duarte Farrajota Ramos May 25 '16 at 16:22

    $\begingroup$ This is the best way to do it, but if you need to scale to a different limit than 0, you can press Shift while scaling, this will make scaling smooth enough to get an accurate result, you can use Shift with rotation an translation too. $\endgroup$ – Georges May 25 '16 at 16:57
  • $\begingroup$ This is not an answer. Scaling with the mouse is always useful IN-ADDITION to the mentioned method $\endgroup$ – portforwardpodcast Jun 23 '16 at 5:59

Select the mesh in OBJECT mode - Object Tab - Apply cntrl A - Rotation & Scale.

The error is coming up because when you're unwrapping it, it doesn't like the rotation and scale.

IDK how I just figured that out myself considering I was looking up the same issue and remembered scale can mean the rotation/scale/orgin of a mesh as well.
