[Bf-committers] Snap Selection to Origin - pointless operator?

[Matt Ebb]

Hi,

I was investigating this bug report today "[#21760] Snap to Origin
doesn't work" [1]. Its behaviour is a bit odd, in edit mode and object
mode basically it's the same as scaling the selection to zero. Current
behaviour with armatures in pose mode is even stranger, it tries to
put the selected bones on top of each other, and repositions the
joints in order to make them fit a bounding bug.

I thought this current behaviour was a bug, since by the name I
thought this operator would offset the selection, so it's centered
around the origin (i.e. if you have a mesh that's been edited and
moved away from its origin, you can snap it back so that the shape is
preserved, but it's now back at the object origin). To my surprise, I
found the current 'scale to zero' behaviour is intended and has been
like this in in earlier versions too (2.49, for one).

Personally, I think the current behaviour is pretty pointless (scaling
to zero) and this tool would be much more useful if it did what it
seemingly advertises - offsets the selection to it's around the
origin. So, I'm curious to see if anyone actually uses it, or has any
other insights into why the current behaviour is useful. Otherwise I'm
happy to either remove it entirely, or change it to the offsetting
behaviour that I mention here.

cheers,

Matt
