Many times I would like to know the length of a bone, not the xyz coordinates. Is there a way I can just click on a bone and view its length?
Not that I know of, but you can write simple scripts that gets the coordinates as vectors of the bone’s head and tail then use vector maths to get the length length = (v_head - v_tail).length
Cheers, Clock.
EDIT:
Like this:
I ran Blender from a terminal by the way…
Might be good to go in a “Bone Info” add-on maybe, if lots of people want this.
EDIT 2:
You can actually use this: print(arm.pose.bones["Bone"].length) - even easier!
see this in the API
EDIT 3:
Or, just look it up in Edit Mode in the N panel:
Hmmmmmmmm.
