Edge length

Support Basics & Interface

Hi

I am using blender 2.69 (tar ball downloaded from blender.org) under a current SuSE Linux.

I wanted to know the length of an edge so I activated “Mesh Display”->“Edge Info”->“Length”. Blender showed me a length of 50.048 cm. I found that strange so I placed a cube beside the edge, stretched it to same length and checked what length blender showed me for this one … 3.726 m.

Is that a bug? Am i doing something wrong?

Here some screenshots:

This is how I placed the cube

And here the different lengths.

Apply object scale (in object mode obviously) with Ctrl+A -> scale.

Yes, that measurement of edges is NOT affected by the scale of your object.

If your scale is (1,1,1), then the mesh edge lengths will be correct.
But of you scale your object to 3 times its size, while you expect the lenghts to be 3x bigger, they won’t be, because mesh data hasn’t changed, only object scale !
Do you get it ?
It’s a bit weird at first, but it does make perfect sense in fact.

So that was what it was. thanks for the help.
