Measurements tool script

I am picking this script in user preferences but i can not see it in blender.
Am I doing sth wrong or it is not working?


Where are you picking that from? The only one I see is:

3D View: Measure Panel

It shows up at the bottom of the ‘n’ sidebar thingie in the 3D View (hit ‘n’ and it shows up; hit ‘n’ again and it goes away). You may have to scroll down to see it.

Disclaimer: I have no idea what the panel does and so don’t know if it will serve the purpose you have in mind.
