Ruler (like photoshop ruler)

May 31, 2014 at 6:53 AM
I need a ruler in my project for helixviewport like Photoshop Ruler in 2D(in zoom values change to cm and then to mm).
Could you tell me where i should start to get this approach?
Is there any built-in element in helix for this?

i mean by ruler is like this in 3d space with zoom and move (not rotate) , finding measures for an image or a plane.
