What's Tech draw ?

I’m reading the release log of the 2.37 and it mention this “Tech draw”.

What is it ?

(I’m dreaming about cad features…dynamic snap…etc…)
( nothing new about this kind of features ? BlenderCad ?)

thanks

“Tech Draw” options: for display of edge length, face corner angles and face area

With an object in edit mode, press F9 and look in the Mesh Tools 1 panel. There you’ll find these new options.

comming from experince in AutoCAD, I’ve always expected to see something like this in Blender… Maybe more technical drawing techniques for more releases.
