Blender for Engineering: Numbering and naming objects in blender I am working on technical drawings with Blender using MeasureIt. I am following  for making blueprints of specifical parts this youtube tutorial, and it works great.
 But when I am producing "big picture" drawings where I want to show the numbering and naming of different parts -which I'll produce blueprints of-  of e.g. a motor, I have to do it in PowerPoint. But this I think is a bit shabby. I wonder if there's a way of doing it in Blender? 

I'm thinkink about something in this fashion, with a legend:
That's what grease pencils are inicially for. However, I don't think there is any way to type in text although there are some addons (I never tried  this myself) and discussions.
