This is a very good conversation to have, about scale in Blender. Blender's use of realistic scale has always made me confused. I know this is one area where even Blender guru, Andrew Price, has called the software broken. A lot of Blender users hate him for saying that, and I personally think he went too far by saying that, but in some respects, I understand what he meant. There have been a few times when I was modeling something to "scale", using Imperial or Metric. It's all fine and really good up until you need to do a modelling task to scale. For sake of example, depending on your scene scale, the parameters in Blender will display the units of measure as feet or inches, but not so in many of the modelling action parameters. What if we wanted to inset a face to exactly 1 inch. I suppose there's a way to measure that, but the parameters of the inset only show default numbers, and aren't counting by the set units of measure anymore. The same is true for other features in edit mode. I assume this is what you meant by "inconsistencies in the parameters", Luxxeon? Is there any way to fix this, or a way to accurately measure those parameters? Or do we just have to eyeball it when it comes to certain things? This has had me stumped for a while now, and frankly I'm a little surprised it hasn't been addressed in the software all this time. Especially now that Blender is being used a lot in 3d printing, and even very sensitive modelling like architecture.
