Useless trivia : quant = quake unit

Now you know

I think that one quant equals one and a half inch (1-1/2) in WED. The inmate character is over 16 quants tall when the small grid square is set to four units.

you can adjust the size of the grid, so you cannot give absolute size for absolute measurements

Is the measurement system in Game Studio based on metric or USA measurement system? A 3D character is about 17 small grid units or just over two large grid units in WED. I think that one small grid unit equals 6 inches and one large grid unit equals 3 feet. If I create a 3D model in a 3D modeler like Blender and Milkshape, how do I set up 3D modeler so that when I export the 3D model to MDL file and load it into WED, the 3D model is of the correct size?

Well, since Gamestudio is your target in your production chain, you should make the measurement there. So, lets say, you decide for 128 quants = 1 meter (or whatever you measurements looks like). Then make a cube that is 128x128x128 and save it as MDL mesh. This is your reference for your modeling work being imported into gamestudio. Now export the mesh to a format which can be read by your modeling application (e.g. FBX). Check your import/export options in your 3rd party app so that the import/export scale is matching the reference scale when you import the models into gamestudio (if you are unsure just import the cube and export it again and load the exported file into MED and check if the cube is again 128x128x128). Use as less convertions as possible.

If i createt a Level in Valves Hammer Editor i look into the Object Preferences for the Heigth. First i create a Player Entity(Height the same as the cbabe Model). The in Make a Wall Taler than the Player Entity. My thougth is, that the Player Entity is 1,80M Tall(In height Position = 72).
So the wall is 2,4 Meters Height. This is the Optimal Wall Height for maybe a Room.

In Quants it is(Grid=16(Checkthis in the WED->Preferences)

--- First Value = Height Position ---

32 = 2 Quants (0,6 Meters)
64 = 4 Quants (1,2 Meters)
72 = 4,5 Quants (1,8 Meters (If this Value changes, the Quants System fit to the Meters Values!))
128 = 8 Quants (2,4Meters)
256 = 16 Quants (4,8 Meters)
512 = 32 Quants (9,6 Meters)

EDIT:
Textures fit to this "Quants System"

This is my opinion about Quants...

For my indoor level I used 1m = 128 quants. It allows me sufficient details.
For the rooms this gives me realistic values with:

Roomhight old house 3m = 384Quants = 3x8small boxes = 3 big boxes

Thickness betwwen ceiling of one room and floor of room above = 0.5m = 64quants = 1/2big box
half of it gives me thickness of ceiling and thickness of floor for each room: 32 quants = 2 small boxes

Wall thickness outer wall =37.5cm = 48 quants = 3 small boxes,
Wall thickness inside, load carrying = 25cm = 32 quants = 2 small boxes, gives me 1 small box per room

stairs: 1 step = 25cm high = 32quants high = 2 small boxes high
1 step = 31,25cm deep =2,5small boxes deep

And then I did the same like HeelX: create a reference cube 1x1x1m = 128x128x128quants and export it to my other modelling tools as "urmeter"
