Now, I am almost certain this is impossible, but my dad is trying to learn to use blender. I keep telling him this is impossible, bt he's a stubborn old git () and he's forcing me to ask on these forums for some reason.

Okay, is measurement possible in blender? Like actual millimetres or centimetres?

Cheers, Toasty

Actually no, I've found that you have too make it up instead or this method:

Google:
Quote: "If you go to the View menu and select View Properties, you get a control panel that, among other things, controls the behavior of the grid in Blender. You can define the size of each grid square and the size of the "grid floor" in perspective view, but most importantly you can set the number of times each grid square is divided. So if you're working with feet and inches, you can change this to 12. On a smaller scale, you can change it to 8 or 16.

Blender strives to be "unit agnostic," and for modeling and rendering purposes, it mostly succeeds. You can work on any scale that works for you, that is appropriate for your current project.

If you start using physics simulations, you might want to think about working on a consistent scale, like 1 BU = 1 Meter. "

Blender uses 'units' these units being nonphysical 3d space can be any unit of measure you want as there is nothing other than what you add to reference to.

if you press the n key in object mode you get a transform properties box with the field: dimensions.

the starting cube measures 2.000 units you can consider this to be 2cm or 2in or 2km it doesn't really matter as long as you use the same unit of measure for everything you add to the scene.

also if you want to shape something to a specific known size you can edit the dimensions directly here in this box without having to scale by % or snapping to the grid.

Blender is not "Impossible" in-fact after about 1/2 hour of tutorials from "Blender: Noob to Pro", you're ready to go once you forget about the completely vampiric sub-surf, that stuff will kill your models. You'd also of course need to look up more stuff, mainly about constructing faces (selecting 2 verts to make edge/ 3 or 4 to create faces) and using the cut tool (K with operation faces selected). Along with spliting objects (P) and rejoining (CTRL+J).

A unit in blender could be anything you wanted it to be, from a millimeter to an AU. If you assume that one Blender Unit is one meter, than sure, there's measurement. Is he wanting to use Blender for CAD or something?

Most modeling packages come with the ability to set the unit sizes. they can be any size of measurement you want. Also most 3d apps come with a vector ruler function. Set two points and get the distance between using the set measurement.
