Tip: Measurement Units

In this quick Blender 2.5 video tip we show how you can change the unit of measurement within Blender away from the default Blender Units to either Metric or Imperial units. Doing this makes it much easier to accurately create objects to scale.

    I can see this coming in handy for the people who use shapeways.
    Nice tip.

    Is it possible when using an object with the particle system that these newly created objects can react to each other? think Reactor for 3DS. I’d like to use this to position things like a pile of tires or a plate of fries.

    You could also have mentioned the display of shape dimensions, which are available in edit mode, with the N toolbar.

    It displays edges length, face area and shape volume, which can be very handy.

    Is it also possible (I have not discovered a way to do so, so maybe it isn’t there) to display the sizes in the 3D-view constantly?

      1. Select an object and Tab into edit-mode
      2. Hit N to display the properties panel
      3. Scroll down to the Mesh Display panel and check on Edge Lenght

      That should do the trick.

      I’m not sure how to enable this for all objects at once, though.

    This tip is great! I like these tips more than I like full tutorials. I can spend just a few minutes and get some really helpful information every time. I’ll definitely start using this when I model stuff to scale. Thanks!

    pretty cool! I’d experimented with it before, though I haven’t really used it…but at least I know it’s there if I need it, right? 😉

    thanks a lot for these videos Jonathan, they’re always really helpful 😀

    The fact that all measurements over 3ft show only as yards when the Imperial system is used will be an issue for a lot of users due to the fact that yards are rarely if ever used in architectural, site or mechanical drawing. Even when converting ft/in to a decimal Blender shows the measurement in yards. I hope this slight oversight will be changed in future versions of Blender.

      This is a big problem for me. I would love the option to use only inches or only feet or both inches and feet without blender converting the number. I find myself spending way too much time converting measurements. It would be very useful for me if I input 48″ that it displays as 48″

        Yeah this is a problem for me also. It would be nice to hardlock the input boxes to always display inches. If anyone knows how to do this please reply to me. Thanks.

    I am interested in using Blender to create objects for 3D printing, as I am a new owner of an Ultimaker 3D printer. I would love to see a tutorial on the creation all the way to the actual printing of something, on any machine.

    The other options I have involve relearning new software (freecad, 123D), but as I am already getting familiar with Blender, I would like to continue by making physical objects with a familiar interface.
