I'm using 3DS Max Design 2012

I modeled a 100cm^3 cube and exported it to the engine.
As you can see, the cube is a little less than 1/2 the size it should be...

In max my units are in cm, just like the documentation suggests...

Any idea why?




Im also getting weird proxy issues where the proxy is like 10m in a random direction from where the object is located.

ok, so i switched to regular 3dsmax and the problem is still there. But only sometimes.

the small frige is the size it is imported by max
the big one is the size it should be inside of max.

a 1x1x1 m cube is next to it for comparison

units are set to cm inside max...


please help, this is driving me crazy

You prolly did these already but just to make sure:
-Reset XForm
-check 'export file per node' and uncheck 'merge all nodes'
-convert to editable poly
-try attaching the proxy if you haven't done so

That's all I can suggest.

thanks, but nope...

Anyone else? I feel like this is a fairly common problem.

In your screenshot showing Display Unit Scale, click the System Unit Setup and put up a screenshot of that popup.

Yeah, you should check the System Unit Setup window and make sure that it is also set to the same units. The display units scale that you showed in your screenshot is only used for what gets displayed next to numbers in max.
For example, your system units could be set to inches, but the display units is set to cm. This makes things very confusing as everywhere you see amounts in max it will say cm, but in fact it is actually inches instead. Always check to make sure that the display units is the same as system units unless you specifically want them to be different for a particular purpouse.

Are you still experiencing problems with this?
It sounds like a scaling issue.
Convert your box to an editable poly - UNLINK everything - and then do a Reset XForm on everything.
You can link things up again after that.
Export and it should be fine.

I'm having the same issue but this didn't fix it

Can someone with this issue attach their source files and note the expected sizes please?

I'm eyeing it rather than being spot on measurement, but according to the internet, an oil drum (my model) should be around 23" diameter x 35" tall

Here's the file

has anyone been able to solve this yet?

I tried to take a look, but the max file you posted would not open (I am using Max 2010).
Could it be that it was saved in a later version of Max, like 2011, 2012 or 2013?
Could you please resave it for Max 2010 (dropdown box with the file formats when saving as...) and then post again?

Alright, yeah I'm using 2012


Here's the new version

I tried and couldn't open your file with 2010.

@HWJohn: Are you sure you saved it for that version? I could not open it either.
