I just want to bring this up in case if you don't know: you can't use the Translate code for that because you only use that code to move objects, not scale them (the word "translate" here means "to slide" or "to move"). But I see where you're getting at. Unfortunately, I don't think there's a scale command or any other similar command, so you'll have to manually code the change yourself. It's tedious, but after you spend a lot of time coding objects you'll get used to it.  :)

OpenBVE uses meters, keep that in mind.

To save some time, use the replace feature (ctrl+H) on notepad.

Last line in B3D files to rescale|rotate an entire object:
SCALEALL +|-X,+|-Y,+|-Z

To scale an entire object to 90% of original size:
SCALEALL +0.900,+0.900,+0.900

To rotate an entire object 180deg around the Y axis:
SCALEALL -1.000,+1.000,-1.000

So there actually was a scale command! I guess I should have looked at the Developing for openBVE page instead of relying on my memory.   :P

But HijauKuda, why use the Scale command to rotate the object when there's the Rotate command?

so if the car is IND BMT length and IRT width do i scale all 20%

...why use the Scale command to rotate the object when there's the Rotate command?

If you require scaling, say 90%,
and simple 180degree rotation, then use:
SCALEALL -0.900,+0.900,-0.900
to save writing an additional line of ROTATEALL code.
This is equivalent to:
SCALEALL +0.900,+0.900,+0.900
ROTATEALL 0,1,0,+180.0

If you require scaling, say 90%,
and an odd angle rotation, say 30degrees, then use:
SCALEALL +0.900,+0.900,+0.900
ROTATEALL 0,1,0,+030.0
