Oh whoops sorry Mike I thought you were asking for making those other apps go into Modo. You're talking about going from MoI into Strata though, right?

Most mesh formats do not have any way in them to label the unit system that they were created in, FBX is one that does though. So you might try FBX again with Strata.

Otherwise, it depends on the particular behavior of the specific app, maybe they have an option that you can set that will tell it what unit system the .obj file was in and sometimes they scale objects to what they figure is just a generic convenient size and you'll need to set an option to turn off that behavior to be able to get the size preserved at import time. I don't know the specifics about how Strata behaves in this regard.

I use multiple 3D apps Modo, Strata and yes Cheetah. This scale thing always seems to come up. It really comes down to the math of scale proportions I suppose. I think Modo uses 1 unit=1 meter. In Strata 1unit=1 point or 1/72 of an inch.

Hi Mike, so if Strata interprets the .obj file coordinates as being points, and you have your MoI units set to inches, you will need the coordinates scaled up by 72 in order for them to translate properly into Strata.

You can either do this by using the Transform > Scale command in MoI - select everything, run Transform > Scale, type in 0 and push Enter to specify the world origin as the scale origin point, and then type 72 and push enter. Then undo after you have finished the file export.

Or another way that is more convenient is to go to Options > OBJ options > "Scale factor" and put in a value of 72. Then that scale factor will be applied to every .obj format export.

Thank you again.
