Good day
So I am working on a project which I need to use Moi and Nvil3d together.
The issue I am having is when I save to obj and import in Nvil is way off in size.
So I made 2 cylinders 157cm from center to center export as obj...import back in Moi and it is 10 times smaller. Moi dimensions are set in cm.
So where am I going wrong here?
So I guess I have an issue in Moi or in Nvil or in both lol.
and what is the difference in save obj and export as obj.
Tnx!

10x scale i a bit weird.
.obj doesn't store any unit system. When you work in cm in MoI, a box of 10 cm means 10 units. It's up to the .obj loader in Nvil to decide what to do with the unit (cm, m, mm etc).
If you create a 10x10x10cm centred box, working in cm in MoI, vertex should be between (-5.00,-5.00,-5.00) and (5.00,5.00,5.00). (.obj is a plain text format, so you can check it with a simple note editor).
So usually when you have scaling issue, it's often by 100, 1000 ... maybe Nvil default is decimetre ?
MoI have a few option if the export setting, like scaling factor, that can help to get a match MoI>Nvil ... but Nvil>MoI might still be off.
- Check if you can set NVIL default unit as cm (and check if there are any import/export options when it comes to unit conversion)
- Use .FBX (FBX format store the unit system, so loader can do a better scaling conversion)
"Save As" save the complete MoI scene, "Export" only save the selected geometries.

Ok I just did another test for some reason it seems good in Moi.
2 cylinders 20cm apart export as obj...import obj remeasure and it is good.

Something very easy to make! :)
Draw a line as any measure you want!
Say 1 meter
Import your OBJ
Transform / Oriente/ Line - Line
4 cllicks et voilà! :)

Hi Matadem, what are you using for the .obj import back into MOI?
If it's Max Smirnov's _ImportObj script, that resizes the import by default.
To stop that add a parameter "exact" to the command in your keyboard shortcut.
So set up the shortcut like this:
_ImportObj exact

I have created a cube 10x10x10cm
I have exported as obj and imported in back with both Max import obj and create subD and both are imported just fine. right size.
weird but it works ...so now I have to look at Nvil3d import settings...
almost there..
As I tried other shapes came up with some weird measurements(50cm come in at 14.7cm)....used the import exact...came in at 100x smaller..
so I upped the export 100x in Nvil3d and it seems to open in Moi good.
Tnx!
