Hi Andras, there is a bug in the latest beta with a new option for exporting "analytic entities", like spheres for example.

There is a way to turn off this option for export, to do that shut down MoI and edit the moi.ini file in a text editor like notepad. You can find moi.ini here (on XP, Vista is slightly different, let me know if you are on Vista):
C:\Documents and Settings\ [your login name] \Application Data\Moi\moi.ini

Find the section labeled [NURBS Export], and there should be a setting there:

[NURBS Export]
WriteAnalytics=y

Edit that to say =n instead, and then I think your export will work properly after that, please let me know if it doesn't. Just make sure to close MoI first before editing the moi.ini file, since MoI will also write to it when it closes down.

For the next beta this bug has been fixed and also I've turned off writing analytic entities by default, and there are also going to now be 2 settings, one for surfaces and one for curves.

OK thanks Michael it is working properly

What are Anylitics? (Short version OK)

Hi Burr - "Analytic entities" means using writing objects using special object types, like Circle, Line, Sphere, rather than writing as a generic NURBS curve or NURBS surface object type (NURBS curves or surfaces can still have the shape of an exact circle or sphere though).
