You´d create a bogus export, flood the support hotline with requests
and would get the feeling XSI is unreliable.
Unless of course you read the manual first, in which case you'd be familiar with XSI's terminology and know better than to e-mail support about it...
The term "model" in XSI describes something very specific (a type of object). So, "export model" does exactly what it says it does. It exports an XSI model just not any old 3d model. The terminology can be confusing...
You know that if you have something selected and hit the "model>new model" button, it automatically sticks whatever you have selected under it? It might save you a couple of clicks... :)
