Probably not precision, but more likely an internationalization bug - you must have a locale set in Windows that uses the comma character as the decimal point separator?

That program is probably expecting then that numeric data should use a comma as the decimal separator, but that's not the case in OBJ files - OBJ use the period as the decimal separator for numeric values.

Try switching your Windows locale setting to English, or possibly just set the decimal separator setting to a period (as shown in this post here: http://moi3d.com/forum/index.php?webtag=MOI&msg=4282.5) and then maybe that other program will work.

If that does work, then that's a bug in that program, it's using a locale-specific number parsing method instead of using a method that will always use the period as the decimal separator.

I'm not too surprised, it's hardly different from their regular version which is targeted towards mechanical engineers basically...

I bet your son could learn it if he was introduced to it as part of a class instead of just trying to figure it out directly.
