File size and formats

Hi,

I'm very new to MoI and have purchased it mainly to convert CAD data for use in my other 3d apps.

I have a .stp of 1.2gb and it's causing MoI to hang then crash.

Is there a file size limit and if so what is it?

I've also been supplied the object as a 3d PDF file but when I try and open it, the scene is empty and without any 3d data at all.

Does anyone here have experience of using 3d PDF with MoI, who could offer me some assistance?

Thanks in advance.

Simon
