I was trying to view a .PAC file, and when I clicked "preview" on the fitchar under model, it opened the new window, with all the check boxes and everything, but the center plane where it's supposed to show the model is completely gray.
Any idea why? Sorry, this has probably been answered before, but I've been trying to figure it out on my own for a while now, and need to go to bed, so figured I'd post and hope someone could give a quick answer.
Thanks
