Hi Bob, is the model pretty large? If it's too big it might not work to upload it here. Could you please try to zip it and see if that will work? Or also you can e-mail it to me at moi@moi3d.com . If it's really large it might not work through e-mail either, in that case you'd need to upload it to a file sharing service like Dropbox or Microsoft OneDrive and then post a link to it.
