Adobe Acrobat Reader DC has a 3d viewer..mine come with my computer.works pretty well and has some nice features..do believe it's free to download online..
Thanks. I did know that, just wanted to know about TurboPDF.
I just dumped my adobe creative cloud subscription that I have had for years. Just got tired of giving them $75.00CAD every month. Now, after all that money, I've got nothing to show for it except a hate for them. I am finding alternate software to replace the programs I used. Sorry for the mini-rant. :-)
