Much easier to use than Acrobat Reader on a PC – 3D PDF Reader Review

Not sure what all the negative reviews are about. If you follow the instruction you can open models form your DropBox account and choose to open them in this app. I find it much easier to browse through models than in Acrobat on a PC which isn't intelligent enough to update the rotation center to the center of the screen. I am really happy with this app. Keep up the good work!
