***READ ME - 3D PDF Viewing*** The 3D PDF allows the user to pan/tilt/scale the model. To view 3D PDFs: - Open with Adobe instead of with a default web browser. - When a blank screen appears, click the yellow pop-up banner in the upper left of the PDF viewer to allow for 3D display/animation. - It may take several tries to click the options tab in the banner and allow the display of 3D PDF images. - If the 3D PDF image still doesn't work, go into Adobe Preferences Edit > Preferences > 3D & Multimedia > Enable playing of 3D content (check the box).
