'Swipe' as in dragging your finger across the screen of a touch-screen mobile device supporting BIMx (e.g., iPhone, iPad).
When you first go into your project in the BIMx app on your mobile device, it shows your published drawing set. Try to open the single sheet you recognize containing the first part of your drawing list. When it is open on the screen, drag the image to the left and it will (hopefully) show the second sheet of your multi-sheet drawing list.
