This is what I would do:
Build my blue print or yank the one from LiveType, but it is only SD. In Motions Content there is a Grid.png image. Put that on a blue color solid or shape.
Next, create a rectangle above the group with the Grid and color solid. Make the rectangle the size of the blue print rolled up. Ad a gradient to give it depth. Animate it from one side of the screen to the other. Add a mask to your group that has the grid and color solid in it. Animate the mask so it reveals the paper as the rectangle moves from one side of the screen to the other. It can look really cool. Hope this helps and best of luck.
