It should be possible to create a 2D drawing from a 3D lightweight model or assembly in Creo Elements/Direct Modeling. this would provide a quick way to load a very large assembly, lightweight, and then create a 2d drawing of it. sure you can use mangage parts to reduce the level of detail in your drawing, but you still need to load the entire model. Better would be if you could load the lightweight, and produce a low level detail 2d drawing of it.
