Note: once you select a sub-model using MPD Model Selection, you will be able to look at the steps of that submodel (assuming it has steps). Additionally, if you select a sub-model that itself is made up of further sub-sub-models, you will have to select those sub-sub-models from the MPD Model Selection list to see their steps.
Also, if the main model in the MPD has steps of its own (and many probably do), they will show up when the MPD is initially loaded into LDView. (In other words, LDView supports steps in the top-level model of an MPD, it just doesn't show steps from sub-models in an MPD until you open the sub-model.)
