The only thing that 'Smart Lightweight Views' and 'Product Outlines' have in common is that they are both based on using faceted representations. However, 'Smart Lightweight Views' is a Drafting only feature while 'Product Outlines' are used as a sort of spatial 'placeholder' which allows you see the context in which a loaded Component(s) exists in an Assembly even if the rest of the Components of that Assembly are not loaded in the current session.
As for 'Smart Lightweight Views' and the older 'Facet' Drawing views, which we've supported for some time, while the idea is that 'Smart Lightweight Views' can and could eventually make the older 'Facet' views all but obsolete, there are still some significant differences. To start with, the absolute 'lightest weight' (using the least amount of memory and having the fastest update) drawing view that you can create will still be the older style 'Facet' drawing view. However, unlike the new 'Smart Lightweight Views', a 'Facet' view can only be seen with all hidden lines invisible (i.e. no 'dashed' hidden edges), cannot be dimensioned nor have section views created from them. However, they are still useful if all that you're looking for is a simple illustration, such as isometric view placed on a Drawing so that you can show what the part looks like. However, if you want to have the best performance with the least use of memory yet still be able to create associative dimensions, create section and break-out views, show hidden edges as dashed, etc., then the new 'Smart Lightweight Views' is the way to go. Note that you can still use 'Exact' views on Drawing which will still provide the BEST LOOKING rendered views, that is with no jagged or so-called 'facet' effect (i.e. even small circles are smooth) but they are also require the most memory and take the longest time to update when changes are made to the model.
Anyway, I hope that explains a little better the difference between the various 'facet' type representations used in NX and where they are intended to be used and what they offer or not offer in terms of functionality.
