Well, The LOD Reps aren't configurations either. Like design views, they don't alter the model. For example, they don't affect mass or the BOM. They provide levels of detail for display, export, and memory footprint. They allow engineers to slice up a huge assembly in different ways for working and documenting -- without affecting the design itself. R11 does provide iAssemblies too, which do provide design variations. Just clarifying!

Actually, Inventor has selectively loaded data for years. For example, when you open an assembly, only subcomponent display information is loaded. More design/brep data is loaded as needed by commands. This is invisible to the user (no feathers).
I do remember that being one of the early selling points. Or at least something about dynamic loading and 10,000 part assemblies.
If you have 10 partially loaded subs with 1000 parts each… and activate one of the subs to work on one part… are all 1000 then loaded?
SolidEdge v17 came out with some kind of automatic simplification of detail. Creating an assy part config hiding internal features, boxing up shapes and such. To make a smaller part to load. When I hear LOD, that’s what I think of.
All tricks to make the computer faster than physically possible. I like the sound of the part file being smaller. I just want a fast 800 part assy.
In R11, we have the bounding box simplification in Derived assembly where you can simplify a complex assembly into a bounding box and add other features to it. I understand more needs to be done here but it's a start. Thanks.
In SW, you can create a simplified config of a part to use in an assy. But that is not the same as their Lightweight Components. Is'nt that what you were talking about when you said:
“They have had light weight for years and years.“
I’m not going to look it up, but I thought SW’s LW was relatively new.
