Though we haven't released many add-on catalogs for the Home Designer Product line recently, we have done some updating (maybe about 30% so far?) to the Core Catalogs.
From the Library menu, select "Update Library Catalog" to get the latest objects. You should notice that many objects, specifically in the Appliances, Lighting, and Furniture areas, have been updated to have higher quality and modernized 3D geometry.
Because these objects are stored in the Library only, you will need to replace items in your designs with the new variations... objects in your existing designs will not update automatically.
We have more updates to the core catalogs and the bonus catalogs you have access to from the 3D Library planned. Hopefully these changes will help to make your scenes more interesting and relevant!
