Thanks for the help, I had checked attributes and class set to solid and they are, but those drop-downs in the OIP for the base cabinets are greyed out whether Show Detail is checked or not, and those are all set to class None.
That's the one thing I changed, I always change class none to No Fill. I'm just learning the 3D of VW after 30 years using it mainly as a 2D drafting tool; in that mode having None set to solid is a major annoyance so that is the one thing I always reset if I'm using a VW template.
So I changed None back to Solid and things render as they should!
Still need to understand why almost all the parameters in the OIP for the base cabinet are greyed. I'll leave that for tomorrow.
