The Mille Delices Dark Library by Lady Littlefox is a figure that has bodyparts which are walls, floor, a bookcase, a chair, etc. I can move the body parts around, but I haven't figured out how to turn them into props so I can just load the parts that I want. I am sure I've forgotten something obvious. Can anyone point me to the solution?

If these parts have separate materials you can use the grouping tool in Poser, select the materials you want and spawn new props. I'm not at my home PC so I can't get a screenshot of what I mean. I'll be back later today if no one else has give you a better answer by then. :)

Poser's grouping tool can probably do what you want. That's the button that looks like a square with a dot in the center. Select one of the body parts then open the Grouping tool. Everything will turn black except whatever is selected. On the group tool there's a button [Create Prop] that will create a prop from whatever's highlighted red. The spawn props button will create a prop from every group in the selected object. That might be handy if you imported the original OBJ geometry file from the set. Then you could spawn all the props at once.

Anyway, once you've spawned whatever prop you needed from the original just save that prop to your library and you can reuse it whenever you want to.

Kalypso and nerd, thank you! It appears to have worked easily and perfectly. Now I want to go through my collection and divide all my figures.
