it's a hassle to fix unorganized models, good thing there's 5d+ 

The "Preview Paper" needs you hover the mouse over the button then press Ctrl key first to change the button's state, similar to "Rotate View 90" with Shift key. There's a tooltip appeared to guide you when hovering over the button.

Please make more of these videos. This seems like a great BIM plugin.

If you want to change "Definition name" of a group, you can use 5D+ Auto Info also. The floor label will display name of floor type, (like wall label for wall type, ceiling label for ceiling type) not for naming a room or a space/zone. Material label for materials you painted on faces, it's not related to material tags.

If you installed 5D+ Auto Info. After using Auto Select objects, they will be automatically sent to 5D+ Auto Info to display as a schedule table.

Thank you
