Some confusion exists between the different visibility control mechanisms we have in Revit.
And it's no wonder.. There are so many possible combinations that it takes real skill to keep them all organized.
Here are the main ones that are giving people issues.. there are others to help complicate things, but we'll start with these:
- You can select an individual object and with a right click - select Graphic Override, and make it look any way you want.
- You can also select any individual object and with a right click - Hide it or the entire category in which it belongs.
- Categories give you the ability to make an entire category look any way you want (and the ability to turn an entire category on/off).
- Worksets gives you the ability to group items (even from different categories) and turn them on/off.
- Filters give you the ability to make your worksets (and other items) look any way you want them. (All grey, All dashed and light blue, etc.).
- Phases give you the ability to tell items when they were created and when (if at all) they will be demolished.
- Phase Filters give you the ability to make a graphic distinction between new and existing phases (Grey Existing, Dark New, Existing Off, etc.)
Now that should make things as clear as mud.
