You can use the temporary hide/isolate command on the view control bar. Select the elements in the view and then use the "sunglasses" to hide or isolate the selected elements. This setting can also be "pushed" to the visibility and graphics settings for the view if you wish it ti be premenent.

You can also use Visibility/Graphic (VG) to turn off/on categories, i.e. doors, windows, floors, etc. which can help.

There's really nothing as simple as the isolate layer command, since Revit doesn't use layers. I miss being able to select one thing, isolate that layer, and everything on it is isolated. However, do I miss layers? Not at all! :laugh:

With Renogreen's method, you can easily hide categories. So, if you just want structual foundations, use the "uncheck all" button, then check the one or two categories you want.

With Jeff's method, you have to select each element, which can be a pain. Don't forget you can also select one, then use the select all instances visible in view (right click on an element, it's in the pop up menu). I've even created a keyboard shortcut for it. Then, as he said, use the sunglasses.

2 ways to do it. Only you will be able to tell which way is quicker for your particular view.

Take a look at using Filters also to control visibility.

Once you have a specific view setup with only the elements you wish to display, create a View Template from the view,
so you can come back to it later, or apply it to other views.

Worksets should not really be used for display purposes, but occasionally can be used to quickly turn on/off larger groups of elements
which are on specific worksets. Filters are the preferred method, however.

The "sunglasses" hide/isolate is good for working views, and as mentioned is a temporary method. Hide/Isolate in View is another way while working
in a view to adjust what is hidden or isolated.

Hope this helps.

Depending on how complex your needed selection is will sort of depend on how you accomplish this sort of thing. As others have said, you can select specific categories, select all instances of something, or select things one by one while ctrl-clicking them. You can select the elements you want to show and use the "isolate" command, or select everything else and use "hide". If you use the "sunglasses" to temporarily hide/isolate elements or categories, remember that this doesn't affect printing. Temporarily hidden elements will still print. If the elements you've hidden need to not print, then once you've temporarily hidden the elements, you can go back to the sunglasses and select "apply hide/isolate to view". I think this is what Jeff was implying by "push".
Additionally, you can attempt to setup a view filter. This is more complex and requires something specific that will select the appropriate elements, but once setup, you can apply it to multiple views and quickly apply it or not.
