- [Instructor] When you're working on a scene
with many objects and you just want to focus on one thing,
you can either isolate the object,
which will hide everything else,
or you can lock the current selection
so that you can't select anything else.
Let's look at isolate first.
All you have to do is just select something
in this case, maybe select this sofa, which is a group.
And then and at the bottom of the interface
is a button that looks like a little cyan square
with a bracket around it.
And that is Isolate Selection.
Click on that and now everything else is hidden
in the scene.
And additionally, the active viewport zooms in to
enclose the extents of the current selection.
All right, so we can turn that back off again.
We can deisolate everything by clicking on
that button again.
If you want to use keyboard shortcuts
then it's a little bit complicated with Isolate Selection.
The isolate command has a keyboard shortcut or hot key
which is Alt + Q.
However, if you try to unisolate using Alt + Q,
it doesn't work.
So when you want to unisolate using a hot key,
unfortunately there's a separate hot key for that
which is Control + Alt + Q and that toggles
this state of isolation.
You can use Control + Alt + Q to enter isolation,
and to exit isolation, but the standard keyboard shortcut
Alt + Q will only enable isolation.
All right, now let's talk about locking.
That's kind of a similar concept.
You can select any object or group such as this table,
and you can lock the selection.
There's little padlock down here.
And that will turn yellow.
Not only can you not select anything else now,
but you cannot deselect the current selection.
So we've locked the selection completely.
All right, we can turn that back off again,
select some other object.
There is a keyboard shortcut for that,
which is Control + Shift + N.
And that will turn on the padlock icon.
And now I can't select anything else,
and I can't deselect the current selection.
This one does toggle the state using that hot key.
So you can hit Control + Shift + N again,
and that'll turn lock selection off.
There's another way to do it too,
which is to use the spacebar.
Tap the spacebar, you get a little popup menu,
and you can do stuff here such as lock the selection.
So click on that.
It's the same as clicking on this little padlock.
Press that spacebar again,
you can go back to that menu and disable lock selection.
Okay, so that's how to isolate and lock selections.
