Reset and freeze transformations

- [Instructor] When we organize objects by moving, rotating, and scaling them, we will basically change the values of where those objects are in space. Now there are many times when we'll want to have kind of a home, or a default position for an object. And so for that, we can use what's called, reset and freeze transformations. So here I have two objects in my scene. I have a TV set, and a TV stand.

And let's say I wanted to put that TV set on top of that TV stand. So, I'm going to go ahead and move the stand, kind of in towards the center of the room. And then I'm going to lift up this TV set. And maybe position it so that it's on the TV stand. Now by doing this, I've actually changed the values of its attributes for x, y, and z. And I've done the same for the TV stand.

Now if this is where I really want these objects to be, I can basically reset those to zero, by using what's called freeze transformations. So we have in our modify panel, a "Freeze Transformations" command. And when we do this, notice what happens in the channel box over here. All of the values go to zeroes. So translation and rotation go to zero. And scale goes to one.

So we have the same thing here. We have our TV set. And so let's say we wanted this to be our default position. Well then all we have to do is do Modify, "Freeze Transformations". So now we've got these nice defaults, and everything is at zero. So we know this is where these things are supposed to be. Now if I were to move it, and rotate it around, and change it around, I can always get back to that default position just by highlighting all of these, and typing in zero.

And that brings it to zero. Now another way to do this, is to use what's called reset transformations. Now this does basically the zeroing out, and a little bit more. So if I do Modify, "Reset Transformations". Again, it zeroes everything out, but it does one more thing. It moves the pivot of the object to the origin. Now you may, or may not want this to happen.

But if you don't, then you can always do something like a center pivot to reset it. So if you want to lock down the positions of objects in the scene, you can use freeze transformations. And then reset transformations allows you to put an object back to its original location, and also reset the pivot.
