3ds Max Modeling Navigating updated Track Views The vertical dimension is not relevant here, and there’s actually a button here that claims to be able to frame the value extents, but that button only works in the Curve Editor. So here we’ve got horizontal zooming only. Just like the keyboard shortcut, which is ctrl + alt + middle mouse, in the Dope Sheet we can zoom in and out just horizontally, but not vertically, whereas in the Curve Editor we can zoom in and out in both dimensions, and these other buttons down here will also work in the Curve Editor, too. Okay, those are the simple additions to the Dope Sheet. We will see in the next movie that the changes to the Curve Editor are much more substantial, and they also include the changes that we’ve seen here.
