how to reset a view pane in cinema 4d

I am new to cinema 4d and I built a model which is easily viewable in my right, top, and front viewports, but in perspective view I can't see anything, and I can't开发者_如何学JAVA figure out how to reset or recenter the view. Anybody know how to do this?

This might be useful too: You can press "o" to center the selected Object in the current viewport

Besides the undo command, there is also "Frame Default" command in the edit menu of the view panel.

Well, I didn't quite figure out a "reset" button, but what I did realize is that cinema4d has two styles of undo - one for actions undertaken within the program, and one for the views themselves, so I was able to successfully undo using the viewpane undo mode.
