Can't drag drawing view boundary

I have a component with a large radius, where the centre is off the page. With previous versions of SW, it was easiest to manually draw a centre mark, then drag the drawing view boundary out to cover the mark so I could add some dimensions, then add the correct value manually.

Now in SW2010 I can't drag the view boundary, and it won't let me create a dimension to a line that is outside the boundary. How do I do this? Why can I not drag the boundary any more?
