# Is there a way to rotate and pan view while in knife tool and other tools that lock the view ports?

It seems there are many tools, such as the knife tool, that cause the viewports to lock up when you are "in" the tool. By "lock up" I mean that while in the tool I cannot rotate, pan, or zoom the view. This would be super handy and seems like a no-brainer. Thanks for your help! -Ben

• What is the problem to rotate / grab the view while in the Knife tool by pressing MMB / Shift + MMB ? You can also zoom as usual, by scrolling the wheel. – Mr Zak Sep 4 '15 at 21:27
• That's what I mean. I expect I SHOULD be able to do that, but I can't. I say the view locks up and the normal mouse navigation you are describing does not work as long as the tool is active. – Ben Mora Sep 4 '15 at 21:34
• I'm not sure where the problem is, as it works for me pretty well (versions 2.74 and 2.75 ) – Mr Zak Sep 4 '15 at 21:38
• Wait, silly me... I've been using not a regular mouse but a 3D mouse (3Dconnexion) and got so used to it that I forgot I was doing it. I just tested with regular mouse and it IS working as I would expect. So I guess the issue is that this 3D mouse stops manipulating the view while the tool is active. I guess there's not likely a solution for that as it is a third-party issue. – Ben Mora Sep 4 '15 at 21:43
