Check your mouse. It's possible that the electronics died inside while importing drawing just to confuse you.
If it's alive and well close solidworks and reopen.
If reopening solidworks doesn't solve your problem reboot your computer.
Had a similar problem here this morning.
A MS-brand wireless mouse had arbitrarily decided that pressing the wheel was tied to "Flip" (expose all running programs) instead of "middle-click".
The fix was to set an app-specific behaviour of "middle-click" for SW, in the mouse's dialog box under "Devices & Printers" (Not "mouse" under Control Panel!).
Some months ago, my cheap Logitech M185 mouse stopped being able to rotate the view of objects in SolidWorks with the wheel button. Panning in my BricsCAD stopped working as well. I had an identical mouse on my laptop, so I swapped mice, but the problem was still there. Testing the pan function in BricsCAD on the laptop, I found that it also stopped working.
So, at least in my case, it was not the mouse itself. But, rather, apparently some Windows update had broken this function on the . I tried re-installing the drivers, uninstalling the drivers, installing the drivers again, and trying to reconfigure the functions set for the middle mouse button. I gave up, and purchased a cheap Microsoft mouse, which solved the problem.

About once a year I face this issue with my mouse(mice?). The center wheel stops working, we use M-705 mice for convenience everyone likes the contour to the hand and they work pretty well. Back to the topic on hand it is probably coincidence that it happened the way you described. If available grab a mouse from another workstation and try it out on your computer. If it performs the way you expect it to, your mouse wheel has died and time to get a new one. If it doesn't then you have an issue with your computer/ software.
Either way good luck.
No idea - without some pictures or files - drawing files cannot be rotated using the mouse wheel, only the solid model..
