I am using Visualize for the first time to make an assembly video and everything was going well. Then all of a sudden the mouse scroll wheel stopped working. I don't recall doing anything, I have restarted and tried other files but I can no longer zoom or rotate with the scroll wheel. It works in every other program including Solidworks 2018, and I can even pan by holding Alt+scroll wheel. I just can't do the normal functions and it slows me way down having to select zoom and scroll from the panel. Any ideas?
Perhaps try toggling the setting for Viewport Navigation. Even if it's set to SOLIDWORKS CAD (where middle mouse button controls rotation) try setting to SOLIDWORKS Visualize, and then back to SOLIDWORKS CAD...
