How to Fix Issues with the Middle Button on Your CAD Mouse

BIM Software Tip: How to Fix the CAD Mouse Middle Button Issue

Typically, the CAD scroll wheel allows you to zoom in and out. It also supports panning by holding down the middle mouse button.

However, sometimes when you hold down the scroll wheel button, instead of panning, a menu appears, which can be quite frustrating.

To resolve this, adjust the system variable mbuttonpan, which is set to 1 by default.

This setting enables actions defined by menu (.mnu) files, allowing translation (panning) when holding down and dragging with a button or the scroll wheel.

If you notice that the model and layout tabs are missing from the command line, try this solution: enter -op (Options), go to Display, and ensure that both the Display Layout and Model options are checked.
