when we want to select varsites horizantally or vertically by pressing "Alt" (selected one varsites) but this is not working in my side so is there any settings or anything that I have to enable or disable. please let me know
Hi MMjoshi8794 ,
If you are on Windows and Select with LMB and have Emulate 3-Button Mouse enabled, you can't use ALT+Select, but you can double-click on an Edge, to Select an Edge Loop.
(On Mac or Linux, you can set the Modifier Key to the OS- Key in your Preferences:
.)
It is also possible, that your OS uses the ALT combination for something else and overrides Blender's use. Then you'll have to either change your OS shortcut, or the Blender shortcut:
It is also possible, that you're doing something wrong, or something's not right with your model; I highly recommend to try this on a default Cube. Just add a Loop Cut with CTRL+R and then try to Select that.
