using shift to deslect

[jw7018]

Greetings, 

Sometimes it is easier to select too many items and deselect one or three via holding down the shift to deselect.

My issue is sometimes i am able to deselect as many items i wish to in one click and others i must deselect each item individually.

Is there a setting/process how to deselect all you chose with one click or is this a glitch?....as I've had it both ways, with it out my control.

"sometimes" has no fix: is there something else at play perhaps? Like you are using a Window instead of a Crossing Window and not catching all you want to deselect?

Maybe these options?

Could you clarify the difference between a window and a crossing window? thanks

I've added a screen shot of my selected items and of the window I am deselecting with shift command.

Looking at your 3D view, what exactly are you trying to deslect? Your Crossing Window method seems to be selecting everything you've already selected.

that was just a representation of selected items and my selection window........... there were more selected items out of view.

per your video I have been selecting with the proper Implied & Crossing windows. (knew their function....never knew their proper names)

Which brings me back to my original post (sometimes all items will be de-selected with the shift command and  others they have to be selected one at a time.

Dig a little deeper next time it happens, observe what actions you are doing, try to repeat the problem, see what else can be done.

Hi jw7018,

Check your PICKADD and PICKAUTO system variable its will be  2 and 1

Sometime using Autolisp and other Add-Ins has been changed the system variable for the performance of the Add-Ins. May its happening after using any Add-Ins by you.
