Alt/LMB deselect no longer works in 2.66a

Hi,

I’m new to the forum.

Just updated to 2.66a from 2.63 and noticed that when using the circle or box selector, Alt/LMB no longer works to deselect.
Is there a fix for this problem since using MMB is too awkward while moving the mouse too.

If not Blender Devs please fix this problem.

Hi :slight_smile:
Have you got “emulate 3 button mouse” enabled in the user preferences–>Input section? That should let you use Alt+Left Click to act as the scroll wheel.

Thanks, that worked,
They should have made it a default setting.

My emulate 3 button mouse is greyed out in my preferences…maybe because I have a three button mouse.

I’d like to know how to deselect using Box Select, didn’t know that was possible.

When I want to deselect with Lasso, I just hold SHIFT with CTRL when I click drag a lasso.

Press and hold middle mouse button to deselect with the box.

i do have a 3 buttons mouse

and to de select i use Shift Ctrl and lasso

did you try this one?

problem i have is the sensitiivty of the Altr-B to see a cross section in Viewport
if i do the box slowly it does not work
i have to do the box fast for it to work!
is that normal ?

thanks

My mouse has 3 buttons too and I was able to select emulate 3 buttons. I don’t know why it would grayed out.
Press the B key for the box selector. You see a large crosshair in your view port. Hold left mouse button and rag the mouse over the area you want to select.
Press C for the circle selector. In 2.49 it was press B twice which I prefer. Use the mouse scroll wheel to control the size of the circle.

I have been using Alt to deselect while using the circle selector or the box selector from the beginning. You have to hold it down. I find it the easiest and fastest. I tried with middle mouse before enabling imulate 3 button mouse, but I found it too awkward and I don’t have precise control of my mouse.

It appears using crtl/shift and drag does not work with umulate 3 button mouse on, or it’s not working for me.

Alt/B only gives me the cross hair of the selection box. Most likely Alt is not doing anything unless I hold it down to deselect since I use imulate 3 button mouse.

sorry but Alt-b has to do cross section of a scene in viewport only

after Alt-B you have to draw a box in viewport and it will show cross section

thanks
