Hi Tom the "Snap Radius" is how close the mouse pointer needs to be on the screen to a snap point for it to engage.

So if you put for example 50 in there you would need to have your mouse 50 pixels away from a snap point for it to use that snap.

If you want snaps to engage more easily then you can put a larger value in there and if you want them to only engage when you are quite close to them you would put in a smaller value.


re:
> - I would like MOI to display the points in smaller size ? How to ?

The point display is one of the few remaining areas that is drawn from a bitmap instead of procedurally. So there isn't any setting to modify for this but if you modify the bitmap images to make the images smaller that would work.

There are 4 images that you'd need to modify, they are all in the UI subfolder:
Point.png
Point_selected.png
Point_transitionfromselected.png
Point_transitiontoselected.png


- Is there a shortcut to open the window "3d view angles" directlly ?

Yup, you can use this:

script: /* Show 3D view angles dialog */ moi.ui.createDialog( 'moi://ui/ViewAngleDialog.htm' );
