Set Dynamic Snap On/Off
You can use this switch to activate or deactivate the Dynamic Snap mode. When the dynamic snap mode is active, ARC+ displays the colored icons to locate the points that can be snapped, as per the options you have selected (snap at mid point, end point, etc.) When this mode is disabled and one or more snap options are selected, the snap still works but no preview is available. However, you need to ensure that you are using the mouse button that is configured for snap (you can check the mouse configuration in the User preferences dialog box).
