This registry entry determines whether or not the Snap list is visible for an Auto Circle in the Measurement Properties area of the Auto Feature dialog box.
Entry Name: EnableCircleDccSnap
Entry Type: Boolean value. If set to True, it displays the Snap list inside the dialog box. If set to False, it is hidden in the dialog box.
Even if the list is hidden in the dialog box, it does not always mean that the SNAP field is hidden in the Edit window. The Edit window SNAP field is only hidden if the field is set to NO and this registry entry is then set to False. If the SNAP command in the Edit window is set to YES, the field always remains visible in the Edit window.
