How to activate OSNAP when adding an elevation point to a feature line

Civil 3D may automatically change OSNAP settings when working with certain objects like feature lines. This can disrupt user preferences and cause workflow issues. You can, however, invoke OSNAP when needed in these situations. The following procedure details how to make an individual OSNAP call.

1. When a command such as InsertElevPoint is active, hold Shift + right-click to open the contextual menu.
2. From the menu, select your desired snap point.

The chosen snap applies only for the next point. Your default OSNAP settings will persist for future object snaps.
