You can set the snapping priority for layers listed in the Snapping Environment window to determine the order in which snapping will occur. Snapping occurs first to features in the layer at the top of the list, then to each consecutive layer down the list. You can easily change the snapping priority by dragging and reordering the list of layers.
The Snapping Environment window is the main place for you to specify the settings for classic snapping by choosing the layer and the snapping type (vertex, edge, or end).
- Click the 3D Editor menu.
- Click Snapping and click Snapping Window.
The Snapping Environment window appears.
- Click and drag the layer names to arrange them in the order you want snapping to occur.
The snapping priorities you set are effective immediately.
