Pop-up | Set As Snap/Grab Target (Layers window) |
Designate the selected layer as the target layer containing the vertices to which you will snap when selecting data.
In order to snap to existing vertices, you must have a layer designated as the target layer containing the vertices to which you will snap. By default, the currently selected layer is set as the snap/grab target and the drop-down list will read "Use current layer". If a layer is active that is not snappable, the drop-down list is disabled.
When the target layer is changed from the default to a specific layer, the selected layer is remembered until a different target is selected, regardless of the active layer in the Layers window.
Procedure
1. Right-click on a layer in the Layers window.
2. Select the Set As Snap/Grab target command.
The selected layer is now a snap/grab target.
