AnchoredSnapper

Features that may have CANDIDATE features snapped to them. Arcs are snapped as linear features, and ellipses are snapped as polygonal features.

Features that may be snapped to ANCHOR features. Arcs are snapped as linear features, and ellipses are snapped as polygonal features.

Features whose geometry is changed by the transformer.

Features that leave the transformer without being changed.

If you select Group By attributes, only those features with the same Group By attribute values will be snapped together.

When Snapping Type is End Point Snapping:

• The transformer snaps endpoints of features that enter via the CANDIDATE port to endpoints of features that enter via the ANCHOR port. ANCHOR features are not output.
• Point features can be used as ANCHOR or CANDIDATE features, and CANDIDATE points will be snapped together (or to a linear base feature) as well.
• The transformer will not alter area features.

When Snapping Type is Vertex Snapping:

• The transformer snaps vertices of features that enter via the CANDIDATE port to vertices of features that enter via the ANCHOR port. ANCHOR features are not output.
• Point features can be used as ANCHOR or CANDIDATE features, and CANDIDATE points will be snapped together (or to a linear ANCHOR feature) as well.
• The transformer will alter area features.

Snapping Tolerance specifies the distance, in ground units, that the snapping occurs between features.

This parameter applies only when the end point of a feature is being snapped.

• NEVER: the endpoint of a line is moved when it is snapped and no additional vertex is added.
• ALWAYS: the original end point (start point) of the line becomes the second from the end (start) and a new vertex is added to complete the snap.
• FORWARD_ONLY: a new vertex is added only when doing so creates an angle greater than 90 degrees with the original line segment. In this case, if adding the vertex would cause a less than 90-degree angle, the old end point is still moved.
