OffsetCurveGenerator

Only 2D linear features are supported as input. Self intersecting lines are not supported, and may produce unpredictable results. Other types of geometry will result in undefined behavior.

Each point in the output curve will be the specified offset, measured in ground units, away from the input linear geometry. The output ports Left and Right will produce offset curves on either side of the linear geometry.

This parameter, measures in ground units, specifies the distance by which the output curve is offset from the input curve.

As the diagrams below illustrate, the corner styles of the offset curves can be Round (default), Bevel (chopped), or Miter (pointed). If Miter is used, a limit must be specified using the Miter Limit parameter. If a corner is too pointed for the miter limit, the corner will instead be bevelled.

This parameter, measured in degrees, controls the smoothness of the stroked arcs in the output offset curve. As this parameter decreases in value, the smoothness of the arc connectors increases. The specified value must be between 0 and 90 degrees.

This parameter controls how pointed a buffered corner can be before it is bevelled. It is the highest value that the ratio of corner distance to offset is allowed to have before truncation occurs. A higher number allows for more extreme corner angles.
