050147: The interpolate vertices only option must be used when the interpolation method is set to nearest.


When using the Interpolate Shape tool with a line or polygon feature class and the Nearest Neighbor interpolation method, only the calculation of z-values at the feature vertices is permitted. The Interpolate vertices only parameter is automatically checked when this method is used. This error is returned if the parameter is unchecked.


Ensure that the Interpolate vertices only parameter remains checked when using the Nearest Neighbor method.
