Description

Constructs a geodetic line connecting the specified points. The esriCurveDensifyByLength and esriCurveDensifyByDeviation densification methods can be specified. If the from point has a spatial reference (PCS or GCS) associated with it, then that spatial reference will be assigned to the polycurve being constructed. Otherwise, if the polycurve already has a spatial reference, that one will be used. See the above section on common behavior for additional information on this method. This method is not implemented for polygons (E_NOTIMPL is returned).

Errors Returned

Returns E_NOTIMPL if used with polygons.

Remarks

Length of output line will always be less than one hemisphere.
