yes , no * , principal_axis

yes - Converts and outputs circle records as GOTO points if the normal to the circle plane is not aligned with the tool axis.

no - Outputs circle records in the NCL file without converting circle records to GOTO points, even if the normal to the circle plane is skewed from the tool axis.

principal_axis - Converts and outputs circle records as GOTO points except when the normal to the circle plane is parallel or perpendicular to the tool axis.
