## FreeFormGeometryType

Specify the spline type in the output IGES file to convert free form curves and free form surfaces to.
Please note that this value will be used for analytic curves as well when “WriteCircle=0”, “WriteEllipse=0”, and/or “WriteLine=0”.

  - 3: Use type 108 (form 0 or 1)

## WriteLine

Specify whether to convert lines as Line (Type 110) in the output IGES file.
Please note that, when this is set to “0”, lines will be converted as Rational B-Spline Curve entity (Type 126) when “FreeFormGeometry=0”, and as Parametric Spline Curve entity (Type 112) when “FreeFormGeometry=1”.

- Values
  - 0: Don’t convert as Circular Arc (Type 100)
  - 1: Convert as Circular Arc (Type 100)

## WriteEllipse

Specify whether to convert ellipses as Conic Arc (Type 104) in the output IGES file.
Please note that, when this is set to “0”, ellipses will be converted as Rational B-Spline Curve entity (Type 126) when “FreeFormGeometry=0”, and as Parametric Spline Curve entity (Type 112) when “FreeFormGeometry=1”.

- Default Value: 1
- Values
  - 0: Don’t convert as Conic Arc (Type 104)
  - 1: Convert as Conic Arc (Type 104)
