Checks whether the surface is planar. If the surface is planar, also receives the plane information and normal.

Syntax

public bool IsPlanar(
        out Point3d ptOnSurface,
        out Vector3d normal
)

Public Function IsPlanar ( 
        <OutAttribute> ByRef ptOnSurface As Point3d,
        <OutAttribute> ByRef normal As Vector3d
) As Boolean

public:
bool IsPlanar(
        [OutAttribute] Point3d% ptOnSurface, 
        [OutAttribute] Vector3d% normal
)

member IsPlanar : 
        ptOnSurface : Point3d byref * 
        normal : Vector3d byref -> bool

ptOnSurface Point3d: [out] Receives the point on the surface (if the surface is planar).
normal Vector3d: [out] Receives the plane normal (if the surface is planar).

Boolean
true if this surface is planar, false otherwise.

Remarks

If the surface doesn't contain any NURBS information, the method throws the eFail exception.
