ModelsetSectioning(Point3dCollection, Vector3d, Double, Double) Method

Sets the active sectioning for this Model object. The sectioning is capped vertically using the specified top and bottom heights. After specifying the sectioning, it should be enabled with the EnableSectioning property.

Public Overridable Function setSectioning (

virtual bool setSectioning(
        Point3dCollection^ points, 
        Vector3d upVector, 
        double dTop, 
        double dBottom
)

abstract setSectioning : 
        points : Point3dCollection * 
        upVector : Vector3d * 
        dTop : float * 
        dBottom : float -> bool 
override setSectioning : 
        points : Point3dCollection * 
        upVector : Vector3d * 
        dTop : float * 
        dBottom : float -> bool

Parameters

points Point3dCollection: [in] Array of co-planar points specifying a sectioning region.
upVector Vector3d: [in] Vector that specifies the orientation of the plane that contains points.
dTop Double: [in] Specifies the top capping height of the sectioning.
dBottom Double: [in] Specifies the bottom capping height of the sectioning.

Return Value

Boolean
true if the specified sectioning is valid. Returns false if the specified sectioning is invalid or malformed.

Remarks

If the last point of the points array is equal to the first point of this array, the sectioning region is closed. The upVector is used to specify the clipped and unclipped sides of the sectioning. The unclipped side is determined by the direction of the cross product of the first line segment defined by the point array and the upVector.
