Declaration

public static ICurve Combine(ICurve crv1, ICurve crv2, double precision)

Parameters

Type	Name	Description
ICurve	crv1
ICurve	crv2
System.Double	precision

Returns

Type	Description
ICurve	the combined curve or null, if not possible

GetCommonPlane(ICurve, ICurve, out Plane)

Determines the common plane of the two curves. If there is a common plane, the Parameter CommonPlane gets the result ant the function returns true. Otherwise the function returns false.

Declaration

public static bool GetCommonPlane(ICurve c1, ICurve c2, out Plane CommonPlane)

Parameters

Type	Name	Description
ICurve	c1	first curve
ICurve	c2	second curve
Plane	CommonPlane	the resulting common plane

Returns

Type	Description
System.Boolean

Declaration

public static bool GetCommonPlane(ICurve[] curves, out Plane CommonPlane)

Parameters

Type	Name	Description
ICurve[]	curves
Plane	CommonPlane

Returns

Type	Description
System.Boolean

GetCommonPlane(GeoPoint, ICurve, out Plane)

Determines the commomn plane of a point and a curve. Returns the common plane in the parameter and true if there is such a plane. Returns false, if the point lies not in the plane. Precision

Declaration

public static bool GetCommonPlane(GeoPoint p, ICurve c2, out Plane CommonPlane)

Parameters

Type	Name	Description
GeoPoint	p	The point
ICurve	c2	The curve
Plane	CommonPlane	The common plane

Returns

Type	Description
System.Boolean	true, if there is a common plane, else false

Intersect(ICurve, ICurve, Boolean)

Returns the parameters of the intersection points of curve1 with curve2. Parameters are with respect to curve1. The two curves must reside in a common plane.

Declaration

public static double[] Intersect(ICurve curve1, ICurve curve2, bool onlyInside)

Parameters

Type	Name	Description
ICurve	curve1	First curve for intersection
ICurve	curve2	Second curve for intersection
System.Boolean	onlyInside	if true, only intersction point that are actually on the curves are returned otherwise also intersection points on the extension of ther curves are returned

Returns

Type	Description
System.Double[]	Parameters for the intersection points

Parameters

Type	Name	Description
ICurve	curve1	First curve
ICurve	curve2	Second curve
System.Double[]	par1	Resulting parameters for the first curve
System.Double[]	par2	Resulting parameters for the second curve
GeoPoint[]	intersection	Three dimensional intersection points

Returns

Type	Description
System.Int32	Number of intersection points
