CurveMeshIntersection

Calculates the intersection of a curve object and a mesh object.

Syntax

Rhino.CurveMeshIntersection (strCurve, strMesh [, blnReturnFaces])

Parameters

strCurve	Required. String. The identifier of the curve to intersect.
strMesh	Required. String. The identifier of the mesh to intersect.
blnReturnFaces	Optional. Boolean. Return both intersection points and face indices. If omitted or False, then just the intersection points are returned.

Returns

Array

If blnReturnFaces is either omitted or False, then an array intersection points, if successful.

Array

If blnReturnFaces is True, then a one-dimensional array containing information about each intersection if successful. Each array element is a one-dimensional array that contains the following two elements:

Element	Type	Description
0	Array	The 3-D intersection point.
1	Number	The mesh face index on which the intersection point lies.

Null

If not successful, or on error.

Example

Const rhCurve = 4

Const rhMesh = 32

Dim strCurve, strMesh, arrCMX, arrEv

strCurve = Rhino.GetObject("Select curve to intersect", rhCurve)

If Not IsNull(strCurve) Then

strMesh = Rhino.GetObject("Select mesh to intersect", rhMesh)

If Not IsNull(strMesh) Then

arrCMX = Rhino.CurveMeshIntersection(strCurve, strMesh, True)

If IsArray(arrCMX) Then

For Each arrEv In arrCMX

Rhino.Print Rhino.Pt2Str(arrEv(0)) & ", Face index = " & CStr(arrEv(1))

Rhino.AddPoint arrEv(0)

End If
