XformWorldToCPlane

Transforms a point from world coordinates to construction plane coordinates.

Rhino.XformWorldToCPlane (arrPoint, arrPlane)

arrPoint

Required. Array. A 3-D point in world coordinates.

arrPlane

Required. Array. The construction plane. The elements of a plane array are as follows:

Element	Description
0	Required. The construction plane's origin (3-D point).
1	Required. The construction plane's X axis direction (3-D vector).
2	Required. The construction plane's Y axis direction (3-D vector).
3	Optional. The construction plane's Z axis direction (3-D vector).

Array	A 3-D point in construction plane coordinates if successful.
Null	If not successful, or on error.

Dim arrPlanePt, arrPlane, arrPoint

arrPoint = Array(0.0, 0.0, 0.0)

arrPlane = Rhino.ViewCPlane

arrPlanePt = Rhino.XformWorldToCPlane(arrPoint, arrPlane)

If IsArray(arrPlanePt) Then

Rhino.Print "CPlane point: " & Rhino.Pt2Str(arrPlanePt, 3)

End If
