Returns the vertices of the polyline curves generated by contouring a surface or polysurface object.
Rhino.SurfaceContourPoints (strObject, arrStartPoint, arrEndPoint [, dblInterval [, dblAngle]])
|
strObject |
Required. String. The identifier of a mesh object. |
|
arrStartPoint |
Required. Array. The 3D starting point of a center line. |
|
arrEndPoint |
Required. Array. The 3D ending point of a center line. |
|
dblInterval |
Optional. Number. The distance between contour curves. If omitted, the interval will be equal to the diagonal distance of the object's bounding box divided by 50. |
|
dblAngle |
Optional. Number. The maximum angle in degrees between unit tangents at adjacent vertices. If omitted, the maximum angle will be set to 5.0 degrees. |
|
Array |
An array of 3D point arrays, one for each contour, if successful. |
|
Null |
If not successful, or on error. |
