Returns the vertices of the polyline curves generated by contouring a mesh object.
rhinoscript.mesh.MeshContourPoints( mesh_id, start_point, end_point, interval=None, remove_coincident_points=False)
mesh_id |
Required.字符串或 Guid。The identifier of a mesh object. |
start_point |
Required.List of 3 numbers of Point3d.The 3-D starting point of a center line. |
end_point |
Required.List of 3 numbers or Point3d.The 3-D ending point of a center line. |
interval |
可选参数。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. |
remove_coincident_points |
可选参数。Boolean.Remove coincident points.If True, and the polyline curves from which the contour point are taken are closed, then duplicate starting and ending points of the polyline curve will not be returned.The default is to return duplicate starting and ending points (False). |
List |
A list of 3-D point lists, one for each contour, if successful. |
None |
如果执行不成功或出错，返回空值。 |
