CurveTable
==========

.. py:class:: py3dm.CurveTable

   Python wrapper providing access to objects of type ``ON::curve_object``
   stored in an ``ONX_Model``.

   This class offers a convenient interface for adding, retrieving, counting,
   and iterating over curve objects.

   ``CurveTable`` does not own the underlying data; it operates on the
   associated ``ONX_Model`` instance.


   .. py:method:: __iter__() -> collections.abc.Iterator[LineCurve]


   .. py:method:: __len__() -> int


   .. py:method:: add(start: Point3d, end: Point3d, attributes: None | ObjectAttributes = None) -> uuid.UUID
                  add(line: Line, obj_attr: None | ObjectAttributes = None) -> uuid.UUID
                  add(line: LineCurve, obj_attr: None | ObjectAttributes = None) -> uuid.UUID

      Returns the ``UUID`` of the line in case of successful addition, or
      an empty ``UUID`` otherwise. If the line is in the model, then the
      ``UUID`` is unique for all components in the model and is locked.



   .. py:method:: count() -> int

      Returns the number of objects of type ``ON::curve_object`` in the
      model.



   .. py:method:: get_by_uuid(object_uuid: uuid.UUID) -> LineCurve | None

      Returns the object with the given ``object_uuid`` or ``None`` if
      ``object_uuid`` is not found.
