Point
=====
+
+Point feature creates a new construction point.
+
+Point is a construction object and it can be created in a part or in a partset. To create a point:
+
+#. select in the Main Menu *Construction - > Point* item or
+#. click |point_button.icon| **Point** button in the toolbar
+
+There are 5 algorithms for creation of a Point:
+

+ :height: 24px
+
+**By X,Y,Z** creates a point by three coordinates.
+
+.. figure:: images/point_by_distance_on_edge_32x32.png

+ :height: 24px
+
+**By distance on edge** creates a point on an edge.
+
+.. figure:: images/point_by_projection_32x32.png
+ :align: left
+ :height: 24px
+
+**By projection on edge or plane** creates a point by projecting an existing point on an edge or plane.
+
+.. figure:: images/point_by_intersection_32x32.png
+ :align: left
+ :height: 24px
+
+**By intersection of objects** creates a point by intersection of planes or/ and edges.
+
+.. figure:: images/point_by_geometrical_property_32x32.png
+ :align: left
+ :height: 24px
+
+**By geometrical property of object** creates a point in COG or center of arc or circle.
+
+--------------------------------------------------------------------------------
+
+By X,Y,Z
+--------
+
+.. figure:: images/Point1.png
+ :align: center
+
+ **By X,Y,Z coordinates**
+
+A point is created by X, Y, and Z coordinates.
+
+**TUI Commands**:
+
+.. py:function:: model.addPoint(Part_doc, 50, 50, 50)
+
+ :param part: The current part object.
+ :param real: X value.
+ :param real: Y value.
+ :param real: Z value.
+ :return: Result object.
+
+Result
+""""""
+
+The Result of the operation will be a construction point:
+
+.. figure:: images/CreatePoint1.png
+ :align: center
+
+ **Point by coordinates**
+
+**See Also** a sample TUI Script of :ref:`tui_create_point_xyz` operation.
+
+By distance on edge
+-------------------
+
+.. figure:: images/Point2.png
+ :align: center
+
+ **Along an edge**
+
+To create a point, select an edge in a viewer and define a distance along the edge, where point will be defined. This distance can be defined by an absolute value or by a relative one as a ratio to the edge length. The direction of the edge can be reversed by the corresponding check-box.
+
+**TUI Commands**:
+
+.. py:function:: model.addPoint(Part_doc, model.selection("EDGE", "Box_1_1/Left&Box_1_1/Top"), 0.5, True, False)
+
+ :param part: The current part object.
+ :param object: An edge.
+ :param real: A value.
+ :param boolean: Is by ratio.
+ :param boolean: Is reversed.
+ :return: Result object.
+
+Result
+""""""
+
+The Result of the operation will be a construction point created on edge:

+.. figure:: images/CreatePoint2.png
+ :align: center
+
+ **Point created on edge**
+
+**See Also** a sample TUI Script of :ref:`tui_create_point_edge` operation.
+
+By projection on edge or plane
+------------------------------
+
+To create a point by projection it is necessary to select an existing point or wertex which will be projected and an edge or a plane (planar face) on which it will be projected:
+
+**On an edge:**
+
+.. figure:: images/Point3.png
+ :align: center
+
+ **By projection on an edge**
+
+**On a plane:**
+
+.. figure:: images/Point3-1.png
+ :align: center
+
+ **By projection on a plane**
+
+
+The new point will be created by projection of the selected point on the selected object.
+
+**TUI Commands**:
+
+.. py:function:: model.addPoint(Part_doc, model.selection("VERTEX", "Box_1_1/Front&Box_1_1/Left&Box_1_1/Top"), model.selection("EDGE", "Box_1_1/Right&Box_1_1/Top"))
+
+ :param part: The current part object.
+ :param object: A vertex.
+ :param object: An edge or plane.
+ :return: Result object.
+
+Result
+""""""
+
+The Result of the operation will be a construction point created by projection on a plane or an edge:

+.. figure:: images/CreatePoint3.png
+ :align: center
+
+ **Point created by projection on a plane**
+
+**See Also** a sample TUI Script of :ref:`tui_create_point_projection` operation.
+
+By intersection of objects
+--------------------------
+
+A point can be created by intersection of selected objects:
+
+**Two edges**
+
+.. figure:: images/Point4.png
+ :align: center
+
+ **Intersection of edges**
+
+**Edge and plane**
+
+.. figure:: images/Point4-1.png
+ :align: center
+
+ **Intersection of and edge and a plane**
+
+In this case it is possible to define an offset from a plane along the plane normal for the created point.
+
+**Three planes**
+
+.. figure:: images/Point4-2.png
+ :align: center
+
+ **Intersection of three planes**
+
+The new point will be defined by intersection of the selected objects.
+
+**TUI Commands**:
+
+.. py:function:: model.addPoint(Part_doc, model.selection("EDGE", "Box_1_1/Front&Box_1_1/Top"), model.selection("FACE", "Box_1_1/Left"), 10, False)
+
+ :param part: The current part object.
+ :param object: An edge.
+ :param object: A plane.
+ :param real: Offset.
+ :param boolean: Is offset reversed.
+ :return: Result object.

+The Result of the operation will be a construction point created by intersection of objects:

+ **Point created by intersection of axis**
+
+**See Also** a sample TUI Script of :ref:`tui_create_point_intersection` operation.
+
+By geometrical property of object
+---------------------------------
+
+It is possible to use the following property of selected object:
+
+**A center of gravity**
+
+.. figure:: images/Point5.png
+ :align: center
+
+ **By center of gravity**
+
+**A center of circle or arc**
+
+.. figure:: images/Point5-1.png
+ :align: center
+
+ **By center of a circle**
+
+To create a point, select a desirable object.
+
+**TUI Commands**:
+
+.. py:function:: model.addPoint(Part_1_doc, model.selection("SOLID", "Box_1_1"))
+
+ :param part: The current part object.
+ :param object: Solid.
+ :return: Result object.
+
