## Selection points or summits

In the '' modeSelection points or summits'', it is possible to use the following filters:

- Summit of the geometries 3D and entity of 2D sketch and 3D.
- 3D or 2D sketch point, circle center point.
- Point of reference.
- Centre of mass.
- Center of circle of 2D sketch or 3D and geometry 3D.
- Center of arc of a circle of 2D sketch or 3D and geometry 3D.
- Center of ellipse of 2D sketch or 3D and geometry 3D.
- Center of arc of ellipses of 2D sketch or 3D and geometry 3D.
- Intersection of the 2 tangents of an arc of 2D sketch or 3D and geometry 3D, this filter cannot thus be combined with the following filters.

- Center of arc of a circle of 2D sketch or 3D and geometry 3D
- Center of arc of ellipses of 2D sketch or 3D and geometry 3D

- To disable all the filters.
- To activate all the filters.

Example of selections:

Selection of a point of center of circle

This selection contains coordinates X, Y, Z of the selected point.

Selection of a center of circle

This selection contains coordinates X, Y, Z of the point of center of the circle as well as information of ray or diameter (See Options of extraction).

By default, the annotation points on the circle, it is possible to point on the center of the circle by checking the option before making the selection.

Selection of an arc of a circle with the filter of intersection of the tangents

This selection contains coordinates X, Y, Z of the point of intersection of the tangents of an arc of a circle.

If the optionis checked, the intersection of the tangents is thus outlined, and the annotation points on the point of intersection.
