The selection of the curves can form a closed succession.
Remember that the selection can mix 2D, 3D sketch entities and 3D edges as long as they are contiguous.
At the time when the selection buckles on the first entity, a message invites the user to select a point (located on the curves) in order to define the first point to be created.
The points being able to be selected are:
- 2D sketch points.
- 3D sketch points.
- Summit 3D.
- Points of ends of entity 2D or 3D.
