* Major and minor axes of ellipses are strict and cannot be swapped by resizing the ellipse. This is a consequence of the solver parametrization used (center (x,y), focus1 (x,y) and minor radius length (b)) and the same strict behavior of OpenCascade. The ellipse must be rotated to swap the axes. |
|||
* Ellipse can function as a circle when its major and minor diameter lines are deleted, and one of the foci is constrained to coincide with the center. But radius constraint won't work on such a circle. |
|||
* Moving the ellipse by edge is the same as moving ellipse's center. |

Descriere
The Sketcher CreateEllipseBy3Points tool creates an ellipse by the endpoints of one of its axes and a point along the ellipse. introduced in version 1.0: This is the same tool as Sketcher CreateEllipseByCenter but with a different initial mode.

- There are several ways to invoke the tool:
- Press the Ellipse by axis endpoints, rim point button.
- Select the Sketcher → Sketcher geometries → Create ellipse by 3 points option from the menu.
- Use the keyboard shortcut: G then 3, then E.
- For further steps see Sketcher CreateEllipseByCenter.
