Arc of ellipse

Arc of parabola

Sketcher

Description

The Sketcher CreateArcOfHyperbola tool creates an arc of hyperbola.

Arc of hyperbola (white) with internal geometry (dark yellow)

Usage

See also: Drawing aids.

1. There are several ways to invoke the tool:
   • Press the Arc of hyperbola by center, vertex, endpoints button.
   • Select the Sketcher → Sketcher geometries → Create arc of hyperbola option from the menu.
   • Use the keyboard shortcut: G then H.
2. The cursor changes to a cross with the tool icon.
3. Pick the center of the major radius of the arc (labelled 1 in the image above).
4. Pick the vertex of the arc (labelled 2 in the image above), this also defines its major radius.
5. Pick the start point of the arc (labelled 3 or 4 in the image above), this also defines its curvature.
6. Pick the endpoint of the arc (labelled 3 or 4 in the image above).
7. The arc of hyperbola is created, including a set of internal geometry.
8. If the tool runs in continue mode:
   1. Optionally keep creating arcs.
   2. To finish, right-click or press Esc, or start another geometry or constraint creation tool.

Notes

• Elements of the internal geometry can be deleted. They can be recreated at any time with Sketcher RestoreInternalAlignmentGeometry.
