Description

The Sketcher CreateArcOfParabola tool creates a parabolic arc.

Parabolic arc (white) with internal geometry (dark yellow)

Usage

See also: Drawing aids.

Pos-OVP = Positional On-View-Parameters.
Dim-OVP = Dimensional On-View-Parameters.

introduced in 26.3: OVP support added.

1. There are several ways to invoke the tool:
   • Press the Parabolic Arc button.
   • Select the Sketch → Geometries → Parabolic Arc option from the menu.
   • Use the keyboard shortcut: G then J.
2. The cursor changes to a cross with the tool icon.
3. Pick the focus of the arc (labelled 1 in the image above). Or with Pos-OVP: enter its X- and/or Y-coordinate.
4. Pick the vertex of the arc (labelled 2 in the image above), this also defines its focal distance. Or with Dim-OVP: enter this distance and/or the angle of the axis of the arc. The angle is relative to the X-axis of the sketch.
5. Pick the start point of the arc (labelled 3 or 4 in the image above). Or with Dim-OVP: enter the start parameter of the arc. The parameter is relative to the axis of the arc. No constraint is created for this parameter.
6. Pick the endpoint of the arc (labelled 3 or 4 in the image above). Or with Dim-OVP: enter the end parameter of the arc. The parameter is relative to the start of the arc. No constraint is created for this parameter.
7. The parabolic arc is created, including a set of internal geometry, and applicable Pos-OVP and Dim-OVP based constraints are added.
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.
