Description

The Sketcher CreateArcOfEllipse tool creates an arc of ellipse by its center, an endpoint of one of its axes, and two points along the arc.

Usage

See also: Drawing aids.

  1. There are several ways to invoke the tool:
  2. The cursor changes to a white cross with the tool icon.
  3. Pick the center of the arc of ellipse.
  4. Pick an endpoint of one of the axes of the arc, this also defines one of its radii.
  5. Pick the start point of the arc, this also defines the other radius of the arc.
  6. Pick the endpoint of the arc.
  7. The arc of ellipse is created, including a set of internal geometry (major axis, minor axis and two foci).
  8. Optionally deleted one or more elements of this internal geometry. They can be recreated at any time with Sketcher RestoreInternalAlignmentGeometry.

Notes

  • Once created, the major and minor axes of an elliptical arc are strict and cannot be swapped by resizing. This is a consequence of the solver parametrization and the same strict behavior of OpenCASCADE. An elliptical arc must be rotated to swap its axes.
