Description

The Sketcher CreateArcOfParabola tool creates an arc of parabola.

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 focus point of the arc (labelled 1 in the image above).
  4. Pick the tip of the arc (labelled 2 in the image above).
  5. Move the cursor away from the previous points and pick the start point of the arc (labelled 3 in the image above), this also defines its curvature.
  6. Pick the endpoint of the arc (labelled 4 in the image above).
  7. The arc of parabola is created, including a set of internal geometry.
  8. Optionally deleted one or more elements of this internal geometry. They can be recreated at any time with Sketcher RestoreInternalAlignmentGeometry.
