Description

The Sketcher Create 3PointCircle tool creates a circle by three points on the circle outline. introduced in version 0.22: Or optionally by its center and a point along the radius.

Usage

See also: Drawing aids.

Pos-OVP = Positional On-View-Parameters. introduced in version 0.22
Dim-OVP = Dimensional On-View-Parameters. introduced in version 0.22

  1. There are several ways to invoke the command:
    • Press the 3 rim points button.
    • Select the Sketcher → Sketcher geometries → Create circle by three points option from the menu.
    • The keyboard shortcut: G then 3, C.
  2. The cursor changes to a white cross with the command icon.
  3. The Circle parameters section (introduced in version 0.22) is added at the top of the Sketcher Dialog.
  4. Optionally press the M key or select from the dropdown list in the parameters section to change the tool Mode:
    • 3 rim points:
      1. Pick three points of the circle outline. Or with Pos-OVP: enter their X and/or Y coordinates.
    • Center: introduced in version 0.22
      1. Pick the center of the circle. Or with Pos-OVP: enter its X and/or Y coordinate.
      2. Pick a point to define the radius. Or with Dim-OVP: enter the radius of the circle.
  5. The geometry is created and applicable Pos-OVP and Dim-OVP based constraints are added (none for 3 rim points).
