Description

The Sketcher CreateArc tool draws an arc by picking three points: the center, the start point for the radius, and the end point for the angle.

While this tool is active, the mouse pointer changes to a white cross with a red arc icon:

The center has been selected, dragging to set the radius‎ The center and start angle have been selected, dragging to set end angle‎

Arc with automatically applied constraints as defined by entering on-view-parameters
(leaving only the angle of the start point disregarded)

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 Center and end points button.
    • Select the Sketcher → Sketcher geometries → Create arc by center option from the menu.
    • Right-click in the Sketch view and select the Create arc by center option from the context menu.
    • The keyboard shortcut: G then A.
  2. An Arc parameters section (introduced in version 0.22) is added at the top of the Sketcher Dialog.
  3. Optionally change the command Mode:
    • Mode Center:
      1. Pick the center of the arc. Or with Pos-OVP: enter the X and Y coordinate to place the center.
      2. Pick the start point of the arc, this also defines the radius. Or with Dim-OVP: enter the radius, and the start angle to place the start point.
      3. Pick the end point of the arc. Or with Dim-OVP: enter the aperture angle to place the end point.
    • Mode 3 rim points: introduced in version 0.22
      1. Pick the start and end points of the arc. Or with Pos-OVP: enter X and Y coordinates to place the points.
      2. Pick another point to define the radius.
  4. The arc is created.
