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:
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
- 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.
- An Arc parameters section (introduced in version 0.22) is added at the top of the Sketcher Dialog.
- Optionally change the command Mode:
- Mode
Center
:- Pick the center of the arc. Or with Pos-OVP: enter the X and Y coordinate to place the center.
- 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.
- 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- Pick the start and end points of the arc. Or with Pos-OVP: enter X and Y coordinates to place the points.
- Pick another point to define the radius.
- Mode
- The arc is created.
