Description
The 
Sketcher CreateArc tool creates an arc by its center and its endpoints. introduced in version 0.22: Or optionally by its endpoints and a point along the arc.
Arc created in Center mode with automatically applied constraints defined by entering all On-View-Parameters
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 tool:
- Press the
Center and endpoints button. - Select the Sketcher → Sketcher geometries → Create arc by center option from the menu.
- Right-click in the 3D view and select the Create arc by center option from the context menu.
- Use the keyboard shortcut: G then A.
- Press the
- The cursor changes to a white cross with the current tool mode icon.
- The Arc parameters section (introduced in version 0.22) is added at the top of the Sketcher Dialog.
- Optionally press the M key or select from the dropdown list in the parameters section to change the tool mode:
- Center:
- Pick the center of the arc. Or with Pos-OVP: enter its X and/or Y coordinate.
- Pick the start point of the arc, this also defines the radius. Or with Dim-OVP: enter the radius and/or start angle of the arc. The angle is relative to the X axis of the sketch. No constraint is created for this angle.
- Pick the endpoint of the arc. Or with Dim-OVP: enter the aperture angle of the arc.
3 rim points: introduced in version 0.22
- Pick the start and end points of the arc. Or with Pos-OVP: enter their X and/or Y coordinates.
- Pick another point to define the radius. Or with Pos-OVP: enter its X and/or Y coordinate. No constraints are created for this point.
- The arc is created and applicable Pos-OVP and Dim-OVP based constraints are added.
- If the tool runs in continue mode:
- Optionally keep creating arcs.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool.
