Description
The Sketcher CreateArc tool creates an arc by its center and its endpoints. (v1.0) : Or optionally by its endpoints and a point along the arc.

Usage
See also: Drawing aids.
Pos-OVP = Positional On-View-Parameters. (v1.0) Dim-OVP = Dimensional On-View-Parameters. (v1.0)
- 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 cross with the current tool mode icon.
- The Arc parameters section ((v1.0) ) 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**: 1. Pick the center of the arc. Or with Pos-OVP: enter its X and/or Y coordinate. 2. 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. 3. Pick the endpoint of the arc. Or with Dim-OVP: enter the aperture angle of the arc.
-
**3 rim points**: (v1.0) 1. Pick the start and end points of the arc. Or with Pos-OVP: enter their X and/or Y coordinates. 2. 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.
