## Description

The Sketcher CreateArc tool creates an arc by its center and its endpoints. introduced in version 1.0: 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

Pos-OVP = Positional On-View-Parameters. introduced in version 1.0
Dim-OVP = Dimensional On-View-Parameters. introduced in version 1.0

1. There are several ways to invoke the tool:
• Press the 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.
2. The cursor changes to a cross with the current tool mode icon.
3. The Arc parameters section (introduced in version 1.0) 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:
• 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: introduced in version 1.0
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.
5. The arc is created and applicable Pos-OVP and Dim-OVP based constraints are added.
6. If the tool runs in continue mode:
1. Optionally keep creating arcs.
2. To finish, right-click or press Esc, or start another geometry or constraint creation tool.
