## Description

The Arc 3Points tool creates a circular arc in the current work plane by entering three points that lie on the circumference; the center and radius are determined from these three points. It uses the Draft Linestyle set on the Draft Tray.

Use the Draft Arc tool to create a circular arc by specifying the center, the radius, and the start and end angles. To draw an elliptical arc use Draft Ellipse. You can also approximate a circular arc by using the Draft BSpline, Draft BezCurve, and Draft CubicBezCurve tools.

Arc defined by three points lying on a circumference

## How to use

1. Press the button, or press A then T keys.
2. Click a first point on the 3D view, or type a coordinate and press the button.
3. Click a second point on the 3D view, or type a coordinate and press the button.
4. Click a third point in the 3D view, or type a coordinate and press the button.
5. The arc will be created after the third point is given.

## Options

• Press X, Y or Z after one point to constrain the following point on the given axis.
• To enter coordinates manually, simply enter the numbers, then press Enter between each X, Y and Z component.
• You can press the button when you have entered the desired values to insert the point.
• Press R or click the checkbox to toggle relative mode. If relative mode is on, the coordinates of the following point are relative to the previous one; if not, they are absolute, taken from the origin `(0, 0, 0)`.
• Hold Shift while drawing to constrain your next point horizontally or vertically in relation to the previous one.
• Press Esc or the Close button to abort the current command.

## Properties

An Arc object shares all properties from a Draft Circle, but some properties only make sense for the circle. See Draft Arc for more information.
