Draft Arc 3Points

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



Usage

 * 1) There are several ways to invoke the tool:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) * Use the keyboard shortcut: then.
 * 5) Click the first point in the 3D view, or type coordinates and press the  button.
 * 6) Click the second point in the 3D view, or type coordinates and press the  button.
 * 7) Click the third point in the 3D view, or type coordinates and press the  button.

Options

 * Press, or  after one point to constrain the following point on the given axis.
 * To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component.
 * You can press the button when you have entered the desired values to insert the point.
 * Press 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.
 * Hold while drawing to constrain your next point horizontally or vertically in relation to the previous one.
 * Press or the  button to abort the tool.

Properties
A Draft Arc is in fact a Draft Circle with a that is not the same as its. A Draft Arc therefore has the same properties as a Draft Circle.

To create a Draft Arc by 3 points use the method of the Draft module:


 * Creates an object from the given  list.
 * If a is given, the center of the circular arc will be moved to this place. See Placement for more information.
 * If is, the arc will make a face, that is, it will appear filled.
 * If is given, it is a, that is, a list indicating an object, and a subelement of that object. This is used so that the object appears referenced to this support.
 * For example:.


 * If is given, it is a string defining a type of mapping, for example: ,  , etc. See Part Attachment for more information.
 * If is, the arc created will be a simple Part Feature, not a complex Draft object.
