Draft Arc 3Points/pl

Description
The Draft Arc 3Points command creates a circular arc in the current working plane from three points that define its circumference. The center and radius are calculated from these points.

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

 * 6) Pick the second point in the 3D view, or type coordinates and press the  button.
 * 7) Pick the third point in the 3D view, or type coordinates and press the  button.

Options
The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts.


 * To manually enter coordinates enter the X, Y and Z component, and press after each. Or you can press the  button when you have the desired values. It is advisable to move the pointer out of the 3D view before entering coordinates.
 * Press or click the  checkbox to toggle relative mode. If relative mode is on, coordinates are relative to the last point, if available, else they are relative to the coordinate system origin.
 * Press or click the  checkbox to toggle global mode. If global mode is on, coordinates are relative to the global coordinate system, else they are relative to the working plane coordinate system.

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.
