Draft Ellipse/sv

Beskrivning
The Draft Ellipse command creates an ellipse in the current working plane from two points defining a rectangle in which the ellipse will fit.

A Draft Ellipse can be turned into an elliptical arc by setting its and  properties to different values.



Usage
See also: Draft Tray, Draft Snap and Draft Constrain.


 * 1) There are several ways to invoke the command:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) * Use the keyboard shortcut: then.
 * 5) The  task panel opens. See Options for more information.
 * 6) Pick the first point in the 3D view, or type coordinates and press the  button.
 * 7) Pick the second point in the 3D view, or type coordinates and press the  button. This point must not be constrained to the X, Y or Z axis.

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, the coordinates of the second point are relative to the first point, 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.
 * Press or click the  checkbox to toggle filled mode. If filled mode is on, the created ellipse will have  set to  and will have a filled face.
 * Press or click the  checkbox to toggle continue mode. If continue mode is on, the command will restart after finishing, allowing you to continue creating ellipses.
 * Press to switch Draft snapping on or off.
 * Press or the  button to abort the command.

Preferences
See also: Preferences Editor and Draft Preferences.


 * To change the number of decimals used for the input of coordinates:.
 * To change the initial value of filled mode: . Changing the filled mode in a task panel will override this preference for the current FreeCAD session.
 * If the option is checked, the command will create a Part Ellipse instead of a Draft Ellipse.

Properties
See also: Property editor.

A Draft Ellipse object is derived from a Part Part2DObject and inherits all its properties. It also has the following additional properties:

Data

 * : (read-only) specifies the area of the face of the ellipse. The value will be if  if  or the face cannot be created.
 * : specifies the angle of the first point of the ellipse, normally.
 * : specifies the angle of the last point of the ellipse, normally.
 * : specifies the major radius of the ellipse.
 * : specifies if the ellipse makes a face or not. If it is a face is created, otherwise only the perimeter is considered part of the object. This property only works if the shape is a full ellipse.
 * : specifies the minor radius of the ellipse.

View

 * : specifies the Draft Pattern with which to fill the face of the ellipse. This property only works if is  and if  is.
 * : specifies the size of the Draft Pattern.

Scripting
See also: Autogenerated API documentation and FreeCAD Scripting Basics.

To create a Draft Ellipse use the method  of the Draft module. This method replaces the deprecated method.


 * Creates an object with given major  and minor  radius in millimeters.
 * The bigger value will be used for the major radius (X axis) if no other placement is given.
 * If is  the ellipse is created at the origin.
 * If is, the ellipse will make a face, that is, it will appear filled.
