Draft BezCurve/pl

Description
The Draft BezCurve command creates a Bézier curve from several points.

The command creates a single Bézier curve with a that is. It can be transformed into a piecewise Bézier curve by reducing this property.

The Draft BezCurve and the Draft CubicBezCurve commands use to define the position and curvature of the spline. The Draft BSpline command, on the other hand, specifies the through which the curve will pass.



Usage

 * 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 additional points in the 3D view, or type coordinates and press the  button.
 * 8) Press  or the  button to finish the command.

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.
 * Press or click the  checkbox to toggle filled mode. If filled mode is on, the created curve will have  set to  and will have a filled face, provided it is closed and does not self-intersect. Note that a self-intersecting curve with a face will not display properly, for such a curve  must be set to.
 * Press or click the  checkbox to toggle continue mode. If continue mode is on, the command will restart after using  or, or after creating a closed curve by snapping to the first point of the curve, allowing you to continue creating curves.
 * Press or the  button to undo the last point.
 * Press or the  button to finish the command and leave the curve open.
 * Press or the  button to finish the command and close the curve. A closed curve can also be created by snapping to the first point of the curve.
 * Press or the  button to delete the segments already placed, but keep working from the last point.
 * Press or the  button to adjust the current working plane in the orientation defined by the last and the previous point.
 * Press to switch Draft snapping on or off.
 * Press or the  button to finish the command.

 * 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.

Properties
See also: Property editor.

A Draft BezCurve 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 curve. The value will be if  if  or the face cannot be created.
 * : specifies if the curve is closed or not. If the curve is initially open this value is, setting it to will draw a segment to close the curve. If the curve is initially closed this value is , setting it to  will remove the last segment and make the curve open.
 * : (read-only) specifies the continuity of the curve.
 * : specifies the degree of the curve.
 * : (read-only) specifies the total length of the curve.
 * : specifies if the curve 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  is  and if the curve does not self-intersect.
 * : specifies the control points of the curve in its local coordinate system.

View

 * : specifies the size of the symbol displayed at the end of the curve.
 * : specifies the type of symbol displayed at the end of the curve, which can be, , , or.
 * : specifies whether to show a symbol at the end of the curve, so it can be used as an annotation line.
 * : specifies the Draft Pattern with which to fill the face of the closed curve. This property only works if is  and if  is.
 * : specifies the size of the Draft Pattern.

Scripting

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


 * Creates a object with the given list of points,.
 * Each point in the list is defined by its, with units in millimeters.
 * Alternatively, the input can be a, from which points are extracted.
 * If is, or if the first and last points are identical, the curve is closed.
 * If is  the curve is created at the origin.
 * If is, and the curve is closed, the curve will make a face, that is, it will appear filled.
