Draft BezCurve

Description
The Draft BezCurve command creates a Bezier Curve from several points. It uses the Draft Linestyle set on the Draft Tray.

The command creates a single Bezier curve of degree. It can be transformed to a piecewise Bezier curve, made up of curves of a specified degree, by changing its properties.

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) Click the first point in the 3D view, or type coordinates and press the  button in the related Line task panel.
 * 6) Click additional points in the 3D view, or type coordinates and press the  button in the related Line task panel.
 * 7) Press  or the  button in the related Line task panel, or double-click the last point to finish the command.

Options

 * Press or the  button to finish the curve, leaving it open.
 * Press or the  button to close the curve, that is, a segment will be added from the last point to the first one to form a face. At least four points, a curve of degree three, are required to form a face.
 * Press or the  button to remove the curve segments already placed, but keep editing the curve from the last point.
 * Press or the  button to adjust the current working plane in the orientation of the last point.
 * Press, or  after a point to constrain the next point on the given axis.
 * To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component.
 * Press or click the checkbox to toggle relative mode. If relative mode is on, the coordinates of the next point are relative to the last one; if not, they are absolute, taken from the origin (0,0,0).
 * Press or click the checkbox to toggle continue mode. If continue mode is on, the BezCurve command will restart after you finish the curve, allowing you to draw another one without pressing the command button again.
 * Press or click the checkbox to toggle filled mode. If filled mode is on, a closed wire will create a filled face ; if not, the closed wire will not make a face.
 * the curve should not be filled if it intersects itself, as it won't create a proper face. If the curve is filled but no shape is visible, manually set to  to see the curve.


 * Hold while drawing to force snapping your point to the nearest snap location, independently of the distance.
 * Hold while drawing to constrain your next point horizontally or vertically in relation to the last one.
 * Press + or press the button to undo the last point.
 * Press or the  button to abort the current command; curve segments already placed will remain.

Data

 * : specifies the degree of the Bezier curve or the individual segments.
 * : 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.
 * : 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.
 * do not set to  if the curve intersects itself, as it won't create a proper face.


 * : (read-only) when the curve is closed, indicates the continuity of the curve, or . Otherwise it's.

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 dot, circle, arrow, and tick.
 * : specifies whether to show a symbol at the last point of the curve, so it can be used as an annotation line.
 * : specifies a Draft Pattern with which to fill the face of the closed curve. This property only works if is, and if  is "Flat Lines".
 * : 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 shape is created at the origin.
 * If is, and the wire is closed, the wire will make a face, that is, it will appear filled.
