Draft BezCurve

Description
The BezCurve tool creates a Bezier Curve (or a piecewise Bezier Curve) from several points in the current work plane. It takes the linewidth and color previously set on the Tasks tab.

The object is created as a single Bezier Curve of degree (number_of_points - 1). This can be changed to a piecewise Bezier Curve of a specified degree after creation using the properties editor. Bezier Curves can be edited using.



How to use

 * 1) Press the  button, or press  then  keys.
 * 2) Click a first point on the 3D view, or type a coordinate
 * 3) Click additional point on the 3D view, or type a coordinate
 * 4) Press  or, or double-click the last point, or click on the first point to finish and close the spline.

Options

 * Press or the  button to finish the spline, leaving it open
 * Press or the  button or click on the first point to finish the spline, but making it closed by adding a last segment between the last point and the first one.
 * 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 check/uncheck the  button. 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 (0,0,0) origin point.
 * Press or click the checkbox to check/uncheck the  button. If continue mode is on, the BezCurve tool will restart after you finish or close it, allowing you to draw another one without pressing the BezCurve button again.
 * Press while drawing to force snapping your point to the nearest snap location, independently of the distance.
 * Press while drawing to constrain your next point horizontally or vertically in relation to the last one.
 * Press or press the  button to remove the existing segments and start the spline from the last point.
 * Press + or press the button to undo the last point.
 * Press or the  button to abort the current BezCurve command.

Properties

 * : Specifies if the Bezier Curve is closed or not
 * : Specifies the degree of the Bezier Curve (or segments)

Scripting
The BezCurve tool can by used in macros and from the python console by using the following function:


 * Create a Bezier Curve object from the given list of vectors. Instead of a pointslist, you can also pass a Part Wire.

Example:

Limitations

 * This tool is not yet generally available. It will be included in a future version.  (post v0.13)
 * The Points Property does not yet appear in the properties list.
