# Select a [[Draft Wire|Draft Wire]] or a [[Draft BSpline|Draft BSpline]]. The tool is disabled if no object is selected.

# There are several ways to invoke the command:

#* Select the {{MenuCommand|Modification → [[Image:Draft_WireToBSpline.svg|16px]] Wire to B-spline}} option from the menu.
# A new object is created.


==Notes==
A new object will be created; the original object will not be modified.


{{Emphasis|Note:}} if a closed wire with sharp edges is used to create a spline, the new object may have self intersecting curve segments, and may not be visible in the [[3D view]]. If this is the case, manually set {{PropertyData|Make Face}} to {{FALSE}} to see the new shape, or set {{PropertyData|Closed}} to {{FALSE}} to create an open shape.
* The command may result in a closed, self-intersecting [[Draft_Wire|Draft Wire]] or [[Draft_BSpline|Draft BSpline]] with a face. Such an object will not display properly in the [[3D_view|3D view]]. Its {{PropertyData|Make Face}} property, or its {{PropertyData|Closed}} property, must be set to {{FALSE}}.


==Options==
==Scripting==

There are no options for this tool. Either it works with the selected object or not.

To convert a wire to a bspline, or vice versa, pass the {{incode|Points}} property of the source object to the {{incode|[[Draft_BSpline#Scripting|make_bspline]]}} method, or respectively the {{incode|[[Draft_Wire#Scripting|make_wire]]}} method, of the Draft module.
There is no programming interface available for the WireToBSpline tool; however, creating a new object from the points of another is simple.

The {{incode|Points}} attribute of an object is a list with the points that comprise that object; this list can be passed to functions that build geometry. Each point is defined by its {{incode|FreeCAD.Vector}}, with units in millimeters.


Example:
Example:

Beskrivning

The Draft WireToBSpline command converts Draft Wires to Draft BSplines and vice versa.

Converting a Draft Wire to a Draft BSpline, and a closed Draft BSpline to a closed Draft Wire

Bruk

  1. Select a Draft Wire or a Draft BSpline.
  2. There are several ways to invoke the command:
    • Press the Wire to B-spline button.
    • Select the Modification → Wire to B-spline option from the menu.
  3. A new object is created.

Notes

  • The command may result in a closed, self-intersecting Draft Wire or Draft BSpline with a face. Such an object will not display properly in the 3D view. Its DataMake Face property, or its DataClosed property, must be set to false.

Scripting

Skript

To convert a wire to a bspline, or vice versa, pass the Points property of the source object to the make_bspline method, or respectively the make_wire method, of the Draft module.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

p1 = App.Vector(1000, 1000, 0)
p2 = App.Vector(2000, 1000, 0)
p3 = App.Vector(2500, -1000, 0)
p4 = App.Vector(3500, -500, 0)

base_wire = Draft.make_wire([p1, p2, p3, p4])
base_spline = Draft.make_bspline([-p1, -1.3*p2, -1.2*p3, -2.1*p4])

points1 = base_wire.Points
spline_from_wire = Draft.make_bspline(points1)

points2 = base_spline.Points
wire_from_spline = Draft.make_wire(points2)

doc.recompute()
