Description
This tool converts Draft Wires to Draft BSplines, and vice-versa.
How to use
- Select a Draft Wire or a Draft BSpline. The tool is disabled if no object is selected.
- Press the
Draft WireToBSpline button.
A new object will be created; the original object will not be modified.
Note: if a closed wire with sharp edges is converted to 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 DataMake Face to false to see the new shape, or set DataClosed to false to create an open shape.
Options
There are no options for this tool. Either it works with the selected object or not.
Scripting

There is no programming interface available for the WireToBSpline tool, however, creating a new object from the points of another is simple.
The Points attribute of an object is a list with the points that compose that object; this list can be passed to functions that build geometry.
Each point is defined by its FreeCAD.Vector.
If the active object is a wire:
import FreeCAD,Draft
points = FreeCAD.ActiveDocument.ActiveObject.Points
Draft.makeBSpline(points)
- if the active object is a bspline
import FreeCAD,Draft
points = FreeCAD.ActiveDocument.ActiveObject.Points
Draft.makeWire(points)
