Macro HealArcs/es

A veces los arcos se transforman en BSplines, por ejemplo cuando se les aplica operaciones de escala. Esta macro vuelve a crear arcos válidos a partir de ellos. Útil antes de exportar a DXF

try:
    import DraftGeomUtils as fcgeo
except:
    from draftlibs import fcgeo
import FreeCAD,FreeCADGui,Part

sel = FreeCADGui.Selection.getSelection()
if not sel:
    FreeCAD.Console.PrintWarning("Select something first!")
else:
    removeList = []
    for obj in sel:
        ed = obj.Shape.Edges[0]
        arc = fcgeo.arcFromSpline(ed)
        if arc:
            Part.show(arc)
            removeList.append(obj.Name)
    FreeCAD.ActiveDocument.recompute()
    print "removing ",removeList
    for n in removeList:
        FreeCAD.ActiveDocument.removeObject(n)
