Summary0000068: DXF Import
DescriptionWhen I import a DXF File the arcs are not imported correct.
Additional InformationI have added an example depending of a couple of lines and arcs.

Lines are connected to Lines as expleced
Arcs with lines are connected to lines at one point but the direction of the arc seems to be wrong.
Arcs with arcs I cant guess...


Find my Testfile Spant.dxf attached

The method drawArc() can be implemented this way:
def drawArc(arc):
    "returns a Part shape from a dxf arc"
    v=FreeCAD.Vector(arc.loc[0],arc.loc[1],arc.loc[2])
    firstangle=(arc.start_angle/180)*math.pi
    lastangle=(arc.end_angle/180)*math.pi
    circle=Part.Circle()
    circle.Center=v
    circle.Radius=arc.radius
    return circle.toShape(firstangle,lastangle)


BTW, you can remove the line from PyQt4 import QtGui at the top. The script then can be used without having installed python-qt.
