The shape generated by makepipe is weird.

[JOE_FU]

I defined a shape of wire and a shape of face.
I want to get the shape by using makePipe.
But the final shape is weird.What's wrong with it?

No FreeCAD info, no file attached, no exact step by step description - how can we help? Perhaps you can try to find a solution here: http://cdn2.spiegel.de/images/image-730 ... -73031.jpg

Sorry, it's my fault. I just posted my code.

Code: Select all

class ConformalArea:
    def __init__(self, obj):
        obj.addProperty("App::PropertyVectorDistance", "Point1", "Object of a ConformalArea",
                        "Point1 of the ConformalArea").Point1 = FreeCAD.Vector(0.86, 0.5, 0)
        obj.addProperty("App::PropertyVectorDistance", "Point2", "Object of a ConformalArea",
                        "Point2 of the ConformalArea").Point2 = FreeCAD.Vector(0.86, 0.5, 2)
        obj.addProperty("App::PropertyAngle", "starAngle", "", "").starAngle = 30
        obj.addProperty("App::PropertyAngle", "endAngle", "", "").endAngle = 90
        obj.addProperty("App::PropertyFloat","Radius","","").Radius = 1
        obj.Proxy = self

    def execute(self, fp):
        line = Part.makeLine(fp.Point1, fp.Point2)
        linePath = Part.makeCircle(fp.Radius + 0.001, FreeCAD.Vector(0, 0, fp.Point2.z), FreeCAD.Vector(0, 0, 1),
                                   fp.starAngle, fp.endAngle)
        path = Part.Wire(linePath)
        fp.Shape = path.makePipe(line)




class Line:
    def __init__(self,obj):
        obj.addProperty("App::PropertyVectorDistance", "Point1", "Object of a ConformalLine","Point1 of the ConformalLine").Point1 = FreeCAD.Vector(0.86, 0.5, 0)
        obj.addProperty("App::PropertyVectorDistance", "Point2", "Object of a ConformalLine","Point2 of the ConformalLine").Point2 = FreeCAD.Vector(1.7, 1, 0)
        #obj.addProperty("App::PropertyVectorDistance", "Point1", "Object of a ConformalLine","Point1 of the ConformalLine").Point1 = FreeCAD.Vector(0, 0.5, 0)
        #obj.addProperty("App::PropertyVectorDistance", "Point2", "Object of a ConformalLine","Point2 of the ConformalLine").Point2 = FreeCAD.Vector(2, 1, 0)
        obj.Proxy = self

    def execute(self, fp):
        fp.Shape=Part.makeLine(fp.Point1,fp.Point2)



obj1 = FreeCAD.ActiveDocument.addObject("Part::FeaturePython","ConformalArea")
ConformalArea(obj1)
obj1.ViewObject.Proxy=0
FreeCAD.ActiveDocument.recompute()

obj2 = FreeCAD.ActiveDocument.addObject("Part::FeaturePython","Line")
Line(obj2)
obj2.ViewObject.Proxy=0
FreeCAD.ActiveDocument.recompute()

path=Part.Wire(obj2.Shape)

obj=path.makePipe(obj1.Shape)
Part.show(obj)

At the end of your script :

Code: Select all

obj=path.makePipe(obj1.Shape)

Here, obj1.Shape is a shell.
You should explicitly use a wire or an edge:

Code: Select all

obj=path.makePipe(obj1.Shape.Wires[0])

Thank you very much.It is normal.But why is this shape not closed?

When I use the makePipeShell function, why are some models closed and some models not closed?
