Hi,
I'm pretty new to pythonocc and am impressed by it. Thanks for your work!
After I ran across splines the other day I am now trying to use
opencascade and pythonocc for curve definitions and anaylsis. But I
could not figure out how to concat two splines into one. The mailing
list and searching the internet only showed examples on how to do it in
C++, and I can not adopt it to python! The function I'd like to use is
GeomConvert().ConcatG1(), but I can't figure out how to declare the
third parameter of type Handle_TColGeom_HArray1OfBSplineCurve. I always
get a constructor or type error. See the listing of my little sample
programm.
#Line
L2 = GC_MakeSegment(L1.Lin(),0,8)
L3 = Geom_TrimmedCurve(L1.GetHandle(),0,8)
L3_S =
GeomConvert().CurveToBSplineCurve(L3.GetHandle(),Convert.Convert_TgtThetaOver2
)
#Circle
P2 = gp_Pnt(2,8,0)
N = gp_Dir(0,0,-1)
C1 = Geom_Circle(gp.gp_Ax2(P2,N),2)
C3 = Geom_TrimmedCurve(C1.GetHandle(),0,math.pi/2)
C3_S =
GeomConvert().CurveToBSplineCurve(C3.GetHandle(),Convert.Convert_TgtThetaOver2
)
#concat
curves = TColGeom_Array1OfBSplineCurve(0,1)
curves.SetValue(0,L3_S)
curves.SetValue(1,C3_S)
print curves.Length()
tol = TColStd_Array1OfReal(0,0)
tol.SetValue(0,0.0)
newCurve = Handle_TColGeom_HArray1OfBSplineCurve()
GeomConvert().ConcatG1(curves, tol, newCurve, False, 0.0)
Regards,
Nathan
