Hi, All:
I'm running into a problem, wondering if someone can help.
I am trying to get the underlying curve of an edge, and getting a swig error
message.
Heres' a simplified version of my code( which gets the endpoints of the
curve )
from OCC import BRepBuilderAPI,gp,GeomAdaptor
brepTool = BRep.BRep_Tool();
builder =
BRepBuilderAPI.BRepBuilderAPI_MakeEdge(gp.gp_Pnt(0,0,0),gp.gp_Pnt(1,1,1));
builder.Build();
edge = builder.Edge();
hc = brepTool.Curve(edge);
c = GeomAdaptor.GeomAdaptor_Curve(hc[0]);
p1 = c.Value(hc[1]);
p2 = c.Value(hc[2]);
it prints this message:
"swig/python detected a memory leak of type 'Handle_Geom_Curve *', no
destructor
found."
I have been using the alternative code below that does not give this
message, but doesnt seem to perform as well: I was surprised after running
the code below that it does not seem as fast as the above:
curve = BRepAdaptor.BRepAdaptor_Curve(edge);
pa1 = curve.FirstParameter();
pa2 = curve.LastParameter();
curveType = curve.GetType();
#get first and last points.
p1 = gp.gp_Pnt();
p2 = gp.gp_Pnt();
BRepLProp_CurveTool.Value(curve,pa1,p1 );
BRepLProp_CurveTool.Value(curve,pa2,p2 );
I am using pythonOCC version 0.4 on windows XP pro. Is either of the above
methods preferred?
Thanks in advance!
