getPointAtDist(dist,point)

Any one show me why I use this function with a closed 3DPolyline but
it is return Acad::eOk when dist> lengthen???

Is the distance less then the polyline length + the length between the last
vertex and the first vertex? In other words, is the distance less then the
polyline's closed path length? If so, then it is doing as it should since
the closing segment is part of the polyline.

I just looked at the source code for AcDb3dPolyline::getPointAtDist() and it
appears that it should definitely error out if the distance is greater then
the polyline's closed path length.

No, the closed Polyline is the polyline what has the first vertex and last vertex same(the first vertex=the last vertex)
