Hi!
I have created a Sweep Nurbs in a Plugin with the codes
env = SplineObject::Alloc(3,Tlinear);
spl = SplineObject::Alloc(RiverNPts, Thermite);
osweep = BaseObject::Alloc(Osweep);
/// Initialisation of the different components of the splines spl and env

spl->InsertUnder(osweep);
env->InsertUnder(osweep);
Does somebody know how to activate the parallel movement in a Sweep Nurbs Object?
Thanks in advance,
