Hi,
Im trying to make a clone of a deformed primitive spline.
The code im using is:

    
    
    
    
    // obj1 is a Arc Spline (that has a bend deformer as its child)
    
    
    
    
     BaseObject *object = op->GetAndCheckHierarchyClone(hh, obj1, HCLONE_ASSPLINE, &dirty, 0, false);
    
    
    
    
     if(!dirty) return object;
    
    
    
    
     SplineObject *spline = static_cast<SplineObject*>(object)->GetRealSpline();
    
    
    
    
     if(!spline)   
     {  
      GePrint("Spline is null");  
      return NULL;  
     }

The result of that returns "Spline is null in the console when I have a deformer as a child of the spline. If i remove or de-activate the deformer, the spline variable is valid and my plugin works like it should.
What am I doing wrong?
Thanks

A deformed spline is no longer a SplineObject, it's a LineObject. You might be able to use HCLONE_ASLINE. I prefer to use HCLONE_ASIS, SendModelingCommand(MCOMMAND_CURRENTSTATETOOBJECT) and then GetRealSpline() on that. If I get something back I consider it a spline object.
The drawback is that once a spline is converted to a Line it loses its interpolation option, it's just a couple of line segments. So you'll lose precision when using e.g. GetSplineTangent(). Therefore you might want to provide a variant without the current state to object, to only accept undeformed splines.

Thanks Mikael,
Worked a charm I used the HCLONE_ASIS/SendModelingCommand way
