I have a list of curves imported from a DWG. These curves used to be lines and arcs in Civil3D for building pads. I want to organize the points on these curves so that they can enclose. here is my code:

def SortList(c:var[])  
{  
SortedList = {};  
i = 0;  
cnt = List.Count©;  
return = [Imperative]  
{  
while (i\<cnt)  
{  
sp = c[0].StartPoint();  
ep = c[0].EndPoint();  
sp1 = c[i].StartPoint();  
if(sp1==sp)  
{  
c=List.DropItems(c,1);  
SortedList[i] = sp1;  
i=i+1;  
}  
elseif(sp1==ep)  
{  
c=List.DropItems(c,1);  
SortedList[i] = sp1;  
i=i+1;  
}  
else  
{  
c=List.DropItems(c,1);  
i=i+1;  
}  
}  
return = SortedList;  
}

};  
SortList(curves);

Archi-lab has a node Group Curves that should do just that.
