Hi,
    I already had problems with this type. We (G10-LCA) know this 
problem with this type. The real problem it's with arc type. We have 
some problems to convert between the way that mapserv draw arcs and the 
Oracle Spatial store the arc type. We are stunding the best way to do 
this convertion.
    I have only two question, what function you use to generate this 
type? When I used oracle spatial function SDO_BUFFER I had this problem. 
And what do you what to draw?

    Some help you can report me.
