Hello,  
   	  
   	I found in the user guide of Flux about the 3D connectivity problem of thin sheet metal region, which says: 
   	Specificity in 3D: problem of connectivity. (For thin conducting regions) In the presence of holes, the user must create the necessary electric cuts and assign to them to appropriate lines.  
   	Attention: magnetic /electric cuts should not touch the thin regions. 
   	  
   	I wonder how could I create a 3D sheet and a cut on it without touching the region. Could you please explain this a bit? 
   	  
   	Regards,
