Periodic Blocking
 

Dear Sir or Madam,

I am trying to extrude somemesh in order to get a 360° from a 6° piece.
With some geometries I just don't mange to get it, cause it appears the message "segmentation violation".
This message is quite clear, but it does not let me understand what did I do wrong.
Can anyone help me to understand what are the needed requirements in order to get a successfull extrusion?
I have a 6° piece which is good meshed and all the quality requirements are fulfilled.So It can be that I did something wrong in the association.
Any help and suggestion would be appreciated.
I can mail my geometry.
Thank you in advance.
