Hi - please don’t ask the same question in multiple threads.  
Did you read the manual that comes with Bison?  
To get help, please always post relevant files.  
Also, there is contact information for @bison on the Food4Rhino page.

OK, I am sorry about that and I will not do that again.  
Yes, I have read it before but just cannot solve it.

And I will try it again and post the file after some time if it still doesn’t work.

Thank you so much.
