Hi all,

I'm having problems performing a boolean operation remove lump. I get this error message 131088.

​I have succeeded doing the remove lump on one side of the part but not the other side of the part, but cannot find the origin of the error. 

I did catdua with cleaning 2 errors and restarted Catia, but have the same problem. 

I am using Catia V5 R28. 

Any advice? Thanks in advance!
