I have an iges file exported from CATIA. It contains only four curves. In CATIA, they are named as "DB_71", "DB_72", "DB_73" and "DB_74". When I read this file using OCAF, I get four names as "DB_71 (0)", "DB_72 (0)", "DB_73 (0)", "DB_74 (0)", I just want to know what's the "(0)" meaning, can we omit this sub string?
PS: In fact, I also find some names such as "0(0)" from my testing iges files. These names are meaningless.
My name reading code lists as follows:
TDF_Tool::Entry( label, entry );
if ( label.FindAttribute( TDataStd_Name::GetID(), N ) )
name = new char[N->Get().LengthOfCString()+1];
N->Get().ToUTF8CString( name );
Any suggestion is welcome. Thanks in advance.
