NC CODE WARNING
In the postprocessor, some fields permit mathematical expressions to be embedded, delimited by { and } characters.
If the generated NC program contains these characters (for example as part of a part name , material name etc) then Primecut will attempt to erroneously evaluate an expression and will likely show this error.
the solution is to avoid these characters in part names etc. (Primecut now filters these characters out when importing parts.)
