True - this is the way to work with components in McStas - to include  
them in instrumentfiles. - As described in the documentation, McStas  
includes code-generation and a big c-file is compiled from instrument  
and component parts.

You _have_to_ recompile the instrumentfile including your (modified)  
component:

If you are running McStas using mcrun on commandline, add the -c  
parameter. From mcgui, choose File->Compile Instrument.


Best regards,
