Hi
Read Rhapsody documentation; it is both, handmade code with tool generation the "envelop".
Good luck

Subject: [UML Forum] Writing code from UML diagrams manually
Hi there:
I'm looking for a resource, a book, a blog, something, that could help me in writing code out of UML diagrams, but manually, all I find are automatic tools that do the job. Perhaps I will be interested in these kind of things in the future, but for now, I want to do it manually.
Thanks in advance,
Rafael

you need. You would do exactly the same things by hand that the
automated transformation engine does.
The obvious push-back is: Why would you want to do that manually when
there are commercial transformation engines to do it automatically?
That's sort of like saying, "I don't want to use a 3GL because I am a
masochist and want to write code in Assembler." B-)

If a commercial transformation engine does not produce what you expect,
then there are only two possibilities: (A) the UML design model itself
is incorrect and (B) the transformation engine is broken.
The only exception that I know of is optimization. The transformation
engine will do the correct thing, but the code just isn't fast enough
because the transformation engine designers mat not handle some special
situations properly for nonfunctional requirements. That's because
optimization is so complex since the engine has to deal with the entire
computing space rather than just a specific machine's instruction set,
like a 3GL compiler. Most of the commercial tools are pretty good now
and will provide adequate performance for 99+% of IT applications and
90-95% of R-T/E applications. For that 5-10% of situations in R-T/E, you
might look at a tool like PathMate, which is aimed at the high
performance niche and allows you to customize the translation rules via
templates.
