LyX ⇒ Cross reference as part.section.#

[-S8-]

Hi to all,
it bothers me spending my first post asking for help, but here I am.

I'm using the article document class and I structured my work in Part/Section/Subsection; using the command \@addtoreset{section}{part} I reset the section numbering for each part. When I use cross-reference for formulas, images, etc. it gives me the format section.#, but it can be misleading due to the reset, so it will be preferable to have part.section.# format.

I think I have to edit the refstyle package or use a preamble, but I don't know how.

Can someone help me?
Thank you

Hi,

you could redefine \thesection:

Code: Select all

\renewcommand*{\thesection}{\thepart.\arabic{section}}

Or use the chngcntr package and \counterwithin, or if you use amsmath,

Code: Select all

\numberwithin{section}{part}

instead of \@addtoreset.

Thank you! I've tried both options and it works!


Actually they change also the TOC and all section and subsection in the part.section format, but I just want to redefine the cross-references. That's way I think the problem is in the refstyle package.
Now I realize that I don't know if what I'm asking is possible (in an easy way).

Anyway, Thanks

Perhaps think again about it. How do you see a difference then between section 2 in part 5 and section 2 in part 4? It would be consistent, if you would use the part number with section number in references, if you would use the part number in the section number as well. Note that you can refer to sections as well. It would be strange to see "Section 2" a third time (in part 3), but refer to it as Section 3.2. And numbers in the table of contents are of course references.

Hi, I managed to obtain what I wanted. I've used the following preamble:

Code: Select all

\renewcommand{\thepart}{\Roman{part}}
\renewcommand{\theequation}{\thepart.\thesection.\arabic{equation}}
\renewcommand{\thefigure}{\thepart.\thesection.\arabic{figure}}

So now I can cross reference formulas and images as part.section.number.

However I'm still thinking about your advice to number in the same way sections.
