# Replace \part of the appendix of Legrand Orange Book with letters of the alphabet instead of arabic numbers

I would to obtain, using the Legrand Orange Book source and his structure.tex file, an appendix (in Italian language) done only with the letters of the alphabet.

So for example:

The several parts, different from the appendix, must to start with the arabic numerals from 1, 2, 3, etc. With my long source structure.tex with many different \usepackage I can only do this after many attempts.

\pagenumbering{roman}%<------for the preface
\pagenumbering{arabic}%<------for the parts


and to have an \part+\chapter into appendix (\usepackage[all options]{appendix}) with all the alphabetical letter I have added only:

\appendix
\part{\textcolor{ocre}{\textsc{Appendice}}}
\chapter{Richiami di formalismo vettoriale}


but I have always an arabic number and I have not the letter A. I have made many attempts but I have not succeeded as can be seen from the image. Thank you in advance for yours help.

• Does the file chapter_head_9.pdf contain the number 5? – Sigur May 22 '18 at 21:18
• @Sigur No, it is a picture. Should I also insert the image in pdf? – Sebastiano May 22 '18 at 21:21
• I supposed that the number could come from that image. Sorry. – Sigur May 22 '18 at 21:28
• @Sigur Into the code there is \chapterimage{chapter_head_9.pdf} % Chapter heading image. – Sebastiano May 22 '18 at 21:32
• Yes, I know. What is the image content? Maybe the number 5 is in this image, so you can not change it to roman, except if you edit that image. – Sigur May 22 '18 at 21:33

1. Undo the changes in structure.tex from your previous question regarding part numbering or use the original structure.tex.
2. Add this to your preamble or at the end of structure.tex:

 \documentclass[11pt,fleqn]{book}

\input{structure}
%%%NEW
\renewcommand{\thepart}{\arabic{part}}%part numbering in arabic

\appto\appendix{%
\renewcommand{\thepart}{\Alph{part}}% A,B,C
\renewcommand{\theHpart}{\Alph{part}}% for hyperref
%%%% END NEW
\begin{document}


This assumes that the appendix is at the end of the document.

A general remark: You are using a rather complex template from a commercial site. You can't handle this template and can't create minimal examples from it. I don't think that it is okay to expect free support in such a case. I also think that it is quite ineffective to spent hours on questions if you don't have the knowledge to create sensible minimal examples. See also Why should you avoid using (complex) templates?.

• First of all, I thank you for your support and for the exhaustive and effective answer. Everything works perfectly. On this site I have to know many things and the suggestions are welcome, hoping to remember them all. Well I understand your directions but all I'm doing is for the memory of my beloved and dear dad that I miss so much. I thank you and everyone. – Sebastiano May 25 '18 at 20:00

Replace

\arabic{...}


with

\Alph{...}

• If I replace for the \part from \arabic{...} with \Alph{...} hence all parts are all with alphabetical letters. – Sebastiano May 24 '18 at 7:06
• @Sebastiano Obviously you did it at the wrong place, but without MWE ... – TeXisFun May 24 '18 at 10:04
• @Sebastiano No, there are more changes – TeXisFun May 24 '18 at 22:18
• If you add a \chapter{...} there are many errors into code main.tex in attachment. For example \part{\textcolor{red}{\textsc{Appendice}}} \chapter{Richiami di formalismo vettoriale} %\pagenumbering{roman} \appendix \renewcommand{\thepart}{\Alph{part}} \setcounter{part}{0} \chapter{Richiami di formalismo vettoriale}, this not work. I have always an arabic number. – Sebastiano May 24 '18 at 22:19
