[Tex/LaTex] KOMA-Script scrbook: How to remove period after part

Question

I'm using scrbook to typeset a document and I'm using \part for formatting the parts of it.

The default output renders \part{Mytitle} into

Part I.

Mytitle

Now I'd like to get rid of the period after "Part I." In the KOMA-Script guide I have only found options to generally switch off punctuation after every part, chapter, section etc.

So I tried \renewcommand{\thepart}{\Roman{part}} but this strangely still puts a period after the roman number. However, \renewcommand{\thepart}{\arabic{part}} and \renewcommand{\thepart}{\arabic{part}.} produce the expected difference.

So what is so special with roman numbering here?

Answer 1

There is not automatic solution to this, but it is not hard to redefine the format of the part headings. The default is

\newcommand*{\partformat}{\partname~\thepart\autodot}

you just need to redefine this removing the \autodot.

\documentclass[numbers=enddot]{scrbook}

\renewcommand*{\partformat}{\partname~\thepart}

\begin{document}
\part{My part}
\chapter{My chapter}
\section{My section}
\part{My part}
\chapter{My chapter}
\section{My section}
\end{document}
