How to customize chapter heading in thesis?

Question

I need help in formatting my thesis. I m using isuthesis class. My university guidelines doesnt match with isuthesis CHAPTER HEADING STYLE AND SECTION HEADING STYLE.

aCCORDING TO UNIVERSITY, The format for typing Chapter headings Divisions headings and sub-division headings are explained through the following illustrative examples.

Chapter headings (at the centre of the page) : CHAPTER 1

                  INTRODUCTION

Division heading (Left justified) : 1.1 OUTLINE OF THESIS

Sub-division heading (left justified) : 1.1.2 Literature review.

My thesis code snippet is given here and the output i have attcahed as an image. My latex code gives me CHAPTER HEADING AS --
CHAPTER1. INTRODUCTION ( want this in two line)

and division heading as -- 1.1 Introduction ( want this in upper case)

% Template file for a standard thesis
\documentclass[11pt]{isuthesis}
\usepackage[pdftex]{graphicx}
% Standard, old-style thesis
\usepackage{isutraditional}   \chaptertitle
% Old-style, thesis numbering down to subsubsection
\alternate

%Optional Package to add PDF bookmarks and hypertext links
\usepackage[pdftex,hypertexnames=false,linktocpage=true]{hyperref}
\hypersetup{colorlinks=true,linkcolor=blue,anchorcolor=blue,citecolor=blue,filecolor=blue,urlcolor=blue,bookmarksnumbered=true,pdfview=FitB}
\begin{document}

\newpage
\pagenumbering{arabic}
\include{Body/chapter1}

%\include{Reference/biblio}
\end{document

}

below given is the chpater 1 code.

\chapter{OVERVIEW}

    This is the opening paragraph to my thesis which
    explains in general terms the concepts and hypothesis


    \section{Introduction}

    Here initial concepts and conditions are explained and


    \subsection{Hypothesis}

    Here one particular hypothesis is explained

PLEASE SUGGEST.

Answer 1

In general I would suggest using the \uppercase{}-command. You can put this command into \section{} directly or define your own command. A MWE using documentclass report is shown below:

\documentclass[11pt]{report}

\usepackage{blindtext}

\newcommand{\upsection}[1]{\section{\uppercase{#1}}}

\begin{document}
\chapter{Chapter One}
\blindtext

\section{\uppercase{Section One}}
\blindtext

\upsection{Using own command}
\blindtext
\end{document}

Unfortunately, I do not know whether this is working with isuthesis or not.

Answer 2

If i understood you correct, this should do what you want. But be careful, university requirements are strict. I guess they won't accept your paper at Iowa State University.

Instead of patching a class file, you can use a package like titlesec.

\documentclass[11pt]{isuthesis}
\usepackage[pdftex]{graphicx}
\usepackage{isutraditional}   \chaptertitle
\alternate

\usepackage{etoolbox}
%\tracingpatches
\makeatletter
\patchcmd{\@makechapterhead}{~~~#1}{\\ \MakeUppercase{#1}}{}{}
\patchcmd{\section}{\bfseries}{\bfseries\MakeUppercase}
\makeatother

\usepackage[pdftex,hypertexnames=false,linktocpage=true]{hyperref}
\hypersetup{colorlinks=true,linkcolor=blue,anchorcolor=blue,citecolor=blue,filecolor=blue,urlcolor=blue,bookmarksnumbered=true,pdfview=FitB}
\begin{document}

\chapter{Overview}

This is the opening paragraph to my thesis which
explains in general terms the concepts and hypothesis


\section{Introduction}

Here initial concepts and conditions are
explained and


\subsection{Hypothesis}

Here one particular hypothesis is
explained

%\include{Reference/biblio}
\end{document}

If you want the section headings left aligned, the patch is a little bit different. But to be honest, i don't think it is good practice to use a template that implements special requirements and patching it almost to the standard.

\patchcmd{\section}{\centering\large\bfseries}{\large\bfseries\MakeUppercase}
