[Tex/LaTex] changing document configuration with lyx

lyx

this is my first time with Lyx and what I wat to do is to change :

  • the "Part" into chapter
  • section 1 to section "ChapterNumber.sectionNumber" (1.1)
  • subsection 1 to "chapterNumber.sectionNumber.subsectionNumber" (1.1.1)
    ….

and I want that those changes remain for the whole document
how should I proceed ?

Best Answer

I assume you are using the default document class, which in LyX is set to article. This class does not have a Chapter style available, so instead of making the changes you have asked for in the article class, I think you should just change document class. In report or book the Chapter style is available, and the numbering of sections and subsections are as you ask.

Hence, go to Document --> Settings --> Document class, and choose Report (Standard class) or Book (Standard class) from the list. Then, for each of your parts, change the style to Chapter in the dropdown menu in the top left of the LyX window.
