How to change styles in your drawings, style library, design data and templates.
I have created this handy guide for the following situations.
Situation 1: You want to alter a drawings appearance (Local Styles and Standards),
You have a drawing already created and you want to alter the drawing styles and standards.
Situation 2: You want to alter a drawings appearance and save the changes to the library and to your templates so that all drawings can use them.
Hope this helps.
