The software uses several different text types, standard text, item text and autotext.
Item text is linked to a specific construction or drawing element and shows this element with a line between text and object. While you position item text, an automatic description is added depending on the element.
Autotext is used in 2D symbols, title blocks and wherever project and view properties or other project specific settings on which autotext reacts should be automatically updated. E.g. if you change the project name, autotext in a title block would always show the current value whereas standard text would have to be changed manually.
