Revit Annotations

Why doesn't the Level Head text change when I change the text style?!!
Why doesn't the Section Head text change when I change the text style?!!
Where do I change the boundary line of the callout?!!

Many are confused by this. So I'm going to try and explain in plain English. Some annotations are controlled in the Project file (.RVT) that you're drawing the model in. Others are controlled partially in a separate Family file (.RFA). When they have a FAMILY FILE involved you will have to load (File-Load From Library-Family) it into your PROJECT FILE. I'll specify in the following explanations.

Text Style: Controlled in the PROJECT FILE.
This is only for the notes and titles. You do this by editing an existing instance into your new style.

Dimension Style: Controlled in the PROJECT FILE.
These are made from the Settings-Annotation drop down menu. You can also duplicate and edit an existing dimension. The text style for the dimensions is controlled from the dimension style editor.

Level Head: Controlled in a FAMILY FILE and the PROJECT FILE.
This is an Annotation Family. You have to open it and edit the text inside the family. To find the file name of the family you want to edit; click on a level-properties-Edit/New-Other-Level Head (you just have to write it down or memorize it). The level linetype is controlled in the PROJECT FILE by clicking Properties-Edit/New-Line Pattern.

Grid Head: Controlled in a FAMILY FILE and the PROJECT FILE.
The same as Level Head. The grid linetype is controlled in the PROJECT FILE by clicking Properties-Edit/New-Line Pattern.

Section Bubble: Controlled in a FAMILY FILE and the PROJECT FILE.
Again, these are an Annotation Family. They consist of two families which have to be edited separately. One would be the bubble and one would be the tick mark at the other end. The section linetype is controlled in the PROJECT FILE through Object Styles-Annotation-Section Line.

Callout Bubble: Controlled in a FAMILY FILE and the PROJECT FILE.
These are similar to Section tags but only have one family. The callout boundary line is controlled in the PROJECT FILE through Object Styles-Annotation-Callout Boundary.

Elevation Bubble: Controlled in the PROJECT FILE.
The Settings dropdown menu-Elevation Tags and edit away.

Annotations should be setup in your template file (.RTE).
