A single-text object is created using the active text style. You can change the formatting of a single-line text object by changing the text style associated with it, or by editing the properties of the single-line text object directly. You cannot apply formats to individual words and characters with single-line text objects.
To change a text style associated with an individual single-line text object, set the TextStyleId property to a new text style. Once you have changed the text style, you must regenerate the drawing or update the object to see the changes in your drawing.
