Each individual line of text is a distinct object when using single-line text. To create a single-line text object, you create an instance of a DBText object and then add it to either the block table record that represents Model or Paper space. When you create a new instance of a DBText object, you do not pass the constructor any parameters.
The following example creates a single-line text object in Model space at the coordinate (2, 2, 0) with a height of 0.5 and the text string "Hello, World.".
