In the Text command, what option allows you to automatically create a text string expression from the generated text?

The option that allows you to automatically create a text string expression from the generated text in the Text command is Reference Text. This choice enables the text to be linked to a specific expression or variable in the design, so any updates to that variable will dynamically change the text being displayed. This feature is particularly useful in design automation and parametric modeling, where maintaining consistent and accurate documentation is critical as design parameters change.

Reference Text establishes a connection that allows the text to automatically reflect updates, making it an essential tool for ensuring that design annotations remain accurate without needing manual adjustments. This not only saves time but also minimizes the risk of errors associated with manual text updates.

The other options focus on different functionalities of text creation. Dynamic Text is typically used to create text that can change based on the context but doesn’t imply a direct link to a specific expression like Reference Text does. Static Text refers to fixed text that does not change regardless of design updates, which doesn't provide the automation needed in this scenario. Auto Text generally refers to pre-defined text expansions or formats that do not create expressions like Reference Text does.
