This code will check the length of display_text and multiply it by the size of a single character (8.3). Change the value of display_text back to the original text. Our completed code should look as follows:display_text="Good Job!";

linear_extrude(5)

text(display_text, font="Courier New:style=Regular");

echo(len(display_text));

cube([len(display_text)*8.3,9,2]);

Hit F6 or click the Render button. Verify that the backing plate covers all the text:

Figure 5.15 – Dynamic backing plate

To use our dynamic backing plate code with different text, we can simply change the value of display_text and render our design. Let's do just that. Change the value of display_text to the following:display_text="Best in Class!";
