## Steps

### Step 1: Understand Cross-Section Requirements

If the section of your deck varies from the beginning to the end of your project, you should define at **least two** cross-sections.

However, in this particular project, the deck sections remain consistent throughout. Thus, it is adequate to define **a single** cross-section to generate this deck.

### Step 2: Navigate to Cross Section

Navigate to **Deck > Cross Section** in the tree view.
