The Deck tool is used to design outdoor decks with optional railings as part of your exterior layout. This tool allows you to create custom deck shapes and define important structural and visual details. Adding a deck to your design helps you plan outdoor living spaces accurately and visualize how they connect to the main building.

To use the Deck tool, select it from the Deck tab in the main toolbar and draw the deck shape using the available draw methods. In the Properties panel, you can set the deck height, enable skirting, and adjust the handrail height and spacing if railings are included. After placement, you can resize the deck by dragging its edges and apply different materials and colors in the 3D view to match your exterior design.
