You can use the Deck tool to build a deck of virtually any shape and size.
Decks are inserted on the current building location rather than the terrain. This ensures your deck is created at the correct height, and makes it possible to create multi-level decks.
Once you’ve inserted a deck you can move, stretch, rotate, raise or lower it if needed, as well as edit its properties, which include settings for posts, railings and skirting.
To create a deck:
In the Building Locations drop box, select the location you want to associate the deck with. The height of a deck is determined by the Height above current location variable in the deck properties. You can edit this value after the deck has been inserted if necessary.
Select Insert > Landscape > Decks > Decks, or click the Decks button on the Landscape toolbar and select Decks.
In the catalog, select the decking material you want to use.
Select a start point for the deck outline. Continue selecting points until the outline is defined. (You do not have to select the start point again because the last point you pick is always closed back to the start point.)
Right-click and select Finish.
