Click Add. The Deck Assignment Mode dialog box will disappear, and the RAM Modeler will enter the Deck Assignment Add Layout Mode.

While in Deck Assignment Add Layout Mode, decking may be added by defining a polygon (or polygons) that define areas for the decking. This is done by clicking the mouse to define each vertex point and moving the mouse to define each line in the polygon. Polygon lines must be entered consecutively, and must define a proper polygon. To define the first polygon line, point the mouse to the beginning coordinate of the line, click the left mouse button, move the mouse button to the ending coordinate of the line, and click the button again. For each subsequent polygon line move the mouse to the next vertex and click again to define the next polygon line. Repeat until the polygon is closed. Within decked areas, the polygon lines must fall precisely on beam and wall lines if one-way decking is being added. Beyond the slab edges, the polygon vertices can be placed at any convenient node. As an alternative to clicking on a node, coordinates can be entered directly using the Keyboard Mode Coordinate Entry command. This is convenient when there is no existing node at the location where the deck polygon vertex is to be placed, outside of the perimeter of the structure.

When the polygon definition is complete, the new deck assignment will be made inside the defined polygon.
