TOTAL Sketch provides access to a variety of predefined area line shapes you can add to your sketch as a starting point for areas you create.
If you are sketching a polygon other than rectangle, pentagon, or octagon, first click Draw and select Area line. Then, click on the grid where you want the polygon to be placed. Enter the number of sides for your polygon, up to 20 sides, using the numbers 0‑9 on your keyboard. Next, enter the @ symbol (Shift+2) followed by the length of the walls. Ex.: 12@5 creates a 12‑sided polygon with 5 ft walls.
