Most venues have rounded or arching boundaries defining their Sections. You can draw this with our designer tool, too.
The trick is, when drawing a Section, to create multiple points across the curvature or rounded border you wish to lay down, as seen above. The more points, the more soft the curvature will look.
If you make a mistake, that's fine! You can always right click to remove the last node you laid down. You can learn more by looking at the status bar at the bottom of the screen while you are on the Section tool.
If you feel it's needed, you can hold the alt key while drawing to disable snapping to other points, or deselect Snap to grid for even higher precision. Don't forget to turn Snap to grid back on after you are done. This will make it easy to lay down rows symmetrically across the chart.
If you had already drawn a section but wish it was smoother, you can always use the Node tool to click on the sides that look more rough and add additional nodes.
Please note that using a Reference chart to draw on top of is always the most effective and fastest way to draw a precise seating chart. You can upload one by dragging an image to the Reference chart property, visible when no object is selected on the right hand of the screen.
Now you are a master of sections. Go ahead and draw a great seating chart.
