Hi Denise!
Great question! While the map tool doesn’t support creating a fully triangular shape, there’s a workaround to get the effect you’re looking for! You can upload a custom background image with a triangle outline or any design that shows the balcony shape, and then build your map layout right on top of it. This way, you’ll have the triangle as a guide for placing your booths, points, or other elements.
Let us know if you’d like help with setting it up—we’re here to make mapping easier for you!
