Aug 27, 2020 - Suntuf® Corrugated Polycarbonate is lightweight, super tough and easy to install. Use it to cover just about any type of outdoor structure for increased outdoor living area, storage, or shelter. See more ideas about outdoor structure, outdoor living, polycarbonate panels. As the path/ patio will need to follow the surface gradient I then thought the best way to implement the path would be to use a sub-region. The only issue with this however is that in using a sub-region instead of a model in place the path/ patio is not visible in plan views. Attached below is a quick example of how the sub-region is visible in.
