Screens are Vertical Shade Objects that are Connected to Walls they are in Parallel to so that their Shading Impacts (i.e. reduced Solar Gains) can be Simulated.
Screens should be used to model Fences, Balustrades, Adjacent Buildings as well as any Opposing Walls (see Opposing Wall Screens section below).
Screens are modelled as Line like objects within Hero, and must be Manually Connected by the User to each Wall that the User determines they may shade.

Screensof& OpeningsNote all Openings (Windows & Doors) on a Wall will also have the Screens of their Parent Walls applied to them during Simulation |
...
| Tip |

Screens as Wing-WallsScreens can also get Auto-Detected by Hero as Wing-Walls when they lie Perpendicular to a Wall. For more details see: Wing Walls |

Modelling Screens over Multiple LevelsCurrently if a Screen’s Height is such that it stretches across multiple Levels, it must be modelled separately on each Level with the Total & Top Heights adjusted as required relative to each Level. In future versions of Hero, we will move to make Screens Level-Independent and allow Levels whose heights are sufficient to project into other Levels shown so that you don’t need to duplicate Screens across multiple levels (see our Trello Features Roadmap for further details). |

Opposing Wall Screens
Screens should be modelled for opposing Walls within the same Model as currently Hero does not auto-detect this (coming soon).
E.g: In the example below each Wall of the Courtyard has a Screen created for each of the Opposing Walls and this Screen is connected to the Opposing Wall.
...
SCREENS IN THE VISUAL VIEW
...
Screens are created using the Screen Drawing mode (Screen & Eave Drawing Modes)
...
Attaching / Connecting to Walls
...
There are a variety of ways to Attach a Screen to a Wall which are detailed further in the Attach Drawing Mode section of Screen & Eave Drawing Modes
...
Connection Lines
...
When a Screen & Wall are Connected, a Connection Line is shown between them on the Visual View, and the Wall is added as a row within the Screen Data-Grid.
