Overview
What they are…they are shading devices in front of a wall
· Screens attached to walls will shade any Openings on that Wall
Screens as Wing-Walls
Screens are Vertical Shade Objects that are Connected to Walls so that their Shading Impacts (i.e. reduced Solar Gains) can be Simulated
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.

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

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). |

SCREENS IN THE VISUAL VIEW
...
Screens are created using the Screen Drawing mode (Screen & Eave Drawing Modes)
...
Attaching / Connecting to Walls
Given that only 3 Screens are only able.
Walls Screens currently must be Attached to Screens Manually Connected to Walls by the User for their impacts to be modelledShading Impacts to be Simulated.
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.
The Connection Line is only Visible within the Visual View when the Wall or Screen is Selected or 🖱 Hovered
.

Selecting
Selecting Screens
You can Select a Ceiling Fan or Penetration Screen within the Visual View . Penetrations can also be selected within the & Screen Data-Grid and this will be reflected by 🖱 Left-Click
.
Selecting Connections
A Connection Line can be Selected within the Visual View .
Ceiling Fans & Penetrations also share the common context-menu actions of Select Parent (which will select the Parent Zone of the Zone Item) which can also be called by 🖱 Double Left-Clicking
the Zone Item.
...
once is Visible (see above) by 🖱 Left-Click
The Connected Wall Row of a Screen within the Screen Data-Grid is also analogous to selecting the Connection within the Visual View
...
Deleting
Deleting Screens
The Screen itself can be deleted by:
selecting the Screen within the Visual-View or Data-Grid and pressing
⌨ Delete
; orby using the 🖱
Right-Click
Context-menuDelete
action within the Visual View;
Deleting Connections (Disconnecting Screens & Walls)
A Screen can be Disconnected (i.e. it’s Connection is Deleted) from a Wall through several means including:
Selecting the Connection Line between the Screen & Wall (shown in the Visual View when a Wall or Screen is 🖱
Hovered
or Selected & pressing the⌨ Delete
Selecting the Connected Wall Row within the Screen Data-Grid & pressing
⌨ Delete
...
Moving
Zone Items Screens can be moved in the Visual View by selecting them and then 🖱 Dragging
them into their position.
...
, and likewise their Start & End Points can be moved in a similar fashion.
You can move a Zone Item Screen or Screen Point in a straight ↔ or ↕ direction by holding ⌨ Shift
.

Modelling Screens over Multiple LevelsCurrently if an object we model as a Screen’s height is such that it stretches across multiple Levels, it must be modelled individually 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). |
...
Parallel View of the Screen
Screens are modelled within the Chenath Simulation as a Vertical Shade Object Parallel to the Connected Wall. The Projection of the Screen from the Wall is based on the Parallel Distance between the Centre of the Wall & the Centre of the Screen.
Therefore Screens that have an angle different to any Connected Walls may not be Simulated as they look Visually, but rather to their Parallel View. This Parallel View is shown as a thin line when a Connected Wall is selected in the Visual View (see image below).
