Overview
Wing-Walls are shade objects used to model Vertical Shading that is projecting out Perpendicularly from both Left & Right ends of a Wall so that their Shading Impacts (i.e. reduced Solar Gains) can be SimulatedScreens .
Wing-Walls can be Automatically Created by Hero (recommended) or Manually Created or Overidden by Users depending on the situation (see further details below)
...
Wing Walls 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.

Automatic vs Manual Wing Walls
Wing Walls are a Shading Object (similar to Eaves & Screens) within the Hero Model.
Visual View
...
Within the Visual View Automatic Wing Walls are shown differently to Manual (i.e. User Created) Wing Walls with Automatic Wing Walls having a dotted line (see Left Wing Wall in image to the right), whereas Manual Wing Walls have a solid line (see Right Wing Wall in image below).
Automatic Wing Walls
...
There are situations where Hero can automatically detect that a certain object within the Model should be considered a Wing Wall to another wall. Hero automatically detects Other Walls and Screens as potentially Wing Walls. The Wall or Screen must be Perpendicular to the subject Wall to be considered a candidate to be an Automatic Wing Wall.
E.g: In the Example image to the right a Selected Wall (in Blue) has automatically had two Wing Walls assigned to it by Hero on it’s Left & Right (dotted pink lines) rather than require the User to Manually Create these.
| Tip |
|---|
We recommend you always double-check Automatic Wing Walls as there can occasionally arise situations where Hero’s automatic assessment may not be providing the largest shading impact on a wall and users should exercise user judgement. |
Manual Wing Walls
...
Manual or User Created Wing Walls are sometimes required to model Shading Objects that are not part of the Hero Model such as Fences, Adjacent Buildings and Other such objects on the plan.
E.g: In the Image to the Left a Selected Wall (in Blue) has Automatically had a Right Wing Wall created for it but required a Manual Left Wing Wall to be created by the user to Model the Fence.
Alternative Modelling Method
You could also model the above scenario without the use of Manual Wing Walls using Screens which are also picked up “Automatically” by Hero’s scans similar to other Walls.
E.g. in the example below a Screen was drawn in to model the fence that we modelled as a Manual Left Wing Wall in the previous example. The second image on the right (shown with the Wall Selected) shows that this Fence has been Automatically detected by Hero and an Automatic Left Wing Wall has been created. (This method has the benefits of the Screen being easily edited in position and multipurpose)

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

Screens as Automatic Wing-WallsScreens can also get Auto-Detected by Hero Using Hero’s automatic detection of Screens as Wing -Walls when they lie Perpendicular to a Wall. |

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
Creating
Screens are created using the Screen Drawing mode (Screen & Eave Drawing Modes)
Attaching / Connecting to Walls
Screens currently must be Manually Connected to Walls by the User for their Shading 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 Screen within the Visual View & Screen Data-Grid by 🖱 Left-Click.
Selecting Connections
A Connection Line can be Selected within the Visual View 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

Walls feature, is a highly recommended way to improve your productivity and reduce data-entry errors. This unique feature can be slightly confusing to new users who are used to more Manual Wing Wall style creation experience from other software packages. It is also slightly different to how Screens are used as parallel Vertical Shade Objects (i.e. their “traditional” functionality as Screens inside Chenath) inside Hero where you are required to manually attach them. You don’t need to do that for Screens as Automatic Wing Walls. When you use a Screen to represent a Wing Wall(s) and let Hero automatically detect that Screen (as a Vertical Shade object) and automatically create a Wing Wall Shade object (used in Chenath), you give yourself much greater flexibility and accuracy. Benefits of Screens as Automatic Wing Walls
How To Use Screens as Wing Walls Enter the Height of the Screen as you would for when using it as a Parallel Shading Screen. If the Screen line is within a certain distance to the edge of the Wall (note it can be slightly “in front” of a Wall in which case Hero just caps the Horizontal Offset of the Wing Wall to 0mm) then Hero will automatically calculate and create an Automatic Wing Wall to visual show our best guess at the appropriate Wing Wall. The Wing Wall projection, horizontal and vertical offset values are then updated automatically on model changes such as level heights and wall or shade object position changes. Remember there’s no need to manually Attach Screens to Walls for them to be utilised as Automatic Wing Walls by Hero, we calculate and detect these automatically at the end of certain Hero actions! Attaching Screens to Walls is only required for Parallel traditional Shade Screen model creation where some user judgement is currently required. When are Manual Wing Walls appropriate? There's always a place for overriding wing-walls. The limitations of Chenath (only one wing-wall shade object allowed per wall end) require Hero to select just one of the many possible Wing-Wall shade objects configurations that are possible in a typical design. There will inevitably be times where user-judgement is required to provide a more human educated guess at what would be the appropriate shade object. In these situations, Manual Wing Walls provide a quick and flexible way to lock a Wing-Wall shade object to a Wall . |
WING WALLS IN THE VISUAL VIEW
Creating
Auto-Created Wing-Walls
Hero by default Automatically detects & Creates Wing Walls throughout the Model (see above section) when it detects Walls or Screens nearby that would act as a Left or Right Wing Wall.
Creating Manual Wing-Walls
...
Wing Walls can be Manually Created within the Visual View by 🖱 Left-Clicking one of the Create Wing Buttons that sit next to the Left & Right ends of a Selected Wall in the Visual View.
A Wing Wall is created and can now be further 🖱 Dragged into it’s final desired position (see Moving Section below).
...
Selecting
You can Select a Wing Wall within the Visual View by first Selecting the Parent Wall to make the Wing Wall Visible & then 🖱 Left-Click to Select the Wing-Wall.
If you Select a Wing Wall Row in the Data-Grid, both Wing-Walls will be selected in the Visual View.
...
Deleting
A Wing Wall can be Deleted by:
selecting the Wing Wall within the Visual-View or Data-Grid and pressing
⌨ Delete(noting that if selected in the Data-Grid this will delete both Wing Walls if there are two); orby using the 🖱
Right-ClickContext-menuDeleteaction 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 🖱
Hoveredor Selected & pressing the⌨ DeleteSelecting the Connected Wall Row within the Screen Data-Grid & pressing
⌨ Delete
Moving
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 Screen or Screen Point in a straight ↔ or ↕ direction by holding ⌨ Shift.
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).

Deleting Automatic Wing WallsIf you Delete an Automatic Wing Wall, rather than remove the Wing Wall entirely Hero will set the Wing Wall to Manual & Zero the Projection & Offset of the Wing Wall. This is to prevent another Automatic Wing Wall from being created on subsequent Wall Moves etc. |
...
Moving
The Projection & Horizontal Offset of a Wing Wall can be adjusted in the Visual View.
To adjust the Projection, select the Parent Wall to make the Wing Wall Visible and then 🖱 Drag the End Point (i.e. the Projection Point) of the Wing Wall to it’s desired location.
To move the Horizontal Offset, again ensure the Wing Wall is visible and then 🖱 Drag the Projection Line of the Wing Wall and move it to it’s desired location.
