Eaves

Overview

Eaves are Horizontal Shade Objects that are Connected to Walls so that their Shading Impacts (i.e. reduced Solar Gains) can be Simulated

Eaves 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.


Eaves & Openings

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


EAVES IN THE VISUAL VIEW


Creating

Eaves are created using the Eave Drawing mode (Screen & Eave Drawing Modes)


Attaching / Connecting to Walls

Eaves 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 an Eave to a Wall which are detailed further in the Attach Drawing Mode section of Screen & Eave Drawing Modes


Connection Lines

When an Eave & Wall are Connected, a Connection Line is shown between them on the Visual View, and the Wall is added as a row within the Eave Data-Grid.

The Connection Line is only Visible within the Visual View when the Wall or Eave is Selected or 🖱️ Hovered.


Selecting

Selecting Eaves

You can Select an Eave within the Visual View & Eave 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 an Eave within the Eave Data-Grid is also analogous to selecting the Connection within the Visual View


Deleting

Deleting Eaves

The Eave itself can be deleted by:

  • selecting the Eave within the Visual-View or Data-Grid and pressing ⌨ Delete; or

  • by using the 🖱 Right-Click Context-menu Delete action within the Visual View;

Deleting Connections (Disconnecting Eaves & Walls)

A Eave can be Disconnected (i.e. it’s Connection is Deleted) from a Wall through several means including:

  • Selecting the Connection Line between the Eave& Wall (shown in the Visual View when a Wall or Eave is 🖱 [Hovered]or selected & pressing the ⌨ Delete

  • Selecting the Connected Wall Row within the Eave Data-Grid & pressing ⌨ Delete


Moving

Eaves 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 an Eave or Eave Point in a straight Vertical or Horizontal direction by holding ⌨ Shift.


Parallel View of the Eave

Eaves are modelled within the Chenath Simulation as a Horizontal Shade object Parallel to the Connected Wall. The Projection Distance of the Eave from the Wall is based on the Parallel Distance between the Centre of the Wall & the Centre of the Eave.

Therefore Eaves 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).
