Screens

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 IN THE VISUAL VIEW

Creating

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

Attaching to Walls

Given that only 3 Screens are only able.

Walls must be Attached to Screens for their impacts to be modelled.

Selecting

You can Select a Ceiling Fan or Penetration within the Visual View. Penetrations can also be selected within the Data-Grid and this will be reflected 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.

Deleting

The Screen itself can be deleted by:

selecting the Screen 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

Moving

Zone Items can be moved in the Visual View by selecting them and then 🖱 Dragging them into their position.

Zone Items cannot move outside of the Zone

You can move a Zone Item in a straight ↔ or ↕ direction by holding ⌨ Shift.

Modelling Screens over Multiple Levels

Currently 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.

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).
