A Hole is the name Hero gives to horizontal openings Horizontal Openings between two zonesZones. The most common application for using Holes within a Project is to model a stairwell Stairwell or similaropening between two zonesZones.
The addition of a hole Hole between these the two zones Zones ensures that the airflow Airflow & ventilation Ventilation effects of this opening are accounted for in the simulation.Creation: Simulation.

Holes vs Void Zones - When to UseHoles are used to connect two different Zones through a ventilation opening (typically via a Stairwell or similar). A Void Zone Type (see Zones) is used to model the upper portion of a single Zone that projects over two Levels. |

HOLES WITHIN THE VISUAL VIEW
Creation
Holes are created using the Hole Drawing mode , which is detailed in a further section of this tutorial series. They (Skylight & Hole Drawing Mode).
Holes are created on the parent Floor that they penetrate (ie i.e. not on Ceilings), and must have an adjacent zone Adjacent Zone below them, otherwise an alert Alert message will be raised and simulation Simulation will not be able to proceed. An alert Alert will also be raised if a Hole is entered on a Floor with a Zone from another dwelling a different Dwelling below it, as holes Holes can only be modelled between zones Zones of the same dwellingDwelling.
Selecting
...
Holes are shown on the visual view Visual View and can be selected as per normal objects. Holes are added to the Floor Data-Grid as a child row under the Parent Floor and can be likewise selected there.
The You can also use the Visual View’s Select Parent context-menu action for a Hole (or double-click it’s 🖱 Double Left-Click mouse shortcut) will select the Parent . In this case, the action selects the parent Floor of the Hole.
Deleting
...
Holes can be deleted Deleted as per normal model objects using the ⌨ Delete keyboard shortcut, or right-click context🖱 Right-Click Context-menu action Delete or via the Data-Grid’s delete Delete button. Points can be deleted off the Hole polygon shape by right clicking 🖱 Right-Clicking the Point and selecting Delete Point.
Geometry:
Area:
The hole’s area is the main property of a hole that effects simulation, and can be seen within the Area column of the Floor data-grid tab.
...
Moving Holes
Holes can be moved in the Visual View by selecting them and then 🖱 Dragging them into their position.
You can also 🖱 Drag the Points of a Hole to move that Point and extend or shrink the length.
| Note |
|---|
Holes cannot be moved outside the bounds of the Zone |
You can move a Hole or a Hole Point in a straight ↔ or ↕ direction by holding ⌨ Shift.
Adding Points
Points can be added to a Hole by right🖱 Right-clicking the Hole near it’s edge and selecting the Add PointContext Menu action.
