Holes

A Hole is the name Hero gives to Horizontal Openings between two Zones. The most common application for using Holes within a Project is to model a Stairwell opening between two Zones. The addition of a Hole between these two Zones ensures that the airflow & ventilation effects of this opening are accounted for in the Simulation.

Creation

Holes are created using the Hole Drawing mode (Skylight & Hole Drawing Mode).

Holes are created on the parent Floor that they penetrate (ie not on Ceilings), and must have an adjacent Zone below them, otherwise an Alert message will be raised and Simulation will not be able to proceed. An Alert will also be raised if a Hole is entered on a Floor with a Zone from a different Dwelling below it, Holes can only be modelled between Zones of the same Dwelling.  

Selecting

Holes are shown on the visual view and can be selected. Holes are added to the Floor Data-Grid as a child row under the Parent Floor and can be likewise selected there.

The Visual View’s Select Parent context-menu action for a Hole (or double-click mouse shortcut) will select the Parent Floor of the Hole.

Deleting

Holes can be deleted as per normal model objects using the Delete keyboard shortcut, or right-click context-menu action Delete or via the Data-Grid’s delete button. Points can be deleted off the Hole polygon shape by right clicking the Point and selecting Delete Point.

 Walls can be deleted by:

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

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

• by 🖱 Right-Clicking a Wall Point & choosing the Delete Point action.

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.

You can move a Hole or a Hole Point in a straight ↔ or ↕ direction by holding ⌨ Shift.

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.

Adding Points:

Points can be added to a Hole by right-clicking the Hole near it’s edge and selecting the Add Point Context Menu action.

Moving:

Holes can be moved either entirely by selecting the hole and dragging it while holding the left mouse button, or by left click & dragging individual points. The hole must remain within it’s parent floor during the move action.
