Room tab
The room tab is active when a case is first opened (afresh or from a wizard).
Rooms can be either shoebox shaped, prismatic or have a locked arbitrary geometry that has been imported. In the Room tab, you describe the typical rooms of the building. Typical rooms are rooms that are expected to have different indoor climate or service systems. For example, if an office building has many identical rooms facing south, it’s sufficient to model a single one of these rooms. In a smaller building all rooms might be described individually.
Figure 2.
Objects in the palette to the left on the screen can be used to replace the default objects in a room. Some objects, such as windows and doors, are inserted directly into the 3D view by dragging them. HVAC system objects and settings are dragged directly into the corresponding place in the form. Most of the default objects can either be removed, e.g. remove the default generic cooler to study a room without cooling, or replaced with other objects with different properties. The generic objects that are described in this help text are always available. In addition to these, there may be objects that represent products of given manufacturers. There may also be combination objects that fulfil more than a single function, for example a four-pipe fan coil that can both heat and cool the room.
Rooms table
At the bottom of the Room tab there is a Rooms summary table. All rooms of the building are shown in the table and key figures of the rooms are displayed. The floor area and the room multiplier can be edited. When either one of these are changed, the other figures of the room are updated. The building totals are shown at the bottom of the table. A target row is displayed at the bottom of the table where the actual building key totals can be entered for easy reference. When a room is selected in the table, its geometry and other properties of the room are displayed.
New room Click here to add a new room.
Import or Import > Room geometry… Add a new room by importing an arbitrary polygon-based geometry. The imported geometry will be un-editable.
Import > Room templates from IFC… Add new room templates by importing them from IFC, see IFC import below.
Duplicate To add a copy of a room, select it, and click “Duplicate”.
Remove To remove a room, selected it and click “Remove”..
Expand table Click here and the Rooms summary table is opened in a separate resizable window for easy viewing of a larger number of typical rooms.
3D view
In the 3D view you can rotate, pan, zoom and move an object. How to do this is explained below. Pointing with the mouse on the “Help for 3D view” will display a text about mouse operations in the 3D view as a tooltip, and in a dialog when the button is clicked:
To Select an object: click on the object with the left mouse button. The selected object is shown in red.
To Rotate the model: press down the left mouse button on the object and move the mouse.
To Pan the model: use the middle mouse button (or both the left and the right mouse buttons on a two button mouse): Press down and move the mouse left, right, up or down.
To Zoom the model: press down the right mouse button: Move the mouse upwards to zoom in and downwards to zoom out.
To zoom out to Zoom extents: click with the right mouse button in the 3D-vew and choose “Zoom extents”. This will move the model so that the entire model is visible.
To Open the dialog for a window, door or a surface part: Click with the right mouse button on the object and choose “Open” in the menu.
To Set focus in the 3D view: Click with the right mouse button in the 3D view on the spot where you want the focus to be and choose “Set focus”. This sets the point around which the model is rotated and towards which it is zoomed.
To move a room in the z-direction, select the room and press the Ctrl-key and the Shift-key and move the room with the mouse. (Only possible when entering the 3D view via the Building tab).
To Drag a window, door or a surface: select the object, press the Ctrl-key and move the mouse pointer.
To create a Section view of a room or a model:
the x+, x-, y+, y-, z+, z- buttons create a section through the room. When section is activated, press Ctrl-key, click within the red frame and move the mouse pointer, to move the section.
x+ Cut the 3D model along the x-axis removing all geometry on the positive side of the cut plane.
x- Cut the 3D model along the x-axis removing all geometry on the negative side of the cut plane.
y+ Cut the 3D model along the y-axis removing all geometry on the positive side of the cut plane.
y- Cut the 3D model along the y-axis removing all geometry on the negative side of the cut plane.
z+ Cut the 3D model along the z-axis removing all geometry on the positive side of the cut plane.
z- Cut the 3D model along the z-axis removing all geometry on the negative side of the cut plane.
Restore default view: Clicking here will zoom and pan the model so that the entire model is visible and undo any cut of the model.
