Polygon Rooms with Flat Ceilings

Polygon-shaped rooms with flat ceilings are created in Plan view and are characterized by a user-defined perimeter. Their walls may be angled or curved, if desired.

1. From the Add menu select Room - Polygon - Flat, or from the Rooms/Objects Toolkit select .
2. Specify a unique label for the room up to 32 characters long. The default label will be Room_1. Unless changed, subsequent labels will be Room_2, Room_3, etc. If a number is used for the label, subsequent labels will be incremented accordingly.
3. If desired, a description may be entered, up to 80 characters long. Meaningful descriptions including size and color will be useful for schedules.
4. The room will be created in AGi32 using the selected Wire Frame Color. This color is not used in AGi32's render mode, it is only used to represent the room's shape in the graphics window. By default, this color is green. To change it, click in the color cell. The Color dialog will appear for your use.
5. If surface labeling is desired, click on the Labeling button. A separate dialog will appear for specification of text labels for the room and/or its surfaces.
6. Enter the height of the room walls in the Wall Height text box.
7. All of the surfaces within the room are assigned a color. By default, the colors are made up of varying shades of gray corresponding to reflectance values of 0.8 (ceiling), 0.5 (walls) and 0.2 (floor)You may change the Reflectance by simply typing a new value in the Reflectance cell for the Ceiling, Walls or Floor. You may change the surface colors and their corresponding reflectances by clicking in the Color cell for the Ceiling, Walls or Floor. The Color Selection dialog will appear allowing you to select surface colors based on user defined reflectances.
8. You may assign a texture to the surface by clicking in the Texture cell. The Select Texture dialog will appear so that you may choose a texture from the Textures database. Alternately, you may browse for a texture anywhere on your system or assign a texture already in use on another surface in the job file. Once the desired texture is selected, you'll determine how the texture should be applied to the surface. Textures may be stretched across the entire surface, applied in a grid pattern or assigned a Static size (representing real dimensions) and tiled on the surface accordingly. In addition, you may opt to rotate the texture on the surface.

To delete a texture from the surface, Ctrl-click in the Texture cell and select the Delete key on your keyboard. When a texture is deleted from a surface, its correlated color and reflectance are used as the current color and reflectance.

9. Creation Method: Choose whether to manually create the boundary lines of the polygon or choose existing drawing entities as the boundary line.
• If a tilted line is selected, the room will be projected down to and created at lowest Z coordinate elevation.
10. Additional Tasks:
    • Specify Specify Calculation Points (selected by default): After clicking OK, the Automatic Placement dialog will open, with the workplane selected for the calculation grid. You may change any settings and then click OK. You will be returned to the graphics window, where you can draw the room (see Step 11).
    • Automatically Create LPD Area (not selected by default): If selected, an LPD Area will automatically be created, using the settings in the LPD/UWLR dialog. Exception: Creating an LPD Area this way sets the line color of the LPD Area to be the same as that of the Room for which it is being created. Clicking the Settings button opens the LPD/UWLR dialog, where you may set your preferences for this LPD Area.
11. Click OK to create the room. Follow the steps below depending on the selected creation method:

Specify a Polygon Manually

Create Polygon from Drawing Entities

To change the polygon elevation, move the cursor into the Z-Coord text box (before clicking the first point) and enter a new value or use the up and down arrow keys on the keyboard. Note: If the Z-Coord value is not equal to zero,a warning icon will be displayed to alert the user to this condition. Locate the first point of the polygon and click the left mouse button. Move the cursor to the second vertex on the polygon and left click again. You may specify an arc at the end of the current vertex by pressing the F4 key on your keyboard. Locate the second endpoint of the arc and left click again. By default, arcs are created in the counterclockwise direction, but their direction can be changed by pressing the F5 key. Specify the arc's radius by dragging the cursor and left clicking the mouse button. The object line will be attached to the arc's endpoint. Continue in this fashion until the polygon is complete. Right click to close the polygon shape. The Polygon room will be created.

Locate the pickbox on the drawing entity line you wish to use and left click. If a valid polygon is found (see Notes below), it will be displayed as a bold line, and the Polygon Search results dialog will appear: Accept Polygon and Repeat - Select another polygon line as a template for another room with the same properties. Use pickbox to select another closed polygon. Accept Polygon - Create room using selected entity as polygon boundary. Reselect Entities - Choose this option if invalid polygon was found or if incorrect line was chosen. Use pickbox to select another closed polygon. Manually Specify Polygon - Select vertices manually to specify polygon boundary, right clicking once all vertices are specified. This option is necessary if no valid polygon is found. Cancel - Do not create room. Notes: Drawing Entity line segments do not need to be joined, just need to be within tolerances (2 decimals of precision - .05) Line segments do not need to make a closed polygon - AGi32 will automatically close boundary line AGi32 filters related lines by color. Caveats: Disconnected line segments or line segments disconnected by gap larger than tolerance level will not form valid polygon. Polygons with intersecting lines will not form valid polygon. Incomplete polygons are not valid and may close in an unacceptable manner.

Notes:

• Important: By default, Rooms are composed of single-sided surfaces, facing inward. This attribute allows you to see into the room without having to walk inside in Render mode. You may flip the surface direction or change the surface type to two-sided in the Surface Edit command as well. Important: See Adding Rooms - Concepts (first section) for effect of single-sided surfaces on calculations.
• To apply additional surface properties (such as Texture, Transmittance, Transparency, Luminance, Specularity, Color Bleed control or surface specific Mesh Levels) to any of the object surfaces, you must first position the room in the environment. Then, either Edit the room and select the Surface Edit button in the Edit dialog or use the Surface Edit command to select the object.
• Removing Surfaces: Removing surfaces allows you to append other surfaces to factory defined shapes and create more complex models. Surfaces may be removed by Editing the room or using the Surface Edit command once it has been placed.
