Bose ® Modeler ® Software User GuideChapter 6: Modeling WorkshopBefore you get startedThis chapter is a step by step guide to creating the First StreetChurch model that is referenced throughout the user guide.Before you get started, create a new project and a new model.Follow these steps to create a new project and model:1. Launch Modeler software.2. Choose File > New Project.3. Name the new project “Workshop” and navigate to an appropriatefolder to save the project in, or just choose the desktop. ClickSave.4. When the New Project window opens, choose New to create anew model.5. Name your new model “Workshop Model” and click OK.There are a few steps you should always undertake before youcreate a model: You should set the Modeler software preferences,and select the materials you will use to build your model in theMaterial Database.Setting Modeler software preferencesYou have the ability to specify how numerous features in Modelersoftware will act based on the requirements of your project. In thissection, you will set the preferences for the workshop model.Chapter 6: Modeling Workshop 99

Bose ® Modeler ® Software User GuideFollow these steps to set the preferences for the modelingworkshop:1. Click Edit > Preferences, or press Ctrl + R. The Preferencesdialog box opens with the Drawing tab selected by default.Figure 6.1 - Preferences dialog box2. Make the following changes in the Drawing tab:• Under Snap To Vertex, make sure there is a checkmarknext to Enable, and change the value under the checkboxfrom 0.5 m to 1.0 m. This causes surface vertices to snapto the nearest other vertex if the two are less than 1 mapart.• Under Room Snap Grid, make sure the sensitivity is setto 0.5 m. This means that all objects will snap to halfmeter subdivisions of the grid.100 Chapter 6: Modeling Workshop

Bose ® Modeler ® Software User Guide• Make sure there is a checkmark in all the checkboxesunder Selection.Tip:In a complicated or cluttered model the Selection groupcheckboxes allow you to specify the type of object you want toselect with the mouse. You can remove the check mark from typesof objects that you do not want to select with the mouse.• Under Curved Surfaces, enter a value of 30º for theAngular Increment. Curved surfaces in Modeler softwareare simulated as numerous flat surfaces joined together toform a curve. Under Curved Surfaces you specify theangular increment that is used to draw the curve. At eachangular increment, a new surface is created, so theangular increment dictates how many flat surfaces areused to simulate the curved surface.3. Select the View tab and make the following changes:• Under RT60, click the Size dropdown menu and selectSmall. This reduces the display size of the purple sphererepresenting the location of the RT60 source.Note:The RT60 source represents the location where sound comes fromwhen measuring the reverberant decay curve for the room.• Under Surface, place a check mark next to Vertex. Thiswill highlight the vertices of each surface.4. Select the Acoustics tab and make the following changes. Hereyou can specify conditions that affect the room acoustics.• Enter 22 (ºC) in the Temperature field.• Enter 60 (%) in the Humidity field.• In the drop-down menu at the bottom of the BackgroundNoise section, select NC40. This selection representsminimal background noise.Leave the Preferences dialog box open and proceed to thenext section.Chapter 6: Modeling Workshop 101

Bose ® Modeler ® Software User GuideClosing the room modelYou have created all of the main surfaces of the model. There arestill a few open spaces which you will fill in with surfaces in thefollowing lessons. A model that has no open or missing surfaces iscalled a closed model.In order to close your room model, you will first create the wallsurfaces highlighted below. These are called adjoining walls.Figure 6.65 - Remaining wall surfacesDrawing the nave adjoining wallThe nave adjoining wall joins the nave alcove with the nave. Thissurface can be created using the Insert Face tool. The Insert Facetool allows you to create a surface by outlining the vertices thatmake up the perimeter of the shape.144 Chapter 6: Modeling Workshop

Bose ® Modeler ® Software User GuideFollow these steps to create the nave adjoining wall:1. Select the Rotate View tool (press the D key).Rotate the model until the view closely matches Figure 6.66.You will click on the vertices that outline the nave adjoiningwall, so it is important that you can see all the vertices. Zoomin using the Zoom tool if you need to.Figure 6.66 - A good viewing angle for creating the nave adjoining wall2. Select the Insert Face tool:Figure 6.67 - Insert Face tool3. To define the nave adjoining wall, click on the vertices that form itsperimeter. Each vertex will highlight in green when the cursor ismoved over it. The surface is completed when you click on thered dot indicating the starting point.Chapter 6: Modeling Workshop 145
