Massing Model
|
Site Planning |
The Massing Model tool creates a building shell for illustrative purposes. This is an easy way to create a representative or context building when a detailed building is not required. Building models can also be created by drawing a closed 2D shape and then selecting the Create Objects from Shapes command (see Creating objects from shapes). A massing model can be a site modifier.
To create a massing model:
Click the tool.
The Massing Model tool and Campanile tool share the same position on the tool set. Click and hold the mouse on the visible tool to open the Pop-out tools list and select the desired tool.
Click to begin drawing the outline of the building. Continue clicking to draw the shell polyline. Double-click, or click once at the start point, to end the polyline. The first time you use the tool in a file, a properties dialog box opens. Set the default parameters. The parameters can be edited later from the Object Info palette.

Parameter |
Description |
|
Name |
Enter a building name for labeling |
|
Show in Plan |
Select whether to show the building roof or footprint in Plan view |
|
Label |
Select a text label, if any, for the building shell in Plan view; move the text control point to reposition the text
|
|
Height |
Specifies the building height (to the eave) |
|
Floor Count |
Specifies the number of floors in the building |
|
Opens the Floor Usage Data dialog box, for reporting the usage of massing model floors. This is useful in worksheets, for example, when reporting the usage data of the floors using the 'FloorUsageData' parameter (see Worksheet functions). The number of floors listed depends on the Floor Count (if the Floor Count is reduced later, floor usage data will be lost). By default, each floor’s usage is "Unspecified." To specify the floor usage data, select each floor and enter the Usage Data for that floor. A semi-colon cannot be used in the usage data, because this is the delimiter for the FloorUsageData function. |
|
|
Wall Class |
To control appearance, select a class to use for wall style attributes from the list of classes present in the drawing, or create a new class |
|
Use Custom Roof from Profile |
Creates a custom roof. The first roof created by the object is used as the default custom roof; if the number of stories has changed, the height of the custom roof needs to be manually adjusted. |
|
Roof Overhang |
Specifies the distance the roof extends from the building |
|
Roof Thickness |
Indicates the roof thickness |
|
Roof Class |
To control appearance, select a class to use for hipped roof style attributes from the list of classes present in the drawing, or create a new class |
|
Pitched Roof |
Adds a roof to the building shell |
|
Eave Style |
Select an eave style from the list |

Roof Slope |
Specifies the roof pitch angle in degrees |
|
Draw Floors |
Draws floors in the building |
|
Slab Thickness |
Specifies the floor thickness |
|
Display Shadow in Plan View |
Displays a shadow based on the roof outline in Top/Plan view. Document-wide settings from the Plan Shadows pane on the Document Preferences dialog box are applied. Click Shadow Settings to open the Document Preferences dialog box to review and edit the settings (see Document preferences: Plan Shadows tab). |
|
Use Site Modifiers |
Adds a pad and grade limits to the base of the building and allows the building to modify the site model |
|
Use Grade Limits |
Uses grade limits to define the site modifier modification area |
|
Grade Limits Off. |
Sets the offset of the grade limits from the massing model |
|
Gross Area |
Displays the gross area value for all the floors |
|
Vertex parameters |
Edits the object vertices. See Editing vertex-based objects. |
If the massing model is used as a site modifier, the proposed site model requires updating. Select the site model and click Update from the Object Info palette.
