Creating a Massing Model

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 polyline and then selecting the Objects from Polyline command (see Creating Objects from Polylines). A massing model can be a site modifier.

 

To create a building model:

1.	Click the Massing Model tool from the Site Planning tool set.

2.	In Top/Plan view, 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.

3.	The massing model parameters can be edited in 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)
NumFloors	Specifies the number of floors in the building
Wall Class	Select a class to use for wall style attributes
Roof Overhang	Specifies the distance the roof extends from the building
Roof Thickness	Indicates the roof thickness
Roof Class	Select a class to use for hipped roof style attributes
Pitched Roof	Select to add 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	Select to draw floors in the building
Slab Thickness	Specifies the floor thickness
Use Site Modifiers	Adds a pad and control fence to the base of the building and allows the building to modify the site model
Gross Area	Displays the gross area value for all the floors
Polyline parameters	Edits the object vertices. See Reshaping Objects

4.	If the massing model is used as a site modifier, the proposed DTM requires updating. Select the site model and click Update from the Object Info palette.
