When we are working in Schematics, we have to build the geometry using Massing tab from the Design Bar. The Massing tab provides commands for creating massing shapes.
-
Once we are finished with our model geometry with Massing, we can assign colors or materials to the geometry in the massing mode. Select the the geometry and click on Properties. Click on the button next to Material under Material and Finishes. Select the required material from the Material dialog box and click Ok twice.
-
Repeat the above procedure for all required mass components to assign material. Then Click on Finish Mass to get back into Project.
-
We use the faces of Mass geometry to create Revit Building elements such as walls, curtain walls, roofs and floors which comprise the major building shell. The mass faces are not converted to Revit elements, they remain in the project. We can turn their visibility off to view only the building.
-
To convert mass faces to walls, select Wall by Face command under Massing tab from the design bar. Select the required faces of the mass and click on Modify. To convert the mass faces into curtain system, click on Curtain System and select the required faces of the Mass. After selecting the faces click on Create System on the Options Bar. Here we can select both vertical and horizontal faces to create Curtain System where as we can select all non-horizontal faces for walls.
-
To create roofs from mass faces, select the top face of the mass, and when the cursor displays a plus sign, select the face so that it highlights in red. The cursor displays a plus or a minus sign, indicating that we are adding or subtracting faces to and from the selection.
-
To create floors from the mass, select the required mass and click on Floor Area Faces on the Options Bar. Select the required levels to create floors from the Floor Area Faces dialog box. Now click on Floor by Face command in the Massing tab from the Design Bar and select the levels. After selecting levels, click on create floors.
-
The same procedure applies to Sketch up imported model in either mass family or an in-place family.
-
We can see the converted Revit building Elements by turning off the mass visibility. The visibility of mass instances is controlled in two ways:
-
Using the Show Mass button on the View Tool bar. It controls the visibility of all mass instances in the project. If you click the button, all mass instances (both the mass form and floor area faces) are visible in all views, even if mass category visibility is turned off in the Visibility/Graphics settings.
-
Specifying view-specific mass category visibility. The view-specific setting determines if the mass prints, and if it is visible when the Show Mass button is not selected. To display mass in a view, click View menu Visibility/Graphics and on the Model Categories tab, select the Mass category. If Mass is selected, the subcategories Form and Floor Area Face can be controlled independently.
-
To print mass elements, be sure the Mass category visibility is turned on. Mass elements will not print or export if category visibility is turned off, even if the Show Mass command is active.
