Send a proposal from Revit back to Forma

Step-by-step guide

Taking advantage of the interoperability between Forma and Revit can enhance the design process. After sending a Forma proposal to Revit to develop design components, it can be sent back to update the proposal in Forma. This enables further analysis and measurement against project goals as the design progresses.

1. In Revit, open the Forma proposal.

2. Complete any necessary design changes.

In this example, the surrounding design components are hidden to create a clean view of the proposed buildings. Then, to simulate a typical workflow, the selected exterior walls of the tallest building are changed to Exterior Glazing, and the roof slope is changed for two of the structures.

To send the updated design back to Forma:

3. On the ribbon, select the Massing & Site tab.
4. In the Forma panel, select Update Proposal.
5. In the Update Forma Proposal dialog box, expand the drop-down.

Note: Selecting (none) synchronizes the whole model, and selecting Cover Sheet View or 3D sends specific elements for update.

6. In this case, select (3D).

7. Click Update.

A confirmation message specifies the elements that Forma will create and those it will convert to meshes.

8. Click Yes to load the proposal.
9. Open Forma.
10. In the Navigator, select the proposal that was just sent back from Revit—in this case, the Forma Revit link proposal.

On the canvas, notice that the two buildings without Revit changes remain Forma-native, meaning that the areas for these buildings can still be viewed in the right panel.

However, the buildings with Revit changes are now converted to mesh objects, and Forma is currently unable to calculate the areas for these buildings.

Note that these area numbers can be controlled in Revit. It is also possible to add or remove buildings in Revit, and those changes will be reflected in Forma.
