Compare Revit and Forma designs
Compare analysis results between Forma and Revit designs in Forma using the Compare tool.
Step-by-step guide
Forma-Revit interoperability enables the comparison of analysis results for different versions of a proposal using the visual compare mode in Forma. For example, a side-by-side comparison of sun hours between a Revit design and a Forma design can be set up.
Begin with a Forma version and a Revit version of a proposal already created and open in Forma.
- If needed, run the desired analysis to be compared on each version.
- In this example, to run the analysis on the Revit version, in the Navigator, select the Forma Revit link proposal.
- In the right panel, select Sun hours.
- Click Run Analysis.
The analysis completes quickly.
- In the top bar, click Compare.
To select the items to compare:
- In this case, under the Forma Revit link proposal, expand the available analyses.
- Select Sun hours to add it to the left view.
- Expand the Forma version proposal and select Sun hours.
- Drag and drop the Sun hours analysis into the right view.
The designs display side-by-side.
- Rotate and zoom to see that both designs update accordingly.
In the analysis panel for each design, there are options for comparison. These specific analyses enable the selection of different dates and time intervals, as well as the comparison of direct sun on the ground.
To see analysis results for specific points on the design:
- Select Inspect, or press the keyboard shortcut I.
- Click specific locations on the canvas.
Notice that clicking in one view displays the corresponding sun hours for the selected points in both design views:
Adjustments can be made to change the content and appearance of the results displayed in the comparison.
To compare the geometry that receives between zero and two hours of sun daily using a top view:
- To filter the analysis bar for each view, click and drag the right handle from the edge of the analysis bar to 2 hours of sun.
The colors displayed in the designs update accordingly.
- In the visibility and orientation toolbar, select Camera position > Top View.
- Click Inspect to remove the inspection points.
The compare mode in Forma enables easy comparison of design analysis results that provide valuable insights for informed decision-making.
