Finch 101: Upload walls from Revit

In this tutorial, you’ll learn how to upload walls from Revit into Finch.

This workflow is ideal if you’re:

  • Working with an existing building that already has cores and circulation defined

  • At a stage in your project where walls, elevators, and stairwells are already modeled in Revit

  • Looking to use Finch’s generative tools around existing geometry

1. Make sure your conceptual mass is uploaded

Before uploading walls, you’ll need to have uploaded your conceptual mass from Revit to Finch.

🔗 See the previous tutorial: Upload Conceptual Mass, Grids, and Levels from Revit to Finch

2. Prepare your walls in Revit

  1. Open your Revit model and navigate to the level where you’ve drawn your walls — for example, Level 0.

  2. Select the interior walls you want to upload.

    • These can include corridors, lift cores, and stairwells.

3. Upload story walls to Finch

  1. Open the Finch plugin in Revit.

  2. Choose Story Walls instead of Massing.

  3. Follow the on-screen instructions:

    • Confirm that you’ve selected the correct walls.

    • Click Upload Story Walls.

4. Review your upload details

A confirmation window will appear showing:

  • The number of walls being uploaded

  • Any height discrepancies between Revit and Finch

💡 Because your conceptual mass was already uploaded with mass floors, Finch will automatically match your story heights and levels from Revit.

Click Upload Story Walls to finalize the upload.

5. Verify your walls in Finch

  1. Jump into Finch and open the variant you uploaded to.

  2. Wait for the sync to complete.

  3. You’ll see your walls correctly positioned inside your Finch model.

Now you can:

  • Assign programs and circulation spaces

  • Define space types like elevators and stairwells

  • Start generating unit mixes around your existing walls
