Workflow Advice for Using Tally with Revit 2025?

LCA Data & Tools

Hi everyone,

We’re running into an issue trying to use Tally for LCA on a project developed in Revit 2025. Since Tally is only compatible with Revit 2024 and earlier, we tried downgrading the model to 2024, but in doing so, we’re seeing a significant loss of assembly data—especially material layer information, which is critical for accurate LCA results in Tally.

Before we commit to manually rebuilding portions of the model, I wanted to ask:

  1. Has anyone found a reliable workaround for using Tally with Revit 2025 models?
  2. Is there a method to preserve material layer data during the downgrade process?
  3. Has anyone heard updates on Tally 2.0 and whether it might address this compatibility issue?

Thanks in advance!
Maggie
