Overwriting Layer Geometry

When uploading to a Finch variant, everything already within the variant will be overwritten with the new geometry. You will get a warning before uploading to a variant that is not empty.

Geometry Types

Finch accepts closed Revit masses- meaning anything that lives inside of the mass family. Multiple objects inside of one mass will be boolean unioned together, so Finch will view them as one building.

In order for Finch to read your masses correctly, draw all parts of your building in one mass, so that is unioned together upon upload. Masses that are not in the same mass group will not be unioned into one building, even if they are intersecting.

The Revit- Finch Connection

The Revit-Finch integration works differently from the Rhino integration. While the Rhino integration is a live continuous sync, the Revit integration is uni-directional- meaning that you upload an empty mass, generate and work with the interior in Finch, and once ready to move to the next stage, download a BIM model.

Changes made in Revit to the downloaded BIM model cannot be uploaded back to Finch- only empty masses are accepted. Thus it is advised to make any changes in Finch, and re-download the BIM model into Revit as needed.
