ARCA — Online 3D Spatial Viewer

Online Conversion Unavailable

BIM-to-GIS spatial conversion is computationally intensive and currently runs exclusively in your local environment.

Private & Local: No model geometry or proprietary architectural data is uploaded to remote servers.

High Performance: Uses native Python C-extensions (Shapely, pyproj, OpenSKP) for rapid mesh processing.

Interactive CLI & Studio: Run arca run model.ifc or launch local studio with arca serve.
