Supported models and linking

This version accepts the element-based HTML format used by your model. The HTML must contain a JSON model array, with each element's ID, tag, positions and normals. You can also upload that array as a JSON file. IFC, GLB and Revit files must first be converted to this format.

The XER must contain a TASK table with planned start and finish dates. Activities are matched by the Element ID: in the activity name, then by an exact element tag or activity code. A link sheet overrides these for the elements it lists; the downloaded element links CSV can be edited and uploaded as one. Structure, architecture and MEP are recognized from the tags.

Progress uses elapsed planned duration and element count. It does not represent reported site progress.
