Is my IFC file uploaded anywhere?
No. The file is read by your browser and parsed on your own machine with WebAssembly. It is never sent to Anvil or any other server — which is also why it works on a model you are not allowed to share.

Free IFC viewer
Drop an IFC file and look at the model. Members are coloured by type and a Z-up model is stood upright for you. It runs entirely in your browser — the file is never uploaded, so it works on a model you are not allowed to send anywhere.

Questions
Why does my model load lying on its side?
IFC is authored Z-up and 3D viewers are Y-up, so an unconverted model appears rotated 90 degrees. Stand it upright is on by default and applies exactly that correction; switch it off to see the model as authored.
What do the colours mean?
Members are grouped by IFC type — beams, columns, plates, fasteners, slabs, stairs and railings. Anything that does not resolve to one of those is grouped as Other rather than being silently recoloured into a category it does not belong to.
How large a file can it handle?
It is limited by your own machine memory rather than by an upload cap. Past roughly 150 MB the viewer warns you, because browser parsing becomes unreliable rather than merely slow.
Working from this model?
Anvil connects the model to the takeoff, the hours and the estimate.
