Field notes
After a file is selected, the interface shows a staged pipeline: reading the file, loading the computation core on first use, triangulating the model, and analyzing geometry. Users can change quality from rough to very fine; the page warns that large assemblies may take a minute or more and suggests rough quality for speed. The controls also expose sectioning, axes, transparency, layers, and orthographic viewing.
