Upload the calculations, a beam schedule or a marked-up drawing. We read the sizes, grades and spans off it and show you every line with the original wording beside it. Spans come through as drafts - a span is measured between supports, so it is never the cut length.
Text-layer PDFs are read instantly. A scan or an image-only drawing needs the slower route below. Nothing is stored on the server - the file is read and discarded.
