Today: PDF only. Drawings up to 50 MB upload via the browser using a presigned S3 URL — the file never passes through our servers.
Page navigation
Open a drawing to step through pages, zoom, and rotate. The viewer remembers your zoom level when switching between drawings.
Linking drawings to BOQ lines
From a BOQ line item, click Attach drawing to reference a specific page. The line then shows a small drawing badge; clicking it opens the viewer at that page.
Replacing a drawing
Upload the new revision with the same filename to replace; older revisions are kept in S3 versioning and can be restored by support.
