Editable links and files
An editable URL fragment contains your complete current lumber list, including part names, sizes, counts and allowances. Anyone receiving it can read or modify an independent copy. The fragment may remain in browser history or be copied by other applications.
CSV and JSON always contain the complete list. Image/PDF disclosure checkboxes control those rendered outputs only. Review files and links before sharing confidential project information.
