What's new in Cella PDF

  • Open and save where your firm keeps its drawings: Dropbox, OneDrive (with SharePoint) and Google Drive, with Open from Cloud…, Open Set from Cloud… and Save to Cloud….
  • Resubmittal Report: Compare Sets written up for the plan reviewer, with before-and-after pictures of every change and the review comments answered.
  • Send to Client…: a copy for someone outside the firm with only what you choose in it; internal notes, statuses, authors and left-out markups are taken out of the file, and the original is untouched.
  • Presentation: a full-screen meeting view with a laser pointer, the arrow keys between sheets and a sheet number typed to jump.
  • Check Set: a pre-issue report of callouts to missing sheets, duplicate and skipped sheet numbers, index gaps, revision triangles without a schedule entry and unresolved markups, each a click from its sheet; export it as a PDF, Excel or CSV.
  • Seal Set: a seal preset (seal and signature pictures, licensee, statement, placement, certificate) applied to the chosen sheets of a document or a whole folder set, each file signed digitally once, with a verification page.
