Mon, 12 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/right-panel-modes-guide https://pdfdepth.com/blog/engineering-mode-explainer Engineering Mode identifies the sheet's discipline, explains what that discipline does, and drops temporary callouts on the elements drawn — so a non-MEP person can still read an MEP sheet. Sun, 11 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/engineering-mode-explainer https://pdfdepth.com/blog/ai-vs-human-takeoff-workflow AI counts, searches, detects, compares, organizes, and runs first-pass measurement. Humans supply judgment, exceptions, ambiguous-drawing calls, final quantities, pricing, and scope decisions. Here is the split that actually works. Sat, 10 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/ai-vs-human-takeoff-workflow https://pdfdepth.com/blog/qc-mode QC Mode brings DOT-style quality control inside the plan set: a five-stage review stamp on page 1, enforced color-coded markups per stage, initials-and-date sign-offs, a live progress panel, and a share-for-review link — so multi-reviewer plan reviews stay documented and consistent. Tue, 06 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/qc-mode https://pdfdepth.com/blog/markup-and-measure Markup & Measure is the right-panel home for the measuring workflow: named style presets, the current page’s calibration and display unit, a per-page measurement list, and engineering properties for any closed shape. Tue, 06 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/markup-and-measure https://pdfdepth.com/blog/canvas-mode Canvas Mode turns the editor into a page-design workspace: insert text, images, shapes, tables, charts, QR codes, and form fields; style and arrange them; apply from a 170+ template library; set a brand kit; draft with AI; and resize for print or social. Tue, 06 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/canvas-mode https://pdfdepth.com/blog/image-editing-mode Image Editing Mode targets a placed image or the whole page: compress, upscale, resize, crop, convert format, remove watermarks, or add a text/logo mark — plus a Gemini-powered section for object-level edits. Tue, 06 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/image-editing-mode https://pdfdepth.com/blog/collaborate-mode Collaborate Mode gathers the teamwork features: pinned comment threads with assignees and due dates, named version snapshots, tracked smart links, and role-based access control on the shared document. Tue, 06 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/collaborate-mode https://pdfdepth.com/blog/smart-links-pdf-analytics Create a public link for the open PDF — optional password, expiry, email gate, and download/print controls — then see who viewed it, how long they stayed, and which pages held attention. Tue, 06 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/smart-links-pdf-analytics https://pdfdepth.com/blog/pdf-version-history Version History saves named snapshots of a cloud document — the PDF plus every annotation, measurement, calibration, and form field — so you can view an old revision in a new tab, restore it, or mark it approved. Tue, 06 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/pdf-version-history https://pdfdepth.com/blog/smart-forms The Smart Forms menu drops fillable fields — text, checkbox, radio, dropdown, date, signature, initials, file upload, number, email — onto the page; they export as real AcroForm widgets that stay fillable anywhere. Tue, 06 Oct 2026 00:00:00 GMT https://pdfdepth.com/blog/smart-forms https://pdfdepth.com/blog/semantic-search-pdf Flip the Semantic toggle in the Find panel and the first search builds a one-time embedding index of the document; results rank by meaning with a page and snippet, and clicking jumps straight to the line.
