Inside the Workspace
What does Inspection Mode do in PDFDepth?Inspection Mode turns a PDF plan into a live punch list: drop task pins on the sheet, assign them, filter by status, and export the list to CSV or PDF.What is File Take-Off Mode in PDFDepth?File Take-Off Mode counts a symbol you box once across every sheet in a plan set and produces a master CSV for estimating.What is Invoicing Mode in PDFDepth?Invoicing Mode drafts invoices and estimates from a plain-language prompt or a template, tracks clients, payments and overdue balances, then locks the result into a branded PDF.What is Feelings Mode in PDFDepth?Feelings Mode is the playful side of the editor: roast a document, turn it into a fantasy certificate, stamp it APPROVED or FINAL_FINAL_v9, and share the result as a card.What are Full Screen Mode and the Share panel in PDFDepth?Full Screen Mode turns the workspace into a presentation view, and the Share panel sends the open PDF — whole, specific pages, or the current page as an image — to WhatsApp, Teams, SMS, LinkedIn, or email without uploading it anywhere.What is the Markup & Measure panel in PDFDepth?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.What is Canvas Mode in PDFDepth?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.What is Image Editing Mode in PDFDepth?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.What is Collaborate Mode in PDFDepth?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.How do I share a PDF as a tracked link with view 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.How do I save and restore PDF versions in PDFDepth?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.How do I add fillable form fields to a PDF in PDFDepth?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.How do I lift objects out of an image into separate editable layers?Magic Layer detects the distinct objects in a page image or placed picture, lifts each into its own draggable layer, and can reconstruct the background so moved objects leave a clean plate behind.Can I design a PDF online with a drag-and-drop editor?Design flyers, menus, certificates, resumes, and invoices directly as PDFs: a drag-and-drop canvas with a 180+ template library, brand kit, AI design, magic resize, and GIF export — and the output stays a fillable, shareable PDF.How do I edit images inside a PDF without a separate app?Image Editing Mode edits a placed image or the whole page in place: compress, upscale, resize, crop, convert, watermark tools that run locally, a Gemini-powered AI edit suite, Magic Layer object lifting, and a passport-photo maker.How do I understand an engineering sheet from a discipline I don't know?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.What do the modes in PDFDepth's right panel actually do?Inspection, Quality Check, TakeOff & RFI, Engineering Mode, Markup & Measure, Invoicing, Canvas, Image Editing, Collaborate, Feelings, Full Screen — what each mode is for, and who it's for.
Construction & Engineering
What is a quantity takeoff?A quantity takeoff measures and counts materials on construction drawings — LF, SF, CY, EA — so estimators can price a bid. Here is how it works.How do I find the scale of a PDF drawing?Check the title block or view notes for a callout like 1/8" = 1'-0" or 1:100 — or calibrate against a known dimension. Here is each method.How do I measure distances and areas on a PDF plan?Calibrate the scale, then click two points for a distance or trace a boundary for an area. Here is the full workflow, from calibration to Excel export.How do I convert a PDF drawing to CAD (DXF or DWG)?Extract the vector linework from a PDF to DXF or SVG for AutoCAD, Revit, and BIM tools. Scanned PDFs need vectorizing first — here is what to expect.What is AI plan review and what does it check?AI plan review reads drawings and specs, then flags missing dimensions, cross-sheet inconsistencies, and code conflicts — each with a sheet citation.How do I extract specifications, loads, and dimensions from engineering drawings?Pull design loads, material grades, member sizes, and key dimensions out of drawings and specs into a table — instead of retyping general notes.Can AI identify walls, rooms, and ducts on a PDF floor plan?Yes — element identification reads floor-plan geometry and labels to classify walls, rooms, doors, and ducts into a tagged inventory. Here is how.How do I export PDF measurements to Excel?Calibrate, measure, then export an .xlsx with one row per measurement — type, label, quantity, unit, and sheet — straight into your estimate.How do I find every address in a PDF and open it in Google Maps?An address scanner reads the PDF text layer, detects street addresses, and lists them with page numbers plus a one-click Google Maps link.How do I compare two revisions of a PDF drawing?Open both revisions in a synced split view, run a text diff on notes and schedules, or slipsheet-compare a whole set. Three methods, explained.What is QC Mode in PDFDepth?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.Can I draft and edit CAD geometry inside a PDF editor?PDFDepth runs a CAD-style command line on the drawing: LINE, PLINE, OFFSET, TRIM, ROTATE, HATCH, DXF export, DWG import, vector snapping — plus an AI operator that edits geometry from plain language.Can I capture BIM-style element data on a PDF plan?BIM Capture drops typed pins — doors, walls, suppliers, fire ratings — with parametric fields and photos, AI-prefilled from a snapshot, and exports the whole set as JSON.How do I slip-sheet a revised drawing and see what changed?Open the old revision, run Slipsheet Compare, and pick the new PDF: changed regions come back as dashed diff boxes on your sheet while the new revision opens beside it in a synced split view.What do Smart Trace, Smart Overlay, and predictive snapping do in PDFDepth?Smart Ortho Snap squares near-horizontal lines automatically, OSNAP clicks onto the drawing’s own linework, detected regions convert to measurements on click, and the cut tool lifts linework into recolorable overlays.How do I measure volume — cubic yards of concrete or excavation — on a PDF plan?The Volume tool multiplies a calibrated area boundary by the depth you enter — concrete, excavation, and fill quantified as cubic quantities that export to Excel with the rest of the takeoff.How do I manage a whole plan set — sheets, revisions, reviews — in one place?Projects hold your plan sheets in one dashboard: open any sheet as a tab, share it by link, aggregate task photos, track review findings per revision, and run set-wide jobs like scale sync and master takeoff.Can I open a Procore document directly in the PDF editor?Paste a Procore document URL and an access token; the import function downloads the PDF through a server proxy and opens it in the editor as a normal document.How do I put inspection form fields on the plan sheets themselves?Inspection Mode’s Forms panel defines your own fields — text, number, checkbox, dropdown — applied to every task pin you drop; AI Plan Review can check Florida DOT sets against the Standard Plans they cite.What is the best Bluebeam alternative for PDF markup and takeoff?Looking for a Bluebeam alternative? Compare a traditional desktop plan-markup suite with an AI-powered browser workspace for takeoff, review, and collaboration.What is PDF takeoff software and how does it work?How PDF takeoff software turns construction drawings into quantities — calibration, AI-assisted counting, measurement lists, and Excel export for estimating.What does construction plan review software actually check?Construction plan review software checks drawing sets for code compliance, missing dimensions, and conflicting callouts — with citations, QC stamps, and version history.How do you measure construction drawings digitally?Digital construction drawing measurement — calibrate the scale, snap to linework, measure distance/area/perimeter/volume, and verify every quantity on the sheet.How do you compare two versions of a construction drawing?Compare two versions of a construction drawing — synced side-by-side view, vector diff overlay that highlights every change, and slip-sheet revisions under existing markups.How do you convert a PDF to CAD?PDF to CAD conversion — extract vector geometry from a PDF drawing into DXF for CAD and BIM import, including vectorize-to-CAD, DWG import, and a CAD command line.What is a construction PDF editor?A construction PDF editor marks up plans, measures quantities, reviews sheets, manages forms and signatures, and shares tracked links — built for drawing workflows.What is a construction plan viewer?A construction plan viewer opens large drawing sets in the browser — continuous scroll, tab sets, split view, thumbnails, full-screen mode, and high-fidelity rendering.What is the best PDF editor for architects?A PDF editor for architects — presentation-quality markups, calibrated measurement, drawing comparison, PDF-to-DXF handoff, BIM pins, and collaborative review.What software do engineers use to mark up and measure PDF drawings?PDF software for engineering drawings — precision markup, calibrated measurement, section properties, engineering parameter extraction, dimensioning, and Excel export.How much does a bad takeoff actually cost a project?What published industry research says about rework, estimating errors, and RFIs — and why measurement accuracy on drawings is a financial problem, not a convenience one.How do you benchmark a PDF takeoff workflow for speed and accuracy?A reproducible protocol for timing and error-testing any takeoff workflow — same sheets, same quantities, controlled measurement — so you can compare tools on evidence, not demos.What are digital construction drawings?Digital construction drawings are plan sets read and worked on screen instead of paper — what that enables for measurement, markup, review, and sharing.What does AI do versus what does a human do in a modern 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.
AI & Documents
Can I ask a PDF questions with AI?Yes — chat-with-PDF tools index the document text and answer plain-language questions with page citations. Here is how it works and its limits.How do I summarize a long PDF?An AI summarizer reads the full text layer and returns a structured summary — key points, sections, and action items — for you to spot-check.What is AI annotation for PDFs?AI annotation reads a document and adds highlights, comments, and callouts on the passages that matter — so review starts from a marked-up draft.How do I turn a PDF into a mind map?An AI mind-map generator extracts a PDF’s topics, sub-topics, and relationships into an interactive branching diagram you can expand and share.How do I auto-fill a PDF form with AI?AI Form Fill maps your names, dates, addresses, and values into matching PDF form fields for review before saving. Fillable fields required.How do I edit text in a PDF without changing the font?Editors that rewrite text in place and match the original font, size, and spacing produce invisible edits; overlaid text boxes look pasted-on.How do I publish a PDF as a website?Publish-as-website tools convert PDF content into responsive HTML pages at a shareable link — fast, mobile-friendly, no download required.How does semantic search work in PDFDepth?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.
Legal & Compliance
How do I build a chronological timeline from a folder of PDFs?A timeline tool reads each PDF in a folder, extracts the relevant date and a short summary, sorts chronologically, and exports a CSV.How do I redact sensitive information from a PDF?True redaction deletes the underlying text and image data — not just a black box on top. Find the PII, redact permanently, strip metadata.How do I add a real digital signature to a PDF — not just a drawn squiggle?Import a .p12/.pfx certificate, sign with SHA-256 PKCS#7 cryptography in the browser, stamp a visible signature block with issuer and reason, and optionally lock the PDF against further edits.
PDF Basics
How do I make a scanned PDF searchable (OCR)?OCR recognizes characters in page images and adds an invisible text layer — making scanned PDFs searchable, selectable, and usable by AI tools.How do I convert a PDF to Word, PowerPoint, or Excel?The Import & Export menu converts the open PDF to .docx or .pptx through the conversion service, or exports detected tables to .xlsx — with page ranges and an option to bake markups in first.What kinds of designs can you make as a PDF?Fifteen designs people usually reach for a template tool to make — invoices, flyers, menus, certificates, business cards, social posts, proposals, merch — each mapped to the concrete steps that produce it in a free browser PDF editor.
