TrueDim

TrueDim is the measurement-grade PDF markup app for people who work from drawings. Most PDF tools treat a sheet like a page of text. TrueDim treats it like what it is — linework at a scale, with a job riding on the numbers. DIMENSIONS WITH A SPINE • Witness legs with per-leg trims, five cap styles, and endpoint tags (VIF, AFF, CL and friends) • Multi-reading dimensions with a live readings table • Stable D-numbers and a dimension schedule that jumps to any dim on the sheet VERIFY AGAINST THE SHEET • Tap a printed scale note to adopt it • Tap a printed dimension to capture it as a live dimension • No text layer? Calibrate with two snapped clicks and a known length SNAPS TO THE REAL LINEWORK • Endpoints, intersections, and perpendicular tracking are read from the sheet's own vector geometry — the mark lands where the line actually is CHECK SETS THAT ROUTE THEMSELVES • Identity-locked ink for every reviewer • Move a set on and the work orders on that drawing follow the routing • Email notifications and the in-app Check Sets inbox keep the review moving without paper on anyone's desk ONE FILE, EVERY DEVICE • Marks live inside the PDF itself — a sheet marked on iPad opens live and editable on the desktop apps, and back again • Apple Handoff: an open review follows you between your devices THE ORIGINAL STAYS PRISTINE • Autosave writes to a verified working copy; the pristine sheet is never rewritten • Export flattened for the record, editable for the next reviewer, or clean Full markup kit: pen, highlighter, regions, polylines, polygons, clouds, callouts, text, photos, stamps, counts, and areas — with per-tool remembered styles and undo/redo everywhere. Core drawing and measuring works entirely on your device, with nothing to sign up for. Check-set pairing is an internal workflow for Fetzer Architectural Woodwork teams. Built by Fetzer Architectural Woodwork — for people who build from drawings, and for anyone who needs the number on the sheet to be the number in the field.
