TrueDim is the measurement-grade PDF markup app for people who work from drawings. REQUIRES A FETZER WORK ACCOUNT TrueDim is the field and shop tool for Fetzer Architectural Woodwork. Signing in with a Fetzer work email is required to use the app. Accounts are issued by the company ā there is no public sign-up, and the app cannot be used without one. Most PDF tools treat a sheet like a page of text. TrueDim treats it like what it is ā 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 ā 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 ā 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 ā with per-tool remembered styles and undo/redo everywhere. YOUR DRAWINGS STAY ON YOUR DEVICE Once you have signed in on a device, drawing and measuring keep working with no network. Your documents and marks are stored on the device; signing in carries only your name and work email. Built by Fetzer Architectural Woodwork ā for people who build from drawings.
