TrueDim
Measurement-grade markup
Free · Designed for iPad. Not verified for macOS.
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 — 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 — 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.
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 — for people who build from drawings.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Check sets that had been routed, cancelled or stepped into from Keel open again on iPad.
• A check set whose history holds Keel's routing notes no longer stops with a request to repair its ledger. Every real saved copy is still checked as strictly as before.
