Questions
Is Parapet Audit really free?
Yes. Free forever, no license key, no trial, no card, no feature limits. The first time you open it you register with your email (we send a 6-digit code to confirm it) - that is the whole sign-up. It ships in the same installer as Parapet Hub and Link.
Which file types does it find?
Everything Revit can import, link or attach: CAD imports and links (DWG, DXF, DGN, SAT, SKP, OBJ, STL, 3DM, FBX), Revit links including cloud models, IFC links, Navisworks coordination models (NWC, NWD), point clouds (RCP, RCS), raster images (PNG, JPG, BMP, TIF), PDF imports and links, decals, keynote tables, assembly code tables and DWF markups.
Does it work on large models?
Yes. The window opens instantly with the inventory. The view-by-view usage scan runs only when you ask, is read-only, and processes views in batches with a progress indicator, so a 400 MB model never freezes Revit.
Can it fix shared coordinates?
It checks them - every Revit and IFC link is compared with the host and you get the exact offset and rotation. Acquiring or publishing coordinates is not something Revit allows add-ins to do, so Audit selects the link and tells you which Manage Links command finishes the job.
The links moved to a new server. Can it fix them all at once?
Yes. Check the links, open Re-path, type the old root and the new root. The dry run lists every link with the path it would get and whether the file is there; nothing is reloaded until you confirm, and one undo reverts the lot.
Is it safe to delete files with it?
Every destructive tool shows a dry run first - the files, instances, ids and distances it will touch - and runs as a single Revit transaction. One Ctrl+Z reverts it. Nothing is touched on disk.
Does it remember previous audits?
Yes. The last 12 audits are stored inside the model itself, so whoever opens Audit next sees what changed since the last run - new or removed files, changed paths, links that went missing, files that moved - with a Changed filter to list only those. Nothing is uploaded anywhere.
Can I share the results with the team?
Yes, two ways. Share on parapet.app uploads the audit and gives you a link anyone can open in a browser - charts, every file with its checks, coordinates, nested links and the run history; the last 3 runs of each model are kept for free, every run with Audit Pro. Or save a self-contained Health report (HTML + CSV) and Copy table into Excel or an email.
What is Audit Pro?
The web side of Audit. Free sharing keeps the last 3 runs of each model and gives you the full report page by link. Audit Pro keeps every run, compares any two runs file by file, shows each file's history, exports CSV / JSON, adds notes and assignments, renames and merges models, makes audits private, shows where every placed file sits in 3D and gives you a portfolio dashboard. It costs $7/month or $59/year and is included with any Hub or Link subscription. Nothing to enter in Revit: Pro follows the email you registered Audit with. Get Audit Pro.
What leaves my computer when I share?
Only what the report shows: file names, kinds, paths (or just file names if you choose), checks, counts, coordinates, nested links and the dots of the placement map; with "Include 3D placement" ticked, also one bounding box and the position of each placed file, the model's overall box and its level heights. Never the model, its geometry or parameters. Sharing is off until you press Share, and you can delete a shared audit any time from parapet.app/audits.
Can it turn CAD layers off?
Yes. The Layers tab lists every layer of a CAD file with the curves, meshes and points it carries and whether it is hidden in your view. Hide layer turns one layer off in every view, only where the file shows, or only in the active view; Unused layers off turns off the layers that carry nothing. Views that take their visibility from a view template are changed through the template, and the dry run tells you which.
Can it turn an import into a link?
Yes, for DWG and DXF imports. Import → link asks where the file is, links it at the same position, scale and rotation as the import, keeps the pins, draw order, workset and the layers you had hidden, and deletes the import - one undo brings it back. DGN, SKP and SAT imports are re-linked by hand.
What does "Fix safe issues" do?
Only what cannot go wrong: pins unpinned files, sends CAD imports behind the model, switches absolute network paths to relative, and re-paths missing links when exactly one file of that name sits under the model's folder. The dry run lists all of it before you press the button, and it is one Revit undo.
Does it audit parameters too?
Yes. The Params segment lists every project and shared parameter in the model and every shared parameter that exists only in the shared parameter file - binding, data type, group, categories, how many elements carry a value, GUID, whether it is in the file. Nine checks catch the classics: project parameters that should be shared, shared parameters missing from the file, same name with a different GUID, nothing bound, nothing filled, duplicate names, stray spaces. Convert to shared turns a project parameter into a shared one with every value kept; Add to file, Bind, Categories, Binding & group, Rename and Unbind do the rest in bulk, each with a dry run and one undo.
Can it audit a whole project folder?
Yes. Audit a folder opens every model in a folder one by one - read-only, workshared models detached, never saved - audits it, closes it and writes one CSV with files, instances, issues, health and the top findings per model. Scheduled audit does the same for the model you are in, silently, every time it opens or after every sync.
Which Revit versions are supported?
Revit 2020, 2021, 2022, 2023, 2024, 2025, 2026 and 2027 on Windows 10 and 11. Per-user install, no admin rights required.
Does my model leave my computer?
No. Audit reads the open document through the Revit API and never uploads anything. The only thing we store is the email you register with - no model data, no file names, nothing from the project.
