Parapet is a growing family of add-ins (plugins) for Autodesk Revit 2020-2027 made by an independent developer. Today it ships Parapet Hub (bulk parameter editing and 389 one-click actions), Parapet Link (Excel, CSV, JSON, XML and Google Sheets to Revit) and Parapet Audit (free: every external file, link and parameter in the model, checked and fixed). All apps install from one installer into one Parapet ribbon tab and share one license portal.

Is there a free trial?

Yes. Install Parapet, open the Parapet tab in Revit and click Licenses → Start free trial. You get the full product for 14 days, no card required and nothing converts automatically.

Will there be more Parapet apps?

Yes. Parapet is built as a platform: every new app drops into the same Parapet tab, the same installer and the same license portal. Three apps ship today.

Parapet

Add-ins for Autodesk Revit 2020-2027 · one tab · one installer · one license portal

Revit, minus the
repetitive parts. Three apps in one Parapet tab: Hub for elements and bulk parameters, Link for spreadsheets, and Audit - free - for everything your model secretly carries.

Every Parapet app started as something a Revit user did 400 times by hand. Each one does that job end-to-end - with a dry run before every write, one Ctrl+Z after, and a report of what changed.

The Parapet Hub window inside Revit on a real project: 121 categories in the sidebar, 54 rooms loaded in the grid with numbers, names, levels and areas, and a ribbon of category tabs showing the room tools. — No mockups on this site - this is **Parapet Hub on a real model: 121 categories, one grid,** and a ribbon that has become the room tools. Link and Audit live one click away in the same tab.

389one-click actions in Hub

6formats in Link: Excel, CSV, JSON, XML, Sheets

92tools in Audit - the free one

1Ctrl+Z per action, always

A Friday afternoon in Revit: 1,247 warnings, a door schedule in its seventh version, a 912 MB model and 60 sheets due Monday. Each of those is a Parapet app.

The bulk edit

340 doors, 180 rooms, one parameter each.

The Properties palette edits one selection at a time; a schedule edits one category and validates nothing. So it gets done by hand, badly, twice.

Hub: pick → grid → Set value… → one undo. Or one of 389 actions.

The spreadsheet

Door_Schedule_FINAL_v7 (2).xlsx changed again.

Revit has no "import from Excel". Retyping invites typos; the Dynamo graph broke when its author left.

Link: every changed cell listed, push or pull with one undo.

The heavy model

Nobody knows why the file is 912 MB.

41 DWG imports, 9 nested in families, two point clouds nobody can see - and nothing in Revit that lists them.

Audit (free): every file found, graded, deleted safely. 412 → 168 MB is a real afternoon.

The apps, up close

Real windows on real projects - click through for the full tour of each. Install once; keep what earns its place.

Pro

Every element, every parameter, one grid - and a ribbon that becomes the tools for whatever you pick.

Pick by category → family → type, or start from your Revit selection - picks add up
Bulk-edit parameters: type, paste from Excel, or Set value… on every checked row - validated, one undo
389 one-click actions, each with a live dry run: renumber rooms, sheets from views, color by parameter, move to workset, connect open ends…
Save any sequence as a recipe - one button, one undo, exportable as JSON

See Hub →$99/yr · 14-day free trial

Parapet Link

Pro

Revit on one side, your spreadsheet on the other - every cell shows both values and which side is newer.

Start from Revit (export a scope that comes back in sync) or from any file: Excel, CSV, TSV, JSON, XML, Google Sheets
Columns match your parameters by name; map the rest by clicking their headers
Push, pull, resolve conflicts - a dry run under every button, one undo each
Rows are never added to the model silently; invalid cells go red before anything is written

See Link →$79/yr · 14-day free trial

Parapet Audit

Free

Everything your model imports, links or attaches - found in seconds, graded in plain English, fixed with one undo.

12 file kinds: CAD imports and links, Revit and IFC links, point clouds, images, PDFs, decals, keynotes - plus every project and shared parameter
34 checks per file - shared coordinates with the exact offset, nested links, far from origin - and a whole-model health pass
92 tools, all free: re-path every link at once, import → link, purge what Purge Unused skips
Share the audit as a link; Audit Pro adds the record - history, comparison, portfolio and the BIM QA Kit with a go / hold decision

See Audit →The add-in is free · Audit Pro $49/yr, included with Hub and Link

Built as a platform, not a plugin

One Parapet tab in the ribbon. Every app we add lands in it - same installer, same account, same rules.

Every Revit you run

The installer detects Revit 2020-2027 and installs for each. One key covers all versions - and the next release.

Licensing that stays out of the way

One key for everything (Parapet Pro) or one app at a time: free apps register silently, paid apps start a 14-day trial from inside Revit. Two computers, two weeks offline, move seats yourself.

Built on real projects

Every feature started as something a Revit user did 400 times by hand. Support replies come from the developer who wrote the code.

What Revit users fix with Parapet

Jobs that take an afternoon by hand and a minute with the right add-in.

Bulk-edit parameters across hundreds of elements

Pick doors, rooms or any category, show only the parameters you need, paste a block from Excel or set one value on everything - validated, one Revit undo.

Link Excel, CSV or Google Sheets to Revit

Room programmes, door schedules, equipment lists and classification codes maintained in a spreadsheet, pushed into the model without retyping.

Find what makes the model slow, and remove it

List every DWG import and link, see which views use it, delete the junk safely. Free.

Renumber rooms, create sheets from views, color by parameter…

389 one-click actions on a ribbon that follows what you pick - a tab for each category you tick (rooms, walls, doors and windows, floors, ceilings, roofs, stairs, ducts and pipes, furniture, site and more) plus Edit, View, Manage and Recipes.

By hand versus with Parapet - indicative timings from real projects.

Made for the people who open Revit at 8:00

Different desks, same afternoon.

Architects

Room numbers that follow the plan, door schedules that match the consultant's sheet, sheets that create themselves.

Which Revit versions does Parapet support?

Revit 2020, 2021, 2022, 2023, 2024, 2025, 2026 and 2027 on Windows 10/11. One installer, one key for all of them. Revit LT is not supported because it has no add-in API.

How much does Parapet cost?

The Parapet Audit add-in is free; Audit Pro adds the web-side history, comparison and BIM QA Kit for $49/year. Parapet Pro (Hub, Link and Audit Pro together) is $149/year; Hub alone is $99/year and Link alone $79/year. Every paid plan starts with a 14-day free trial, no card, and covers 2 computers. See pricing.

Does Parapet upload my Revit model?

No. Everything runs locally inside Revit. The only network traffic is the license check. Google Sheets data moves directly between your PC and Google under your own account. See privacy.
