Free Your Transmittals
If you’ve spent any time in the AEC industry, you already know the frustration. A revision gets issued, and suddenly someone’s manually copying sheet numbers into a spreadsheet, rebuilding the same transmittal document for the hundredth time, hunting down the distribution list, and hoping the file isn’t already open in Excel. It’s slow, it’s annoying, and depending on what your firm is paying for, you’re probably being charged for the privilege of a tool doing it for you.
Which is kind of insane when you think about it.
pyTransmit is a free, open source pyRevit plugin that takes care of the whole transmittal workflow from inside Revit. No subscription, no license fee, no company sitting between you and a basic part of your job. Just the tool, doing the work.
What it does
You open pyTransmit, you get a clean panel right there in Revit, pick your revision, set your reason, method, format, and print size, choose how to group the sheet list by whatever makes sense for the project, fill in who’s getting it, and that’s pretty much it. One window, one click, done.
Outcomes a properly formatted Excel workbook. Full header on page one with your project info, company logo, distribution list, and revision legend, clean pagination after that, print settings already configured for A4. If the file happens to be open in Excel already, no problem, it will tell you that. There’s a tab for the current issue and one for the full history, so you’ve always got a clean record of what went out and to whom.
Rather keep it inside the model? pyTransmit can push the transmittal tables straight into a drafting view in Revit, ready to drop onto a sheet or title block whenever you need it. It also exports a formatted revision schedule pulling live data straight from your Revit project, and if you just need a quick reference, there’s a revision legend export too. All without leaving Revit.
Works the way your office works
No two AEC firms run things the same way, and pyTransmit doesn’t try to force you into a box. You can set which fields show up, manage your distribution and client lists, and configure your own dropdown options for reason, method, and format. The settings system lets you point pyTransmit at a shared network location so every user on the team pulls from the same source automatically. Set it up once and any updates you make are picked up by everyone the next time they open the tool. No manual setup, no chasing people to sync their copy, it just handles it.
It’s going places
The tool is already wired into Revit’s live project data, and the groundwork is there for a fully integrated issuing workflow built right inside Revit. What’s here now is genuinely useful on its own, but this is still just the beginning.
Free, open source, no catch
Transmittals are just part of the job. They always have been. They’re not a premium feature and they shouldn’t come with a pricetag attached. pyTransmit exists because that situation was overdue for fixing.
Take it, use it, make it your own. You’ve paid enough already.
