Version 1.5

September 2026

AutoMEP Version 1.5 sizes ducts and pipes from published tables and tells you which one it used, lets a Revit model gain components and tags it does not already have, adds Revit 2027, and delivers sheets and PDFs that are ready to look at.

What changed

  • Sizing from published tables: ask for a duct or a pipe by its load rather than its size, and AutoMEP works the size out instead of guessing at one. It covers supply and return duct, water supply pipe, sanitary drainage by fixture units and gradient, and roof and rainwater drainage, in whichever unit system your drawing already uses.Watch: How to Auto-Size Ductwork & Generate Schedules with AutoMEP
  • It says where the size came from: the notes on a finished job now carry a line reading "Sized with reference to", followed by the table that was consulted, so a size you are asked to check is a size you can trace. This names the reference used to choose a size, it does not say the installation complies with anything.
  • Revit models can gain components they do not contain: if a request needs a thermostat, a diffuser or a control valve your model has never had, AutoMEP loads the family first and then places it, including in-line accessories such as control dampers and control valves that sit inside a duct or pipe run rather than beside it.
  • Your own families: upload the families your office standardizes on under Settings, and AutoMEP places those instead of generic ones. They stay private to your account and you can delete them whenever you like.
  • Revit tagging: ask AutoMEP to tag ducts, pipes, air terminals or equipment and it places the tags with their values in them. If your model carries no tag family of that category, which most do not, it loads one first rather than reporting success over a model where nothing was actually tagged.
  • Revit 2027, and a clear answer for 2025: AutoMEP now runs Revit 2024, 2026 and 2027. AutoMEP can no longer run Revit 2025, so a 2025 model is offered a one-time upgrade to 2026, and that happens only if you agree to it. Nothing is changed behind your back, and declining costs you nothing.
  • A Revit job delivers a Revit model: your result downloads as the .rvt it actually is, with an exported DWG and a plotted PDF alongside it, and both your upload and your result preview in the browser without opening Revit. AutoMEP can also create a sheet in Revit and place a view on it.
  • Sheets and PDFs that are ready to look at: landscape sheets, a viewport framed to the drawing rather than to the paper so a floor plan is not floating in an empty box, lettering sized to be readable at the plotted scale, and the legend on a sheet of its own. Every sheet previews on the project page now, not just the first one.
  • Bigger jobs, and bigger drawings: the ceiling on how much a single job can do has been raised for both AutoCAD and Revit, and the drawing payload was cut down considerably. Files that used to come back as too large now run, so a drawing that was refused a while ago is worth another try.
  • Ask a question, get an answer: a takeoff, a count, or "what size is the duct serving room 214" now comes back as an answer. It used to fail as a job that made no changes, which was true and useless.
  • Extra jobs, without surprises: the Extra jobs setting in Settings works properly now, and it carries a hard monthly cap so a bill cannot run away from you. AutoMEP also tells you in the app when a card was declined, and a renewal restores your allowance as soon as the payment lands rather than an hour later.
  • Dark mode and a simpler sign-in: AutoMEP follows your system theme, and signing in is one form now rather than a choice you have to make before you can type anything.
