The model check that will not line itself up

The startup idea

The problem

An AI-built MEP model can look right and still miss a run.

Who would pay for this?

Primary

A Revit user who already has pyRevit and a reference MEP model.

Secondary

A team that will pay KIDGE for the PDF instead of running the buttons.

Early adopter

One pair of models, same origin, the tolerances printed.

How could it make money?

Possible models. Nothing here is a claim about what Revit Model Compare charges.

• The extension is MIT and free.
• Reports and adoption support are a separate offer from KIDGE.
• The post says open source.

What would the MVP look like?

1. Export, then compare.
2. A shared origin required.
3. Fixed tolerances shown.
4. Issue shots on a copy.

How to validate the idea

• Ask five people to compare two models with different origins.
• If the tool moved one, it is no longer the readme.
• Do not treat a paid PDF as the open-source button.

How to differentiate

• It measures geometry, not a rendered picture.
• It refuses to align the models.
• The report service is optional.
• Do not become Revit.

Product that inspired this idea

Monica's post says a pyRevit tool compares two MEP models by geometry: coverage, missing, extra, moved, and wrong-size parts, plus screenshots. Open source. The reply links kidge-io/revit-model-compare. The readme says MIT, free, built by KIDGE Ltd. You need Revit, developed on 2024, and pyRevit. Both models must share the same internal origin. The tool does not align coordinates. Tolerances are fixed for now, 5 mm, 50 mm, and 1 m. Issue Shots should run on copies. It adds views and does not edit elements. Paid work sits beside the tool: KIDGE will run the comparison and deliver a report, or help a team adopt it. The post does not say the models have to share an origin, or that the report is a separate service. This page did not open Revit.
