Free Tool to Compare Revit Models And Visualize The Differences

UPDATE: Metamorphosis Installer for Revit 2015, 2016, 2017, 2018

This is a very useful addin coded by Matt Mason during a recent Hackathon. Basically, it lets you take a Snapshot of a Revit file at a point in time and save that info to a small database file. It is not saving pure geometry, but a lightweight set of all the useful information about the model, including parameters. Then, when you get a new file, you run the Compare function to compare that snapshot against the current model. Very cool.

Installing Metamorphosis

  1. Clone or download from the Github page
  2. Copy the files to your ProgramData Revit addins folder
  3. Restart Revit

This is a great little addin, it works quickly and it has a definite application in the real world. Full credit to all those involved in building it.

And judging by the Github updates, it may be developing further in the future…
