Compare the models inside the Revit

The possibility to compare and detect new, changed and deleted elements is divided into three different scripts.

The first file “01 Old model” you need to run when you open the old model. The purpose of this script is to collect all relevant data from the old model and to export that data to an excel file. When this script completes the work, you need to open a new model and run the file “02 new model”. This script will import the data from the Excel file and compare all data with the data of elements in the current (new) model.

Finally, if you want to see deleted elements. After you finish with the previous script. You need to open the old model and run the script with the name “03 Mark deleted elements”.

Please make sure that before you start using this script that you back up your existing project model.

Also, if you want to download this (and all other scripts) with my sample files please visit the Shop page.

The script uses the following Dynamo packages:

MEPover v.2019.12.1
BumbleBee v.2021.25.3
RIE v.2020.8.12
archilab v.2021.25.4
Clockwork v.2.3.0
ExcelReader v.134.1.1
