Why do the Tridify BIM Tools work differently to the tutorial/video?

Make sure you get the latest version of the Tridify BIM Tools by logging in to Unity before downloading the asset. Otherwise, Unity will import the old version of the BIM Tools from the cache (Asset Store's Temp folder location in Windows is C:\Users\accountName\AppData\Roaming\Unity\Asset Store). You can also find the latest version here: https://www.tridify.com/developer-tools/unity/
