    • With the v3.11 .msi installer, there is a new feature “Naviate AI” listed in the Custom Setup step of installation. See above. Note: v3.11.2 installer will now default “Naviate AI” set to OFF. This is a new option to enable or disable all AI features in Naviate:

    • After initial installation of a v3.11 Naviate Core.MEP.Fabrication, there are three (3) ways to modify Naviate to enable “Naviate AI” from OFF to ON:
