Yes I know! It seems to be only accessible to download from Autodesk Desktop App. However what this looks like (executable to install, its name in Programs and Features, where it's tools are located in Revit) ALL seems to have changed from years past. For instance, the install exe for 2023 is named MEPFabricationPartCommands.exe. For 2020 it wasRevitFabricationExtension.msi. For 2021 it was RMFPC.msi.
Also the Add-In Ribbon does not seem to contain similar tools.
Can someone clear this up for me?
