@quentin2.chevrier — as @sovitek mentioned, it’s recommended to use adaptive components with two or three points.
I’d also like to reference this Autodesk University class, which is relevant for @ATTEL9DCS. It presents a TBM tunnel modeling workflow:
Parametric Modeling and Automating Placement of Universal TBM Rings (AU 2021)
Additionally, here is my class on how to model linear infrastructure in Revit:
Automated Linear Structural BIM (AU 2019)
Finally, this Dynamo package might be helpful:
