Hi, this is just a suggestion
after extracting the adaptive points from the excel just make them as a reference point in the adaptive family template.
select this reference point and create spline by clicking and create the axis spline of the tunnel.
select the spline and click divide path icon you can divide it as per your requirement
create a new adaptive family stating the profile make sure you draw your profile in top view and insert into it like the image below
select all the instance or up to a particular region create form and make the reference points adaptive
and again the place the family into project by using adaptive component by points node from the excel input point
have a nice day
