Your .3dm file is R7 so can’t be opened in R6. Internalized geometry is best, or save an R6 version of the .3dm file. But it apparently is not needed?
You can get your eight intersection points by grafting the ‘A’ input and flattening the ‘B’ input to CCX.
Or you could adapt yesterday’s code like this - see cyan group:

The reddish ‘Dimensioning’ group can be discarded.
Oh wait, besides the vertical lines from the cyan group, you probably want to shatter the horizontal lines and ignore selected segments? Back to the tabbing thread! Correction:
OK, look, I think this is where you’re going with this? You don’t need CCX to get there because you already have the ‘t’ values from the Evaluate Length points. (orange group)
