Creating TIN using cross sections?

Question

I need to create a TIN using available cross sections, which I already have. I can use Create TIN, but the issue is that it would interpolate across to a nearby cross section which could be from another stream instead of using the the next available cross section on the same stream.

Is there a way to interpolate TIN in sequence using cross section station value?

have you tried using shorelines as a border? If you have any, that is. — alecsx, May 22 '19 at 07:34
Yes, but it doesn't work all the time. For meandering areas, shoreline method doesn't work — penguin, May 23 '19 at 23:36

Sounds like you have cross sections for multiple streams in one dataset. Use ModelBuilder or Python to select all cross sections for a particular stream (you'll need an attribute with stream name or similar), then run the create TIN using the selection.
