For something like 'path' shelf setup, I think the best place to ask is Houdini
forum, maybe there is someone from SideFX team able to say about reasons for
such setup. Don't believe a lot of Houdini users use this thing.It is setup, by
structure (not by functionality) similar to Maya shelf setups like Flow Path.
It creates a bunch of SOP nodes and CHOPs, in order to get 'oriented' curve,
suitable for calculating the orientation of objects constrained to path. By
using MMB over 'ordinary' curve created by Line or Curve SOP, you'll see only
the P (position) attribute, while last SOP in 'path object' displays calculated
normal and few more. By the way, some created SOPs are old, deprecated versions.

the question I should be asking is, is there a Houdini mailing list? But
putting that aside, the thing I really wanted to know is, what’s the practical
difference between a path and curve in Houdini? I’ve learned I can path
animate on both, but each creates a “curve” in different ways and I’ve been
unable to determine what might be common or similar between them. I’m finding
paths to be very cumbersome because they create so many cv objects that are not
part of a unified path object. I can see advantages to that but the
disadvantage is that large paths are difficult to manage. And curves seem
significantly difficult to edit with precision, at least easily compared to
paths. So whats the difference? Why one vs the other and what uses are they
best for. Joey ------
