is it possible to cause the sweep sop
reference point input to use the point index?
currently using_aim_at_reference_points in
sweep does not register a change when:
one uses a transformed copy of the backbone
as the reference point input and then
re-sorts its point index with a sort sop.

Yea, the sweap sop must do a sort by vertex order on the fly which is blowing away your sort (just a guess). You can try a couple of things:

1) use a primitive sop and under the “Face/Hull” tab set “vertex” to “shift”.. then start shifting the U param.. this actually rebuilds the line and the sweap should like this

2) use an add sop and add the points in any order you wish.. so if you have 10 points in your line you can add a sort random, then an add sop making a new line from 0-9 and deleting the input geometry.. this rebuilds the vertex order in the order of the sort sop and it should work for you

beautiful. thanks Dank.
