How to remove nearly duplicate curves/lines

Rhino Rhino for Windows

So I have a bunch of 3d lines. I have a bunch of duplicates, but SelDup isn’t picking them up. My guess is that they are ever so slightly off.

Is there a command that will let me select and remove them? I’ve also had similar issues in the past with curves… something that would help with that too would be very useful.

Hi Tom- there is nothing built in for a SelDup with tolerance… it is a not infrequent request though. SelDup is super strict, it is not looking at the shape of the things in space but at the definitions in the database.
