Hi Will, yeah it's kind of like a "batch mode" for one-rail type sweeping.

It doesn't do any kind of new shaping, it's just more convenient for applying the same profile sweep along a whole bunch of paths without having to repeat the sweep command over and over again.

The connection to Pipe is that previously Pipe was the main thing available that would handle doing a batch process for making a lot of tubes.

Pipe still may be useful for some special things since it includes the option to make hollowed out tubes. But also Pipe only is set to make a circular cross-section and not just any cross-section curve like regular Sweep.

But unless you want to make a whole bunch of hollowed out tubes, you probably don't really need Pipe anymore.
