Split closed curve into two equal segments

Hi everyone, I’m looking for help with splitting a closed curve. I’ve already tried rebuilding the curve, setting the degree to 1, splitting it at the midpoint, and then changing the degree back to 3. However, I wasn’t satisfied with the result. The reason I want to split the curve is to create a surface using the Sweep 2 Rail command. I’ve attached the image/file of the curve I’m trying to split. Any suggestions would be greatly appreciated!

Assuming you want to split into equal length segments: Command “Divide”, nr. of segments 2.

For non-equal segments, draw one or more splitter curves across your closed curve and use “Split”

Or, run Split, choose the Point option and pick at least two points on the curve - you can’t split closed curves with only one point.
