Asymmetrical results when rebuilding a curve

Hi I’m having an issue with the rebuild tool recently, I’ll usually join several curves, then use the rebuild command to tidy up the pivot points. But often times, the results aren’t symmetrical, even though the original curve is symmetrical.

How would I fix asymmetrical rebuild results?

Thanks in advance.

please share the file with the curve before rebuilding, also which rebuild did you use? Rhino has several options to rebuild here

Hi Encephalon, thanks for replying. I used the Rebuild command, the one which you simply type “rebuild”.

FYI, I chose to rebuild with the point count to be 14, and with degree set at 2.

The file below is the curve I’m trying to rebuild, it would be great if you could provide some insight, thanks in advance!
