Hello Michael,

I hope you are doing well.

I've got a question for you. I noticed in the "commands folder" most of the add-ons require or let's say required "_" before their respective file names. However, I noticed it seems for the Reconstruct Curve Script "_" is not needed to be added, am I right?

and may I know the reason?
