I created the curve on the right, but when I look at the top, they don’t align. Thank you for reading and helping.

It would be better if you can you upload your file? I can’t tell what’s wrong from the video alone.

I also think the problem is with the Cplane, but I don’t know how to fix it. Thank you for your help.

Try these commands:

Grid

(choose…)
– Show Grid = Yes
– Show Grid Axes = Yes
– ApplyTo = All Viewports

ZEA
(Zoom Extent All)… this should cause Rhino to redraw all of the viewports in one go.

These two alone should get all of the viewports back into alignment with a bit of agreement between them.

I’m sort of wondering if maybe this file got saved into Rhino’s templates Collection–it’s easy to accidentally overwrite them–but if it did you’re going to want to sort that out so this doesn’t show up the next time you start from that same point.

In any event this may not be a full fix… you mention snap not working for one thing, and maybe there are other issues too…
