Closed curves don't stick to surface

because you have to pick the direction of the arraylinear on the surface rather than the cplane
choose one of the edges

Hi @japel22870
In the video, you turn on Project when drawing the circle and that forces your reference points to be on the Cplane. Turn it back off before setting the reference points or set the reference points in the Perspective or Top viewpoirt instead.

I guess that now the issue is how the circle is being created, if I do the linear array, the generated circles don’t stick to the surface, nor does the first circle

then, how can I make the first circle stick alligned to the rotated plane?

make a custom cplane to the surface object then make your array based on the new cplane-
