Reversing the even rows of uv points from a trimmed surface

I have generated some uv points obtained from a trimmed surface. The number of uv points vary depending on the way that the surface has been trimmed.

I need to reverse the order of the even rows because I am using these UV points to drive a ball-nosed cutter so would need to have it going in a zig-zag pattern.

Many thanks

William

You can use [Split Tree] to separate out the even and odd rows, then [Reverse List] on the even ones and merge the two trees back together.

Unfortunately, it does not work for trimmed surfaces. Many thanks. William

The example above is a trimmed surface.

The curve has been converted to a planar trimmed surface.

Can you post your example?

Just found where the error was. Basically I had selected one of the trimmed surface using the list item. I then activated the flatten on the Sdivide. It now works. Regards William
