Grasshopper contour problem

Hello,
I have a problem with grasshopper contour and nesting. I made a wavy solid and I want to slice it for CNC cutting. The surface/waves at the model are smooth, but after I bake the contours from OpenNest, they look jagged/notched, not smooth waves.
How can i fix that?
Thank you!

Use the OpenNest ā€˜Transformā€™ output with the Transform component to make a better copy of the original geometry.

Thank you for your fast respond!
Iā€™m absolute beginner, I will try it tomorrow.
