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 ‘_Transform_’ output with the Transform component to make a better copy of the original geometry.
