I have a closed spline with 18k co-ordinates completing it. My machine shops have been complaining that when i send them a dxf , step or even the original solidowrks file & when they would import it into their CNC mills the smooth curves end up becoming flat lines as you can see in the picture.
This is even after trying to send it by setting the highest possible image quality settings.
I would like to know if there a setting i need to look for while converting OR instructions which i need to let my machine shop.
The smoothness of the profile is the most important thing for the part.
