Good to know, thank you for your help @JParis

Changing the Background fixed the problem. Thank you all for the help!

I have the Quadro 2000 made by Nvidia

Desktop

Again, the file I am using as an example only has one active level. it is on.

Let me know if this works. Surface Finish Flowline.ZIP @crazy^millman

I created a single surface on one level in the image above. That is not the issue. @crazy^millman

I use surface finish flowline when programming often and I noticed the lines that appear under flowline data are missing. In the flowline data box I can see my surface that is selected and I can change my cut direction/step/start but I only see the arrow I do not see the "phantom" lines that used to appear, they would display which direction the toolpath would go. I am wondering if this is a graphics problem or if I accidently changed a color in my configurations. I am not sure what to call these "lines" so I am having a hard time trying to solve this problem. I am using 2022. When I was programming with 2021 I did not have this display problem. Any advice would help, thank you!
