Fusion Appears to give striated model to slicing software

[controll21]

So I made this model and then saved it as a mesh and when I entered it into Simplify3D or Bambu Studio Slicer...they both turned out ready to print gcode with the gaps that you see.  This only recently started and it does not happen with every model....I am wondering if Fusion 360 could have something to do with it since both slicing software programs have the same issue....not from the same company.  Thanks

I do not see Fusion 360 native geometry in the file that you attached - only imported stl mesh rubbish?

OK Thanks for looking at it ....
