Srf not displaying

srf not showing in display.3dm (129.6 KB)
Just ran across this. Can’t get it to display. What Ihave I done? — Mark I forgot to add that I am using SR25

you gotta clean those curves up. best you rebuild it at least the inner curve, since its really a mess. a trick would be to make a boundary box set to curves then fillet the curves with ≈ 0.22
