Issue: Surface becomes transparent after splitting

Hi Everyone,

I have a flat surface with an array of holes. When I try and split the surface along the tangent of the holes, one of the surfaces becomes transparent.
I used the rebuild surface feature with DeleteInput() to develop a new surface with the holes untrimmed. When I try to develop the holes again the surface will become transparent again.
Can anyone please help with this issue. I have attached the work files.

Hi -
The mesher fails to create a display mesh with those trim curves. For this to display correctly in anything but wireframe, you will have to either move the holes or the bottom edge of the surface so that these are no longer tangent.
