Have a look at the attached pictures. In an assembly I used a hole wizard feature to cut a hole in the invisible face. I then used a linear pattern at the assembly level to pattern the hole at a spacing of three inches. Both features are propagated to the part. After the creation of the pattern the face appeared 'see through'.
Does anyone know what is happening here?
Strange but I flatten the part, did a Ctrl + q (force rebuild) and finally back to normal state. Result: Part is good as desired.
