Reply To: Logo mesh – disappearing edge loops

Hi Craig,

You have one big Face ‘hiding’ behind the small Faces, which you can easily see when enabling Face Normals (sorry, this is 4.4, where ‘good’ is no longer blue, but transparent, but in 4.3 or before, turning on Face Normals would also show you the issue):

Select it, Delete it and your Edge Loop will behave again.
