Hi Rogurt, re: select loop - select loop works by selecting edges that are part of the trimming boundary of one surface. It works on some other areas of your model because you've got a big surface in the front here:


In the area that you are asking about there are a bunch of little surfaces and not one big one:




The select loop method only works by selecting a boundary that belongs to one face like the one on the big face, it does not know right now how to cross over edges that belong only to a bunch of little separate faces, that would be a different type of loop traversal method instead of the trimming boundary method that it currently uses.
