Trim Solid - not working for some strange reason


I have got a question about the Trim Solid (trim command). I would like to trim (making holes) in a surface.
Trim surface (249.7 KB)
I Have done this in 2 manner. In both manner I start maken a surface --> extruding this surface, after which I would like to trim this volume from a predefined (larger surface). However, the strange thing is;

  1. Does work
  2. Does not work

I cant figure out why the second is not working. If you have any suggestions, you are welkom :). See GH file attached.



thank you in advance
