Hi niko - one thing that may be causing you some additional problems with network is that it seems that you're frequently trying to make a network that tries to conform to some non-rectangular outline.

I'm referring to this area of your network here:



Usually it is better for rounded corners like that to be formed by trimming a larger continuous sheet, rather than trying to directly surface a non-distinct 4 sided boundary like that.

Anyway, that's just one tip that could help you out in general - it just seems that you're frequently trying to force surfaces to directly follow some kinds of shapes rather than using broader simple surfaces and then trimming those to produce the final cut out edges.
