Hi Sönmez,
There is a German language ArchiCAD forum here:

To control the thickness of your lines when you print, you will want a different pen set. Each placed drawing can refer to a pen set. So, for small scale drawings, you will want a pen set with thin pens, and for a large scale detail, you'll want fatter pens.
I cannot quite understand the first question about insulation - are you asking if you can have an insulation symbol appear automatically inside your wall in section? If so, the answer is 'not really'. You can choose any fill for the wall or slab cavity - so if you want a pattern for rigid insulation, that is easy. But a wavy line for batt insulation is not easily possible - it has to be added as a 2D overlay, for example with the insulation library part.
Cheers,
Karl
