Hi Erdmut, Thanks for such a detailed reply.
> 5 setlinewidth I added this line in box.ps, and yes, the box lines are quite thick. However, after doing an epswrite, to my surprise the lines were thin again. I installed the non-free gs-aladdin, and now it works - so there must be a slight bug in the epswrite driver of gs-5.5. > So, if you write your (simple) documents from scratch, things are > basically quite easy and flexible.

Actually using qcad (which uses qt to draw postscript). I have done my drawings with a linewidth of 0 and so qcad calls qt with a linewidth of 2*0 (I might change this to something larger). Thanks, Mark.
