Line Thickness in UML Diagrams

[Barthelemy Longueville lgi ecp fr]

Hello everybody,
 
I'm re-posting a question from Alexander Schmid (Mon, 27 Jan 2003) about line 
thickness in UML diagrams.

I use dia 0.91 (from sources on a mandrake 9.1 box) to draw UML class diagram.
The diagrams are exported as eps files and included in a postscript of pdf 
document (LaTeX).

I would like to reduce the thickness of the lines of the UML diagram. The 
current thickness is too high and my diagrams don't look as nice as they 
should !

Lars Clausen said that :

I would like to know how to modify the global des of their linewitdh. I'm not a 
hacker but i'm able to modify the source code if necessary and to compile dia 
again if I know what do to.

I have to solve this problem quite urgently and dia is definitly the best 
solution i found to create easilly nice uml class diagrams that can be exported 
in *.eps format.

Thans for your help !
