set thickness of only one part of line

[Stefano150687]

Hello everyone!!!:smile::smile:

I have a little problem... .

I have autocad version 2009 and I happen to make drawings with sections. at school they taught me that the line part with arrow and letter goes bigger. how do I autocad change the thickness of only part of a dotted line? ? ?

:confused
