Dear list,<br>
<br>
just to answer my question myself by some private help of Herbert:<br>
<blockquote cite="mid:493E979A.7090200@acrotex.net" type="cite"><font
face="Myriad Pro"><br>
When using<br>
<br>
</font>
<pre wrap="">\pcline{|->}(O)(B)</pre>
<font face="Myriad Pro">the bar is as well scaled, which for sure
makes
sense. Is it nevertheless possible to suppress the scaling of the
bar(s) -- I would like to have ONLY the arrowhead definitions globally
for a large document. Your solution is fantastic for the given example
-- however i have a large amount of some other graphics with bars and
vectors and there it doesn't look too good with that thick bars.<br>
<br>
</font></blockquote>
<font face="Myriad Pro"></font>Here the perfect result to suppress the
thickness of the bar that was added; _pstricks-add_ offers a
WON-DER-FUL command named: \resetOptions, that sets all values to the
default values and that now allows to overwrite some globally set
pstricks settings easily locally within the \pspicture environment --
very cool!!!<br>
<br>
Herbert, keep as well on trucking on the experimental pstricks-add and
maybe you will move the \resetOptions to the basic pstricks package --
really useful for locally or globally resetting the values to the
default. Indeed this trick solved all my problems to setting values
globally vs. locally. <br>
<br>
Yoodle!!!!<br>

Thanks a lot for your steady work and maintainance of the powerful
PSTricks bundle.<br>
