<pre wrap="">from what I see in the following example, the radius of a circle
created with pscircle
is an inner radius:</pre>

<font face="Myriad Pro">try and check the option: <br>
<br>
dimen=inner/outer (for the \pscircle)<br>
<br>
like in the following modified example from you:<br>
<br>
\begin{pspicture}(-4,-4)(4,4)<br>
\multido{\iA=0+1}{8}{%<br>
\cnode*(!2 dup 360 8 div \iA\space mul cos mul exch 360 8 div<br>
\iA\space mul sin mul){0pt}{A}%<br>
\cnode*(!4 dup 360 8 div \iA\space mul cos mul exch 360 8 div<br>
\iA\space mul sin mul){0pt}{B}%<br>
\psline{<->}(A)(B)%<br>
}%<br>
\pscircle[dimen=inner,linewidth=4pt](0,0){4}%<br>
\pscircle[dimen=outer,linewidth=8pt](0,0){2}%<br>
\psline[linecolor=red]{<->}(2,-0.1)(3.96472222,-0.1)<br>
%1pt=0.035277778cm<br>
\end{pspicture}<br>
<br>
Hope this helps.<br>
