<p class="MsoNormal"><span lang="EN-US">first I would like to thank you for your great work. I really like to use your software and enjoy the very good mesh quality. Nevertheless, I have a problem with 2D meshing of compound surfaces/curves.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">As far as I understood, compound curves are handled like one line in the meshing process. But in the attached example, compound curves are meshed differently from line elements.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">It seems to be, that all compound curves are meshed by at least four nodes. This happens even if a very coarse density is choosen. If you please have a look at the attached example:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Compound Curve 141 {11 33} is meshed by three lines (four nodes) but Line 2{0 18} by one line (two nodes) only. For all points, the same density has been choosen (lc=100), which should lead to a very coarse mesh.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">How could this behaviour be avoided?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">I would appreciate very much to receive your answer to this problem.<o:p></o:p></span></p>
