<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">as far as I see, your point coordinates are wrong, i.e. if point 2 is your center point, points 1 and 3 do not lie on the same circle. So it is no bug.<o:p></o:p></span></p>

<p class="MsoNormal">Dear,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">I’m not entirely sure if I’m going mental now (:-s), but I’m trying to create a very simple circle :
<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">lc = 1;<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Point(1) = {0, 50, 0, lc};<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Point(2) = {90.0,-42.0,0,lc };<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Point(3) = {154.0,93.0,0,lc};<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Circle(10) = {1, 2, 3};<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">However, for some bizarre reason, the circle doesn’t go through my 3th point. See screenshot below… I have absolutely no idea what goes wrong here. Maybe I’m missing something ??? I don’t really get any errors as well.
I’m using gmsh 2.8.5 on windows 64 bit. But I’ve tried with the linux version as well, same problem. At first I though I had made some mistakes in some calculation I was doing before, but when I stripped everything down to the bare coorinates (see .geo above),
I get the same error…<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">Many thanks for any light you can shine on this.<o:p></o:p></span></p>
