<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Hi Lorena,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Are you sure you are not mixing up two different Extrusion commands ? Since Gmsh 3.x and the inclusion of the OpenCascade
factory, the new <i>Extrude {extrude-list} Using Wire {expression-list} ;</i> command is available in addition to the old set of Extrude commands for translations, rotation, etc.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Now, if you want to extrude a point along translate vector, you can simply use the old command :
<i>out[] = Extrude {extr_vect_x, extr_vect_y , extr_vect_z } { Point{point_id} ; } ;</i>. That will return the extruded point id in out[0] and the extrude line segment id in out[1].<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">The
<i>Extrude Using Wire</i> command is a new addition that allows to extrude a geometrical entity (most often a line or surface) along a spline (defined as a Wire). This command is also exclusive to the OpenCascade Kernel, it is useful if you want to build models
of pipes, cables and such. Anyway, I do not think that you need it for what you are trying to achieve.<o:p></o:p></span></p>

<p class="MsoNormal">I have been working on gmsh version 2.8.3, but now I've turned to version 3.0.2 where I found some problems with the Extrude function.<o:p></o:p></p>

<div>
<p class="MsoNormal">When pressing the command: line[] = Extrude {1, 0, 0} Using Wire {Point{50};}; in version 2.8.3 line[0] was the id of the extruded point and line[1] was the id of the line that connects the two points.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">In version 3.0.2 line[] has only one element, line[0], which is the id of the line that connects the two points.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">I really need the id of the extruded point.<o:p></o:p></p>
