Hi Lorena,
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 Extrude
{extrude-list} Using Wire {expression-list} ; command is available in addition
to the old set of Extrude commands for translations, rotation, etc.
Now, if you want to extrude a point along translate vector, you can simply use
the old command : out[] = Extrude {extr_vect_x, extr_vect_y , extr_vect_z } {
Point{point_id} ; } ;. That will return the extruded point id in out[0] and the
extrude line segment id in out[1].
The Extrude Using Wire 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.
Let me know if it helped,
Sincerely Yours,
Guillaume DILASSER

Objet : [Gmsh] Extrude function does not show the extruded point's id anymore
Hello!
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.
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.
In version 3.0.2 line[] has only one element, line[0], which is the id of the
line that connects the two points.
I really need the id of the extruded point.
Is there any other way I can find it?
Thank you!
