<html>Thank you so much!!<br /><br />I am using a geo file with which I can create a png file using the display but I cannot create <br />it online, could you please comment on this?<br />I have taken the critical points from a post from Prof. Geuzaine's:<pre>Extract of the geo file:
.......
< deleted stuff for merging the step files >
Merge "Walls_Unit__0__Wall__6.step";
SetFactory("OpenCASCADE");
// display stl mesh of CAD surfaces
Geometry.Surfaces = 1;
Geometry.SurfaceType = 0;
// display curves as 3D cylinders
Geometry.LineType = 2;
// specify model rotation using Euler angles
General.Trackball = 0;
General.RotationX = 0;
General.RotationY = 0;
General.RotationZ = 0;
// print image
Print "test.png";

<i>
</i>Forever grateful for providing us with this fabulous tools and all your effort in support.
I am working with gmsh without user interface in an optimization process where everything is driven with command line gmsh options in shell scripts.
I just want to load the step files, export the resulting view, what I would have seen if I were working with gmsh with display, to png file, and that is it.
Can I do that?
Thank you very much for reading.
Best regards.
