Hi Verhegghe,

Thank you for the response :) ! I made the change but I was not able to export anything as I keep getting the warning that there is nothing to select.

I believe that there is an issue with my environment/installation as my code outputs (prints etc) are not being printed to the message section of the GUI. The outputs are only visible in the editor (VIM in my case). I am going to make another request for that issue.

Hello Paul,

Indeed, the wire stent example dates from the very beginning of pyFormex when there were no export functionalities in the GUI. Everything was exported directly from the script depending on the target we were exporting to (like in the WireStent_calpy example). I should update the example some day.

For now, you can easily make the stent available in the GUI by adding a line in the example's source, near the end:

    if show=='Formex':
        F = H.getFormex()
        pf.PF['Stent'] = F     # Export the stent to the GUI

For export to one of the pyFormex formats (.pzf, .pgf) this would be fine. For other formats, you may have to convert the Formex object to a Mesh first. You can do that in the GUI, or you can add the conversion directly in the line above:

        pf.PF['Stent'] = F.toMesh()

The Mesh can then be exported in .obj or .off formats.

I ran the wire stent example successfully and now I would like to export the geometry. However, when I attempt to do this in the GUI I am given a warning that no geometrical objects are selected. What needs to be done to export the wires geometrically?

Thanks in advance,
