Python code errors

Hussain Al-Rizzo

I am trying to run two codes, attached, and receiving the following error messages:

at line 11: if app.ProjectName != project_name:

The first code to generate the antenna:

if app.ProjectName != project_name:
    app.NewProject(project_name)


if app.ActiveDesignName != design_name:
    app.InsertDesign("HFSS", design_name)

app.SetActiveDesign(design_name)

design = app.GetActiveDesign()

Appreciate your help to resolve the errors. Thank you

@Hussain Al-Rizzo a couple of things that will help get your question looked at by someone who can answer:

1) I have formatted your code as code, although it is too long for a post, and I am not sure it is right. You should try and break it up into just the parts that are giving you issues and use more generic examples if possible so that it can be parsed and answered more quickly.
2) If you can you should go in and edit the post and tag it with the application(s) and tool(s) you are using as that will make sure that the right SME teams see it.

Once you have done that, we can point folks at your question and get it addressed! Thanks,
Chris
