Hi jeff and Jeff,


Thanks both for replying.



To limit the number of mails, I'll reply to both of you in one mail.


Jeff,

Thanks. I am aware of that. As this is only for visualitation, I'm just
looking at the different options out there.
The people giving ham-radio classes are not necessairy people who have a
very solid background in computers, so that is why as I was looking for
an option that is as simple as possible to use.

I know there is the possible to export radio-patterns into a format that
can easily to viewed in 3D?

Some antennas (not all are my designs) in 4NEC2:

I asked Arie Voors (author of 4NEC2) if he could provide such a
feature. I'll spare you the details, but basically the answer was no.

To bad 4nec2 isn't open source.



I'll concidering writing something myself to do this as there are python
libraries that interact with nec directly.
Perhaps it would be a good exercise to learn more about the 3D plotting
libraries in python.

You methode looks interessing but seams to require a lot of manual work.

I'm a bit surprised there are no standard way to visualise 3D wireframes
objects.
