Hey there,

I try to export a radiation pattern (3D) in the .stl format. That's my code:

fc = 62e9;
pm = design(patchMicrostrip, fc);
pattern(pm, fc);

Now it would be great to export this pattern as .stl or something similar. I'll be greatful for every idea or hint.

Thanks in advance!

在 MATLAB Online 中打开

demoFile.mlx

I thought about (and tried them):

> stlwrite (part of the antenna package), which needs a triangulation object as input, but i couldn't find a way to convert the 3D-pattern to a triangulation object

> surf2stl (https://uk.mathworks.com/matlabcentral/fileexchange/4512-surf2stl), which needs a Surface as input.

h = gcf;
get(h)
children = h.Children
axChild = children(6).Children

This shows me that "Axes" has a Child of type Surface. I can export this to an stl without problems, but it's just a sphere. So there has to be some information missing.

Thanks in advance for any helpfull idea!
