Segmented Helix

[C-Ehmke]

Hello everyone,

I was looking through the documentation for a function that creates a 3D segmented helix, similar to what we have in Draw > User Defined Primitive > SegmentedHelix > RectHelix.

Is there already a function in PyAEDT that supports this?

From what I’ve seen, there’s only the create_helix function, but it doesn’t include all the parameters needed to generate the segmented helix geometry.

Thanks in advance for your help!

Best regards,

Hi @C-Ehmke ,

To create a segmented helix you need to use the create_udp method. As you can see this option is available in User Defined Primitive.
You can pass parameters as a list of list and then call the create_udp method:

udp_params = [
    ["RectHeight", "1mm"],
    ["RectWidth", "2mm"],
    ["StartHelixRadius", "10mm"],
    ["RadiusChange", "0mm"],
    ["Pitch", "3mm"],
    ["Turns", "2"],
    ["SegmentsPerTurn", "20"],
    ["RightHanded", "1"]
]

udp = m3d.modeler.create_udp(
            dll="SegmentedHelix/RectHelix", parameters=udp_params, library="syslib", name="my_helix"
        )

Hope this helps,

Kind regards,

Giulia

Hi Giulia,

Thank you for your reply! That’s exactly what I needed.

Have a great weekend!
