The option of "draw helix" in my toolbar in HFSS is deactivated. does anybody know how can I activate it? I simply wanna draw a helix and I can't as it is disable in the setting of my HFSS.
I think in the new versions of HFSS if Antenna Toolkit is available Draw/Helix is deactivated because helix design is available through: Draw/User Defined Primitive/SegmentedHelix
From there you can build a PolygonHelix or RectHelix.
The cross-section of the wire can be changed from "User Defined Primitive Operation". For example PolygonSegments = 0, means the wire cross-section is round. The default value is 4, which is a square cross-section.
