Hi Corina,
Thank you for bringing this issue. We missed the support of AllAroundSymbol? Parameter in IvSurfaceTextureSymbol Design.
We are planning to fix it in future ETO version.
The workaround exists, based on Inventor API.
1. Create new Design IvSurfaceTextureSymbolEx and redefine the modelself Rule in it:
Design IvSurfaceTextureSymbolEx : IvSurfaceTextureSymbol
Rule modelSelf As List
Dim handle As String = %%updateSelf
iv_updateSurfaceTextureSymbol( self, SurfaceTextureType, ForceTail?, Majority?, AllAroundSymbol?, MaximumRoughness, MinimumRoughness, ProductionMethod, AdditionalProductionMethod, SamplingLength, AdditionalSamplingLength, LayDirection, MachiningAllowance, AdditionalRoughness, SurfaceWaviness, Style, Layer)
GetHostObject(Me).set_AllAroundSymbol( AllAroundSymbol?)
modelSelf = { handle }
End Rule
End Design
The line in blue makes the trick.
2. Change the Design Name of the child, from :IvSurfaceTextureSymbol to :IvSurfaceTextureSymbolEx
Child IvSurfaceTextureSymbol_2 As :IvSurfaceTextureSymbolEx
part1 = Root.AdoptTest_1
entity1 = "Edge3"
intent1 = :midPoint
closestPoint1 = Point(0,1.5,0)
placementPoint = Point(-5,4,0)
SamplingLength = "Ra 0.8"
ProductionMethod = "poliert"
ForceTail? = True
SurfaceTextureType = :MaterialRemovalRequired
AllAroundSymbol? = True
End Child
Below is how the Surface Texture Symbol may look with AllAroundSymbol on and off:


Thank you,
