Circular pattern feature in assembly

[breinkemeyer]

trying to pattern a bolt hole feature in assembly.  It fails to create the pattern definition.

// and add the hole pattern
oICollecton = .oITransObj.CreateObjectCollection();
oICollecton.Add(oIExtrudedFeatures[oIExtrudedFeatures.Count]);
if (endData.FileType3D == ".ipt")
{
oICirclePatternDef = oICirclePatternFeatures.CreateDefinition(oICollecton, oISMCompDef.WorkAxes[1], false, 4, oDeg, true);
}
else
{
oICirclePatternDef = oICirclePatternFeatures.CreateDefinition(oICollecton, oIAssyCompDef.WorkAxes[1], false, 4, oDeg, true);
}
oICirclePatternFeature = oICirclePatternFeatures.AddByDefinition(oICirclePatternDef);
oICirclePatternFeature.Name = "Flange Brg Bolt Pattern";

It works fine for the sheet metal file but not the assembly.  Am I missing something?

Hi @breinkemeyer 

Assembly level patterns are similar but different than there part level counterparts. 

One major one is you need to tell the pattern about its participants. See help page here.

Syntax

CircularPatternFeature.AddParticipant( Occurrence As ComponentOccurrence )

So it turns out the easy fix is to replace the addbydefinition method with the add method...

oICirclePatternFeature = oICirclePatternFeatures.Add(oICollecton, oIWorkAxes[1], true, 4, "360 deg", true);
