I would like to know, if there is any way to create a new 'FeatureBasedPattern' within an assembly document. I have 2 assembly occurences - parts. In the Part1 i created a RectangularPattern of workpoints. The Part2 is going to be used in the new pattern. I tried the following VBA code, but it doesn't work.



Dim oAssDoc As AssemblyDocument
Set oAssDoc = ThisApplication.ActiveDocument

Dim oAssDef As AssemblyComponentDefinition
Set oAssDef = oAssDoc.ComponentDefinition

Dim oPart1 As ComponentOccurrence

Set oPart1 = oAssDef.Occurences.Item(1)

Dim oPart2 As ComponentOccurrence

Set oPart2 = oAssDef.Occurences.Item(2)


Dim oTG As TransientObjects
Set oTG = ThisApplication.TransientObjects
Dim oObjCol As ObjectCollection
Set oObjCol = oTG.CreateObjectCollection()
oObjCol.Add oPart2
Dim oExistingPattern As PartFeature
Set oExistingPattern = oPart1.Features.RectangularPatternFeatures.Item("PatternForAssembly")

'Dim oAssemblyPattern As FeatureBasedOccurrencePattern
Call oAssDef.OccurrencePatterns.AddFeatureBasedPattern(oObjCol, oExistingPattern)



The Call function breaks with: "Invalide procedure call or argument". I also tried "Set oAssemblyPattern = oAssDef.OccurencePatterns.etc...." instead of Call function, but with the same result. Same error for declaration change of "oAssemblyPattern" to "FeatureBasedOccurrencePatternProxy".


What am I doing wrong?


I am using INV2014, win7/64bit

Thank you for any suggestions,

Ok, i don't need help anymore... The point was the proxy geometry wich had to be created from the part pattern.

'Hi, i won't write here the "SET" declarations of all objects. I'll write just "DIMs".

'I have a Rect. pattern named "POINTS" created in a part "Belt". The part is palced in an assembly. Then i have another part "holder" placed in the same assembly wich is fully constrained. I want to use the "holder" and the "POINTS"  as inputs into the feature based pattern.


Dim oBeltInAss As ComponentOccurrence

Dim oBeltDef As PartComponentDefinition

Dim oAssDef As AssemblyComponentDefinition

Dim oObjCol As ObjectCollection

Dim oHolderInAss As ComponentOccurrence


'First, you have to get a pattern feature from the part

DIm oPatt As PartFeature

Set oPatt = oBeltDef.Features.RectangularPatternFeatures.Item("POINTS")    'or you can choose by number - for ex. Item(1)

'Then u have to create the proxy bacause of working in assembly

Dim oPattProxy As RectangularPatternFeatureProxy
Call oBeltInAss.CreateGeometryProxy(oPatt, oPattProxy)


'Now you can create the FeatureBasedPattern
Dim oFeatBasedPatt As FeatureBasedOccurrencePattern
oObjCol.Add oHolderInAss
Call oAssDef.OccurrencePatterns.AddFeatureBasedPattern(oObjCol, oPattProxy)

Set oPoleDilku2 = oAssDef.OccurrencePatterns.Item(2)


'Now the pattern shoud be created.

'Hope this helps at least a bit.:-) And sorry for my english..:-)
