Set definition on rectangular pattern not implemented?

[casper.vorm]

Hi.

I have a part where a pattern determines the placement and type of an inlet. I am trying to change the solid that is getting patterned by updating the definition, like so:

Dim new_def As RectangularPatternFeatureDefinition = oPartComp.Features.RectangularPatternFeatures.CreateDefinition(oBjCol, plane, True, count, offset/10, PatternSpacingTypeEnum.kDefault)
Dim rec_pattern As RectangularPatternFeature = oPartComp.Features.RectangularPatternFeatures.Item(pattern_name)
rec_pattern.Definition = new_def

But then I get an not implemented (0x80004001 (E_NOTIMPL))) exception. Instead, I have tried to find the pattern by name, delete it and then create a new one with the new definition, but it does not work every time.

Is there another way to update the definition, besides creating a new pattern?

Thanks in advance!

As far as  I am aware you need to recreate the pattern from scratch as there is no ability to modify the object collection once pattern is created.

You are saying your getting some results can you explain more about what they are? Some images wouod help and or show more of the error message using more info.

Hi again.

@dgreatice Thank you, I will take a look at that video later.

@A.Acheson Yes I can try. 

I'm not sure how much of the model I'm allowed to share, but essentially, I have multiple rectangular patterns that determines the location and type of specific inlets:

As per the documentation, RegtangularPatternFeature.Definition Gets or Sets the definition of a pattern object, meaning I should be able to update an existing pattern right? I need this to update what solid is patterned at each inlet location.

However, when i try this i get:

As a workaround, I have tried to iterate through the patterns, delete them and create a new ones with the same name but a different definition, to update the inlet type. sometimes this works, but other times I get an null reference exception. I have attached the code.

So it seems I have solved one of the problems. When I deleted a pattern and later created a new one with the same name it sometimes gave an error. By accessing the definition object, i could update the solids that were getting patterned to different ones. 

However, when I try to set the spacing:

Dim rec_pattern As RectangularPatternFeature = oPartComp.Features.RectangularPatternFeatures.Item(pattern_name)
rec_pattern.Definition.XSpacing = offset

 I also get a "Not implemented (Exception from HRESULT: 0x80004001 (E_NOTIMPL))" exception.

Is there anywhere I can report this? I couldn't really find a specific forum for it.
