As far as Occurrences in an assembly definition are concerned...

[oransen]

Is it true that as far as Occurrences in an assembly definition are concerned the top row of objects in the image below is the same as the bottom row of objects?

I.e. get_Occurrences (also) gets hold of the occurrences inside patterns? My experiments say it is true but I'd like some official confirmation...!

You can run this code to find out:

SyntaxEditor Code Snippet

i = 0
For Each oOcc As ComponentOccurrence In ThisDoc.Document.ComponentDefinition.Occurrences
	i += 1
Next
MessageBox.Show(CStr(i), "Title")

Hi @philip1009 , thanks for the code, but I've already done that test in C++. I was wondering though if there was somewhere where this is documented or defined.

[philip1009]

If you mean documenation as in a general API guide for Inventor, you can find that here when you have Inventor open:

Other than that, I do know that Patterns are another collection under ComponentDefinition alongside Occurrences, so it may be necessary to peruse both collections in your code.

The API documentation is pretty bad to be honest, apart from the examples. Full of thinks like:

IsBanana() a function which says is this is a banana or not

Looks a bit as if it was written automatically, thank God for examples!

I mainly use it to find the trails down to the code I want, then again I haven't developed code for any other software so I've no idea how API documentation is supposed to look.  However I find the examples annoying as they use older VB syntax that is no longer supported such as Let and Set statements, using Err to catch errors is no longer supported, so it's annoying to have to filter almost every example, and not to mention there are lots of examples missing parentheses at critical points that you have to find and correct as well.  Thankfully I've advanced enough to not have to refer to the examples anymore.

@oransen,

On creating patterns in assembly, pattern elements also acts as occurrences. So, it includes get_Occurrences()

Thanks and regards,

@chandra.shekar.gthanks fpor the confirmation.  🙂
