How to access part parameter in an assembly using VB.net

[bwang-tecoustics]

iLogic use:

Parameter("Part1:1", "d0")

But how to do this in VB.net? The part1 is in a assembly and I want to change a parameter in the part.

here's the help document you need. This is also located in your Inventor aswell.

Thx. I was able to use the code below to access the UserParameter in the assembly. As the oOcc is the ComponentOccurence of the part, and its Parent is the assembly file. But what I'm trying to do is to change the value of the UserParameter in the part file, which is the oOcc itself.

oParas = oOcc.Parent.Parameters.UserParameters

The other question is the UserParameter.Value is an object per the help file. what should I do to change it's really value? Does Inventor treat the dimensions like "2 in" or "30 mm" as object?

Finally, I could use the following code to modify the UserParameters in the part file.

oOcc.Edit() 'Edit the part file in the assembly
                        Dim oPDoc As Inventor.Document
                        oPDoc = _invApp.ActiveEditDocument

                        Dim allParams As Parameters = oPDoc.ComponentDefinition.Parameters
                        oParas = allParams.UserParameters

oOcc.ExitEdit(ExitTypeEnum.kExitToParent) 'Exist editing after finish

If you already have the occurrence, the better method is this:

oUserParams = oOcc.Definition.Parameters.UserParameters

Editting the document first is cumbersome and much more resource intensive.

You can find this all in the API help....
