Force to Change a Parameter

[Anonymous]

Hello,

I have some iLogic Code that checks the clearance between two of the features.  I have set up the code in this manner:

If Parameter1 - Parameter 2 <= 0.300 Then

Message Box (Error Message)

ILogicForm.Show(Form)

End If

I can force the Form to open, BUT I can just hit the cancel button and while Parameter1-Parameter2 is in an error condition it will just generate the part as if nothing is wrong.

I want to force the user to edit either Parameter1 or Parameter2 so the clearance check will run again.  Please advise.

Thanks!!

I would try something like this:

SOURCE: https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/statements/do-loop-statement

Do While (Parameter1 - Parameter2) <= 0.300
    ILogicForm.Show(Form)
    RuleParametersOutput()
    InventorVb.DocumentUpdate()
Loop

What does the last two lines in that code do?

RuleParametersOutput ()

InventorVb.DocumentUpdate()

I am fairly new to using iLogic so some of the syntax is over my head at the moment.

Thanks!

So when I put the code you mentioned in my Rule it creates a never ending loop.  The Form will open, but I do not get a cursor to change any of the values.  It is always the loading circle.  Please advise.

Thanks!

Hmm. might have to use the Parameter("Parameter1") calls to fix it to force them to update. Could also be an issue with code running in the background during the forums.

Something to try and investigate.

The inventor Parameter functions page, linked through LMGTFY, should provide some more documentation on the Parameter calls.
