Ilogic Multivariable Parameter Creation Rule

[Anonymous]

Have this snippet of code where parameter "COLOR" is created as user parameter if it does not exist in a part.  How can I make multivariable parameter that would appear as drop down menu with multiple COLOR options:  RED, GREEN, BLUE, etc?

Easy to create multivariable parameter list in the part but this code will add them to old parts created before the COLOR parameter was important.

doc = ThisDoc.Document

Dim oPartCompDef As PartComponentDefinition = doc.ComponentDefinition
Dim oParams As Parameters = oPartCompDef.Parameters
Dim oUserParams As UserParameters = oParams.UserParameters
Dim ParameterChecker As Parameter
Try
ParameterChecker = oParams("COLOR")
Catch
ParameterChecker = oUserParams.AddByValue("COLOR","RED","text")  ' how to make drop down list:  RED, GREEN, BLUE, ....
End Try

Hi DavidBapst,

Here's a quick example rule to look for a paramater list for color, and create it if it is not found, and then set the part color.

I hope this helps.

iLogicVb.UpdateWhenDone = True

'check For Parameter and create If Not found
Try
	'get parameter value (just to see if it exists)
	oTest = Parameter("Color") 
Catch
	' Get the active document.  Assumes a part document is active.
    Dim partDoc As PartDocument
    partDoc = ThisApplication.ActiveDocument
    
    ' Get the UserParameters collection
    Dim userParams As UserParameters
    userParams = partDoc.ComponentDefinition.Parameters.UserParameters
	
	'create the parameter
	oParam = userParams.AddByValue("Color", "Red", UnitsTypeEnum.kTextUnits)
End Try

'Set the list
MultiValue.SetList("Color", "Red", "Default", "Gray")

'Get user input and set color
iProperties.PartColor = InputListBox("Choose a color.", _
MultiValue.List("Color"), MultiValue.List("Color").Item(0), "iLogic", "List of Colors:")

Multivariable parameter list creator works great thanks!  How can I make the variable "Key".  Also, the parameter gets added to end of parameter list - any way to auto sort the list by "KEY" parameters after creation?

Hi DavidBapst,

To set the parameter as a key you can add this line:

Parameter.Param("Color").IsKey​ = True

As for the other question, I assume you're talking about in the Form Editor? If so, I don't know of a way to sort or re-order, but you can filter for keys:

Or if you mean in the Parameters Editor you can click the header to sort, and use the filter button to filter for only Keys:

I hope this helps.
