Creating User Parameters with iLogic

[jprochaskaYBH3W]

I am trying to create multi-value user parameters with iLogic, my rule works but when ran it sets the initial value to an arbitrary (or it seems so to me) value that is not in my list.  In this instance it sets the value to 4.03543307.  Once I manually go in and change it to a value that is in my set list the 4.03543307 goes away but I'm wondering why it sets the value to something I haven't assigned.  

Any help is greatly appreciated! Thanks!

Imports  Inventor.UnitsTypeEnum


Dim oPartDoc As Document
oPartDoc = ThisDoc.Document

If oPartDoc.DocumentType = kPartDocumentObject Then

	Dim oPartCompDef As PartComponentDefinition
		oPartCompDef = oPartDoc.ComponentDefinition
		
Dim oParams As Parameters
		oParams=oPartCompDef.Parameters
				
		Dim oUserParams As UserParameters
		oUserParams=oParams.UserParameters       
		
		Dim Width As Parameter                     
				
		Try
			otester = oUserParams.Item("Width")
			Catch
oInsulationType=oUserParams.AddByValue("Width", 10.25, kInchLengthUnits) 
MultiValue.SetList("Width", 12.25, 14.25, 16.25, 18.25)
			End Try
            End If

Parameter.Param("Width").ExposedAsProperty = False
Parameter.Param("Width").IsKey = True

I'll give you a hint... 😉

convert 10.25 cm to inches = ??

[jprochaskaYBH3W]

Ahh yes, but why if I tell it inch units would it default to centimeters? 

I thought I remember reading that iLogic does all its calculations in the background in metric, but I thought it would automatically convert it back to the units specified.

Is there an easy way to convert it without manually putting in the conversion?

You can use AddByExpressions instead and put your number in quotations

oUserParams.AddByExpression("Width", "10.25", kInchLengthUnits)

[mcgyvr]

oInsulationType=oUserParams.AddByValue("Width", 10.25*2.54, UnitsTypeEnum.kInchLengthUnits)
