Hi! This should not be too hard. Here is a simple rule you can use. BTW, Length, Width, and Height are user parameters in a part.

Length=Measure.ExtentsLength
Width=Measure.ExtentsWidth
Height=Measure.ExtentsHeight

Many thanks!

Just to elaborate on Johnson Shiue comment. Here is an extract from my rule.

Play with it and adjust it to suit your needs. Also, as mentioned, you need to create the corresponding user parameters.

In my case, "HEIGHT,WIDTH,and THICK"

Dim oPart As PartDocument
oPart = ThisApplication.ActiveDocument
oDoc = ThisApplication.ActiveDocument

		'Turn off work features so they don't calculate
		oPart.ObjectVisibility.AllWorkFeatures = False
		InventorVb.DocumentUpdate()
Dim sizes As New List(Of Double)
sizes.Add(Measure.ExtentsLength)
sizes.Add(Measure.ExtentsWidth)
sizes.Add(Measure.ExtentsHeight)

sizes.Sort()
	Parameter("HEIGHT") = sizes(2)
	Parameter("WIDTH") = sizes(1)
	'Parameter("THICK") = sizes(0)
oPart.ObjectVisibility.AllWorkFeatures = True
iLogicVb.UpdateWhenDone = True
