changing from one multi list to another in ilogic inventor Pro 2019

[Anonymous]

I'm trying get a sheet metal template to work for bending round bar.
I'm looking for a rule and form that changes when you pick the material and then the thickness.
unfortunately the material diameter is different for round bar as it is for bright bar and Stainless Steel
my form needs to pick a material and then changes between the diameter list based on the material selection.

Hi Peter,

I don't think this is a good practice. Sheet Metal Materials and Thickness should be managed by Sheet Metal Rules. Changing Thickness parameter or Material style outside of Sheet Metal Rules will only add confusion. It is a shortcut. But, it is not the right way to do it. You should create Sheet Metal Rules for all permutation of material style and thickness. Then you can use iLogic rule to activate one of them.

Many thanks!

Thanks that's great I may have inherited a bit of a mess, but i'm on a better path now.

Also, whenever you want a later list of options to change based on what you choose in another earlier option on a form, usually the best thing to do is have a rule that is triggered by that earlier parameter change, that uses the MultiValue.List or MultiValue.SetList to redefine the ExpressionList of the later Parameter.
