Hi,

I’d have a look at the output of your ‘get parameter node’…

I’m guessing the output will say “LL” but it’s worth checking.

My suspicion would be that the LL is actually a Family Type, whereas you are checking for a String with your Equality test.

There is an ‘Object Type’ node in Dynamo that lets you check what sort of data is coming out of a node… If you plug that in and it says “String” then you’ll know you can check for it, if it says “Type” then you can add a “String from Object” node to convert the data into a Type which will work with your Equality test.

Hope that helps,

Mark

so is there a way to filter by family type and not parameter? I just want to filter the list so it only displays bars of shape LL

Hello, put a watch at the output of your ElementgetValueByname node

Once you have the Family Type, you can get it’s Name value and test that? :slight_smile:

Put x[0]
we must know the type of parameter 59 (I would go for a number 1 2 3)

Look at the parameters available after pulling the shape parameter - those Element Types will expose the LL value if you ask them for the right info.

Almost there. The problem now is it is not selecting multiple rebars. It only selects one
