Importing 3rd party models into LTSpice

Trying to import the THS3491 model for an ADI signal chain with the AD8065 coming before that, 

I get the .lib file in correctly, then I try to auto-generate the symbol using what is in this presentation - highlight the .subckt line, right click, select create symbol =- and it does 

https://www.ieee.li/pdf/viewgraphs/ltspice_creating_a_schematic_symbol.pdf

However I would next like to start connecting things to that symbol and verify in the attributes it is linked to the right .lib path name, but all those keys are disabled up in the ribbon - how can I get past this ?

    Thanks for sharing the reference you used. I could help a lot more LTspice users here.

    I think you did well in generating the model symbol.

    I think you did well in generating the model symbol.
    When you need to start building the circuit with it, you need to open a blank New Schematic window or open one working schematic file. Then place the component by finding it from the [AutoGenerated] folder.

    Please see slide 6.


    I hope I am able to understand you and my answer helps.
