Hi @kamran.cad06. Solve that, create a new variable for superelevation that will look like this:

In input parameters, create the following:

Then apply the variable in the cross-slope field of your subassembly.

When you want to attach a PKT here, just change the extension to *.ZIP.
I hope this helps. Best regards!
