Not able to create xs from the model using civil tools "create xs"

I am trying to create XS from the model and I am using the create XS tools in the Civil Cell Tool bar. I chose 1:20 scale gave the model a unique name, went into custom tab and selected all my pattern lines and chose line string and hit graphics which loaded all my pattern lines. Then when I click apply it just loads super fast but do not create a model or XSs. Can you please tell me what might be the problem here?

Thank You.
