I can not fully understand your question.
Are you referring to create a form in PDF and then import it?
I do not think that this could be possible, even though there is a guide to import PDF forms, it only works with Adobe FormsCentral PDF forms.
You will need to make the form in our Form Builder.
If your question is related to PDF fillable forms, then take a look on this guide for further details about it: http://www.jotform.com/help/312-Fillable-PDF-Everything-you-need-to-know-about-JotForm-Fillable-PDF-Creator.
Hope this helps.
