The detail below shows most of the basic elements of the portal frame that will be drawn by the plugin:

The PF King Stud and PF Trimmer Stud parameters will allow the user to increase the quantity of the king and trim studs accordingly.
The PF Bottom PLT parameter will allow PF Bottom Plates to vary from zero, one or two.
Optional head and jambs studs can be specified (shown in red).
The detail shows a double portal frame, a single portal frame is very similar with one side conventionally framed and one side portal framed as shown.
The light blue elements are the regular studs (or cripples) on their typical 16" o/c spacing.
PF C2 and PF C1B are probably optional elements but I like to include them, please let me know if there are any objections.
For now only strap holdowns will be available since this seems to be the prescriptive path most people employ. However in my professional opinion other holdown types (HDU) could be permitted provided that the proper engineering has been done.
Eventually I will include a PFH calculator in the plugins engineering module based on my own Excel based Portal Frame Calculator:
