App Advice

Hello All,

I am trying to build an IOS app that will allow me to view houses from Revit in AR. I want to use an on-site image target to align the virtual world with the real world. Can someone give be some basic instructions/roadmap on how to go about this? My basic idea is as follows:

Create new 3D Unity project
Import Revit project using unity reflect
Add plants
Add qr code to correct location in unity and somehow use that as an image tracker
Move AR session origin to 4' above qr code
Export project and open project on mac and deploy app
Go place qr code in real world and see if it works

As you can probably tell I am new to Unity. Please let me know if this plan of attack sounds reasonable or if there are modifications I need to make to my game plan. Thanks.
