Prototyping in Axure can be rewarding because it allows for mocking up complex systems. It's also an efficient tool to create smaller mockups to refine design ideas, to get buy in from stakeholders, and to run user tests. Below are examples of prototypes I created in Axure as well as other tools.
Shoppa is a prototype of an online auction platform, but with some additions and rethinks. With a sales site like eBay users can see previous sales, but have no way to compare them. Even someone who only sells 10-20 items per year could benefit from being able to see a better historical representation of where they have made their money. This could save time in the future on selling items that take too much effort vs potential reward.
Another detail is the idea of "continuing on" instead of manually having to go add another item for sale. The user could either list another of what they're currently looking at, or start typing into the fields below the currently viewed item.
Illustrated in the sketch below at left the user can see all of their items, both for sale and sold in the same location. Again, to compare with eBay, users often have to click back and forth between different sections to keep track of items that need shipping, re-listing, or are just waiting for a buyer.
In the 2nd image, I was thinking through how a continuously scrolling interface might work that also allowed the user to get details of the items scrolling by.
Another step was the creation of information architecture documents. I'll often start out in something like OmniGraffle, but in this one I finished it using Axure.
Last is a sketch for a social site. I was figuring out which elements would go or fit on each page.
I've created prototypes using many methods. Sketch, paper, objects/models, Axure, UXPin, Sketch, InVision, Proto.io, Marvel, Adobe XD, Keynote, CSS and more. I see many exciting possibilities for prototyping reality using VR and AR.
