How to allow the player to build adjustable curved walls in game?

I’m hoping to create a house building system similar to what is in the Sims 4 for example. I would like to include the ability to build and adjust curved walls in-game but don’t know how to go about it. Here’s an example of what I would like to accomplish. Is it even possible with blueprints?
