An idea inspired by the game Empyrion - Galactic Survival.
In this game there is a dedicated mode where you can build freely without constraints related to the environment, resources or survival. You can take your time to finalize your project, save it, leave, come back... When everything is ready you can make a blueprint usable in a playable world. We open the blueprint. A virtual structure appears that we can place as we wish by adjusting the position, height, rotation. You validate and that's it. All that remains is to add the resources.
It's very practical and it allows you to concentrate and enjoy the architecture part without being bothered by the day/night cycle, hunger, enemies etc...
