Context
As a Roblox developer, it is currently too time-consuming to iteratively build a symmetrical object.
The more complex the structure, the greater the benefit.
The Ask
If I had the ability to define an axis, whether ephemerally (i.e. baked-in, meant for quick one-shots) or permanently (i.e. always there, fast iteration, multiple sessions), and have structures mirror across/along it - it would improve my development experience because I could more efficiently create and iterate upon complex symmetrical structures.
Misc
Procedural models exist (and could potentially even be leveraged for this), but this feels like a core base functionality that should just exist in the default Studio toolset.
