TestFit 2.10: Structured Spaces

written by
Clifton Harness

In today’s update we release Structured Spaces or “spaces in the garage”. This feature has the distinction for being, one, almost universally requested, and two, requiring nearly a year of work (1/3 the lifetime of TestFit) to build. It will drastically change how almost all buildings are generated and interacted with. Check it out below.
