Sketchup Plugin — Tt_lib2

TT_Lib² installs a version checker that prevents loading two different copies simultaneously. If an older plugin tries to load an ancient TT_Lib (v1), TT_Lib² will override it or warn the user.

Before libraries like TT_Lib2 became standard, many plugin developers had to "reinvent the wheel" for every script they wrote. If a developer wanted to create a tool that manipulated geometry in a specific way, they often had to write the foundational math and geometry functions from scratch. This led to bloated code, compatibility issues, and instability. TT_Lib2 solved this by providing a standardized set of tools that developers could rely upon. By installing TT_Lib2, a user effectively installs a "standard library" that makes dozens of other powerful plugins lighter, faster, and more stable.

It provides a centralized set of core functions—mathematics, geometry processing, UI extensions, debugging tools, and memory management—so individual plugins do not need to reinvent common systems. This reduces code duplication, improves stability, and ensures consistent behavior across extensions. If a developer wanted to create a tool
