Tt Library Sketchup Plugin |work| Jun 2026

Developed by the legendary SketchUp scripter , the TT Library (LibFredo6) was originally a set of common routines to avoid repeating code across different plugins. Over time, it evolved into TT_Lib² . It acts as the engine management system for a car; you don't see it, but without it, the car (the plugin) won't start.
