"1001bit Tools has been my go-to plugin for five years. The stair generator alone is worth the download—it handles complex winders that would take hours to model by hand. If you work in architecture, this plugin fills the gaps in native SketchUp functionality perfectly. Highly recommended for speeding up the 'boring' parts of modeling so you can focus on the design." sketchup plugin 1001bit
