Rbz: Curviloft

Got a messy surface with holes or weird gaps? This mode brute-forces a triangulated mesh over the geometry. It’s ugly but functional—great for exporting to 3D printers or game engines. The "RBZ" Quirk (And Why You Care) You’ll often see it listed as Curviloft (RBZ) . That’s because RBZ is the developer's handle. Unlike modern "Extension Warehouse" click-to-install plugins, Curviloft originally came as a .rbz file (SketchUp's Ruby zip archive). You have to manually install it via Window > Extension Manager > Install Extension .

If you want to stop making boxes and start making bubbles, get Curviloft. It turns SketchUp into a proper surface modeler. Have you used Curviloft for a tricky project? The weirdest use case I've seen is someone lofting a snail shell using 300 rotated cross-sections. It took 10 minutes to process... but it worked. curviloft rbz

If you’ve ever tried to make a ship hull, a car fender, or a curved fabric canopy in native SketchUp, you’ve hit the same wall: The Sandbox Tools are clunky, and Follow Me is too rigid. Got a messy surface with holes or weird gaps

Enter by French developer Christophe (a.k.a. RBZ ). Released over a decade ago, it remains the gold standard for lofting and skinning in SketchUp. Here’s why it’s still fascinating. What does it actually do? In manufacturing, "lofting" means drawing a 3D surface by connecting 2D cross-sections. Curviloft automates this inside SketchUp. You select a series of profile curves, click a button, and— poof —a seamless, watertight mesh stretches across them. The "Three Pillars" of the Plugin Curviloft isn't one tool; it's three distinct genius moves: The "RBZ" Quirk (And Why You Care) You’ll

Imagine a curved pipe that changes shape—round on one end, square on the other. Curviloft morphs the shape smoothly along a drawn path. Perfect for custom moldings or roller coaster rails.
