If you have ever looked at a complex shape and thought, "I can't do that in SketchUp," buy Curviloft 18a. An hour later, you'll be looking for excuses to loft everything—curtains, car bodies, alien spaceships, even your coffee mug.
Unlike subdivision modeling (which pushes and pulls a base mesh), Curviloft is a generative lofting tool. It is faster for creating:

She was standing in a room made of rib cages. The walls were bone-white lattices, and between them, light pulsed like slow blood. A voice spoke without words: You are not the first to lean into me. In the dream, she knew the building’s name. It was older than the permit records, older than the architect. It had been a hill once, then a root system, then a forgotten intention. The curving floors were not a flaw. They were the building’s memory of lying down. curviloft 18a
is a, released on Oct 31, 2018, is a maintenance release of the popular Curviloft extension for SketchUp, designed to add parametric surface generation to the modeling environment. While newer versions (like 2.0a) exist for the latest SketchUp releases, 18a is highly stable for users on older versions (2018-2020) and still utilizes the same foundational three-tool system.
One night, deep in winter, the elevator stopped humming. The silence woke her. She sat up in the tilted dark and felt the building hold its breath. A crack ran along the western wall—not a flaw, but a mouth. From it came a warm, earthen smell. And a whisper: Stay.
Version 18a introduced critical performance optimizations, smoother polygon distribution, and tighter integration with LibFredo6 (the shared library required to run Fredo6’s plugins). It remains a highly sought-after version for its balance of speed, predictability, and lightweight footprint on system memory.

The first week, she did fight it. She pushed her desk against the lowest wall, only to have her pens roll uphill overnight. She hung a mirror plumb-level, but it made the room look like it was tilting into a drain. She woke up sideways on the mattress, her pillow having migrated to the far end of the loft like a small, obedient animal.

It can generate geometry based on complex curves, allowing you to create organic shapes by simply drawing the contours first. 2. Loft Along Path

Using SketchUp's native or Bezier Spline tools, draw three or four curved lines floating parallel to one another in the air at varying heights. These will act as the "skeleton" of your canopy. Step 3: Activate Loft by Splines
