Curviloft 18

Simpler than Loft by Splines – best for two identical-shape curves.

For those rendering in V-Ray or Lumion, CurviLoft 18 includes improved UV mapping algorithms. The surfaces generated no longer tear textures as frequently as they did in version 16 or 17.

If your loft creates wavy ripples where you wanted a flat panel, your input curves have uneven vertex counts. Use the "Rebuild Curve" feature (in CurviLoft’s right-click menu) to force all curves to have the same number of control points (e.g., 20 points each). This will create perfectly flat facets between curves. curviloft 18

If you are currently using CurviLoft 14, 15, or even 17, you might wonder if the jump to CurviLoft 18 is necessary. Here is the pragmatic breakdown:

Let's build a simple "Twisted Louver" façade—a classic impossible task in native SketchUp.

SketchUp 2021 and later introduced a new graphics pipeline. CurviLoft 18 leverages this for real-time previews. As you drag your mouse to adjust a loft, the surface updates instantly without the white "loading" flash.

The "Loft" function takes two or more profiles (curves) and creates a skin between them. CurviLoft 18 excels at handling mismatched vertex counts. If one curve has 4 points and another has 50, the algorithm automatically triangulates or quadrangulates the surface intelligently. For those rendering in V-Ray or Lumion, CurviLoft
