Curviloft 18 Page

Select multiple open or closed curves in sequence, and Curviloft will generate a smooth skin passing through all of them.

In the SketchUp 2018 ecosystem, Curviloft was widely used by architectural modelers, furniture designers, and organic modelers to create complex curved surfaces.

SketchUp is celebrated for its intuitive, push-pull simplicity. However, creating complex, organic geometries—such as sweeping car chassis, ergonomic furniture, or fluid architectural facades—can quickly reveal the software's native limitations. When straight lines and flat faces no longer suffice, 3D modelers turn to plugins.

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

If you are using modern versions of SketchUp and seeking the latest, most stable functionalities—often referred to as part of the updated ecosystem (which supports current iterations through 2024–2026, often updated via Curviloft 1.8x or later)—this guide will walk you through everything you need to know. What is Curviloft?

Whether you are a student modeling a futuristic pavilion or an architect conceptualizing a sweeping double-curvature facade, adding Curviloft 1.8 to your arsenal will permanently remove the barriers to complex 3D design. It remains one of the most celebrated and beloved plugins in the SketchUp ecosystem for a very good reason.
