Sketchup - Curviloft Plugin

To use the Curviloft plugin for SketchUp effectively, you must understand its three distinct modes. Trying to use the wrong mode is the #1 cause of "red faces" and broken meshes.

The power of Curviloft lies in its parameters window, which appears after selecting geometry. Key parameters include:

This is the flagship feature. You select two or more cross-sectional curves (profiles), and Curviloft generates a continuous surface bridging them.

Rating: 9.2 / 10

Curviloft is a must‑install plugin for any SketchUp user who models curved or organic geometry. It transforms SketchUp from a “box‑making” tool into a capable surface modeler. The fact that it remains free is extraordinary given its power and reliability.

The only reasons not to install Curviloft are if you strictly model rectilinear architecture or if you’re unwilling to watch a 15‑minute tutorial. For everyone else – especially architects, designers, and 3D printing enthusiasts – Curviloft is non‑negotiable.

This is what most people think of when they hear "loft." You select a series of profiles (faces, edges, or curves) and hit "Skin."

How to use it:

Best for: Organic furniture, airplane fuselages, architectural columns, and terrain transitions.

This tool generates a surface by connecting a series of open or closed contours (curves). It is ideal for forms that change shape gradually from one profile to another, similar to a hull of a ship or a curved wall.

Curviloft is not just a plugin; it is a fundamental extension for anyone who needs to move beyond orthogonal modeling in SketchUp. While it requires an initial investment in learning, the ability to create complex, smooth, and editable surfaces unlocks a new realm of design possibilities. Combined with Fredo6’s other tools, it makes SketchUp a serious contender for freeform modeling—traditionally the domain of Rhino or Blender. To use the Curviloft plugin for SketchUp effectively,

Verdict: Essential for professional SketchUp users. Well worth the modest cost (donationware/paid license depending on version).

Note: Always download Curviloft from the official SketchUcation or Fredo6’s GitHub repository to ensure compatibility and safety.
