Curviloft is a dedicated lofting and skinning plugin for Trimble SketchUp. In 3D modeling, "lofting" refers to the process of stretching a 3D skin or surface over a series of guide curves or profiles.

This comprehensive guide covers everything you need to know about Curviloft RBZ, from installation to mastering its core features. What is Curviloft RBZ?

The is the essential installation package for one of SketchUp’s most powerful surface modeling extensions. Correct installation requires the companion library LibFredo6 and adherence to SketchUp’s RBZ installation process. When properly installed, Curviloft significantly expands SketchUp’s native organic modeling capabilities, making it a staple for architects, product designers, and 3D artists.

You select a closed loop of three or four separate interlocking edge curves. Curviloft treats these edges as a frame and stretches a virtual fabric mesh across the interior void.

: Creates surfaces based on a set of contours.

The practical applications of this plugin are vast and can dramatically improve your workflow across multiple disciplines:

Curviloft operates primarily through three distinct visual tools available on its dedicated toolbar. Each tool addresses a different organic modeling challenge by calculating geometry between isolated edges or contours.

A context-sensitive menu will appear at the top of your viewport. Here, you can adjust the vertex matching, increase segment density for a smoother curve, or change the interpolation style from straight lines to a smooth spline.

It scales, rotates, and morphs multiple profiles as they slide along a defined trajectory guide line.
