Skinning is ideal for landscape architecture, organic roofs, and filling in complex holes within an existing mesh.
Navigate to Extensions > Extension Manager (or Window > Extension Manager depending on your SketchUp version).
This is the most common use case for creating smooth, organic transitions between separate shapes. curviloft rbz
For architects, interior designers, and 3D modelers using SketchUp, creating complex organic shapes can be a challenge. Standard SketchUp tools excel at planar, rectilinear forms, but struggle with curves, surfaces, and complex geometries. This is where —installed via an .rbz file—becomes an indispensable tool.
This is the most common use case. You select a series of separate contours (ribs), and the plugin "stretches" a skin over them. It is perfect for boat hulls, airplane wings, or organic furniture. Skinning is ideal for landscape architecture, organic roofs,
: Creates a surface bounded by 3 or 4 contiguous contours, which is ideal for modeling complex roofs, tents, or tensile structures. The SketchUp Essentials Installation Requirements To use Curviloft, you must install two separate
If you have ever struggled to create complex, organic, or double-curved surfaces in SketchUp, you have likely heard whispers of a legendary plugin: . For years, Curviloft has been the go-to extension for architects, 3D modelers, and woodworkers who need to generate skins, membranes, and solid geometry from simple linework. For architects, interior designers, and 3D modelers using

This article will serve as your complete encyclopedia for everything related to —from finding the legitimate file and installing it, to mastering its three core tools (Loft by Splines, Loft along Path, and Skin Contours).
While in preview mode, you can change the vertex matching property (e.g., No Interpolation , Aspect Ratio , or Subdivision ). If your mesh looks pinched, cycling through these properties usually fixes the issue. Conclusion
