Avoid using 100-segment curves for simple shapes. High polygon counts slow down SketchUp's performance. Keep segment counts low; you can always use SketchUp’s native Soften/Smooth Edges panel later.
: This mode connects separate contours or faces using smooth splines. It is ideal for creating flowing, continuous shapes where each segment transitions naturally into the next.
Ensure the front faces (white) and back faces (blue/gray) of your curves match before lofting to avoid reversed and twisted geometry.
Select the tool, click on the curves in the order you want the surface to pass through them, and press Enter to generate the loft. curviloft plugin sketchup
Before committing to the geometry, a floating UI bar will appear at the top of your viewport. Here you can adjust:
Some users may prefer a manual method. This involves unzipping the downloaded file and copying the Fredo6_Curviloft.rb script and its corresponding folder into SketchUp’s Plugins directory (typically found in your Program Files or Application Support folder).
Curviloft operates through three distinct modeling modes, each represented by a unique icon on its toolbar:

Curviloft is a dedicated geometry generation extension for SketchUp developed by legendary plugin creator Fredo6. It generates surfaces based on networks of contours, rails, and guide curves. Instead of manually stitching faces together triangle by triangle, Curviloft automates the process, creating smooth, clean, and editable meshes in seconds. The Three Core Modeling Modes
Curviloft consists of three primary tools, each serving a distinct modeling function:
Joins separate, non-intersecting contour lines or curves sequentially. The geometry "stretches" from one profile to the next, acting like a digital fabric draped across a frame.
: Follows a designated path to create a 3D shape based on intermediate contours. Keep segment counts low; you can always use
Use the preview menu to modify the interpolation settings for smoother transitions. 3. Skinning
You create a 3D frame using 3, 4, or more connected edges. Curviloft analyzes the boundary and weaves a perfectly smooth patch across the empty space.
SketchUp is renowned for its intuitive, straightforward approach to 3D modeling, making it a favorite among architects and designers. However, its native toolset can sometimes struggle with complex, organic, or "curvy" shapes. This is where becomes an essential, if not indispensable, tool in any SketchUp user's arsenal.
: Use the Select tool to highlight the edges or contours you want to use. Activate Curviloft : Click one of the three Curviloft icons.
Review the preview mesh and adjust the interpolation settings for smoother transitions. Step 5: Click the checkmark to generate the final surface. 3. Mastering the Skinning Tool
This tool creates surfaces bounded by three or four contiguous contours. It is highly effective for "filling in" the spaces between complex frames to create a smooth, organic mesh. Key Features and Benefits Curviloft - SketchUcation
