You need to model a transition piece for a modern pavilion – a circular skylight merging into a rectangular floor plan.
Select the rectangle, then the circle (hold Shift to select multiple). Open Curviloft > "Loft by Sections." curviloft plugin sketchup full
Draw a circle (top) and a rectangle (bottom) at different Z-heights. Ensure they are "Curves" (use Weld from LibFredo6). Without welding, Curviloft will think you have hundreds of tiny edges. You need to model a transition piece for
Introduction: Breaking Free from Flat Geometry For years, architects and 3D artists using SketchUp faced a common frustration: creating organic, double-curved surfaces, tensile structures, or smooth transitions between shapes felt nearly impossible. Native SketchUp tools excel at box modelling, but they struggle with lofting, skinning, and complex morphing. Ensure they are "Curves" (use Weld from LibFredo6)
A flawless, smooth morph surface that is fully editable.
