What type of geometry can be used to create lofts?

Lofts in SolidWorks are generated by connecting multiple 2D shapes or profiles along a defined path. These shapes or profiles can be created using sketches, which consist of 2D geometry like lines, arcs, and curves.

When performing a loft operation, the user typically selects two or more sketches, and SolidWorks interpolates a new surface or solid within the defined profiles. Sketches serve as the fundamental building blocks for the loft features, allowing for versatile design possibilities with varying shapes and sizes.

While points, surfaces, and model edges can play roles in the broader design process, sketches are the specific elements used to define the loft's geometry. Points can define locations within the sketches, surfaces can be created afterward, and model edges may contribute to the overall design context, but it is the sketches that directly provide the necessary geometry for lofting.
