Loft Surface

Use the same Loft tool used in Loft Solid, then set bodyType to surface to blend between section profiles as an open surface instead of a closed solid. This is useful for fairings, covers, and transitional shapes that should remain editable as surface geometry rather than closing into a solid.

Body Type

The bodyType parameter controls whether Loft creates a solid body or a surface body. Set bodyType to surface when you want a shell with no thickness instead of a solid body. This is the same Body Type behavior described in the solid Loft workflow, the difference is simply that this surface page is focused on the surface output mode.

Selection

Choose a sketch segment when the surface should use a single edge as its profile. If the sketch forms a closed region, choose the region to use the full enclosed profile instead.

Other Parameters

All other Loft parameters, such as Sketches, Surface Degree (V-Direction), Bezier Approximation, Base Curve Index, and Start Tag / End Tag, work the same way as they do in Loft Solid. For the full parameter reference, visit the solid modeling section.

Zoo Design Studio writes KCL behind the scenes. A surface loft is just a loft call with bodyType = SURFACE, applied to multiple sketches.
