# Surface

Surface Modeling provides unparalleled design freedom, making it essential for industrial aesthetic design. Surfaces bridge styling design and product engineering – designers create Class-A surfaces (zero-thickness geometry) that are delivered to engineering teams. Engineers then thicken surfaces into manufacturable structures. Iterative modifications via control points, curvature adjustment, or boundary edges offer greater flexibility than solid editing.

Primitive Surfaces

Extruded Surface
Revolved Surface
Planar Region

Advanced Surfaces

Swept Surface (with guide curves)
Lofted Surface (cross-section blending)
Filled Surface (boundary-driven)

Editing Operations

Trim Surface
Knit Surface (gap tolerance control)
Extend Surface
Offset Surface
Ruled Surface (tangency/curvature continuity)

Solid-Surface Conversion

Thicken (surface-to-solid)
Delete Face (solid-to-surface)
Cut with Surface
