Surface

Five groups, left to right.

Sweeps

• Add a Picture PlanePlaces a reference image on a plane.
• Sweep 1 RailSweeps a profile along a single rail curve.
• Sweep 2 RailSweeps a profile along two rail curves.
• Curves On 1 RailDistributes profile curves along one rail, ready to sweep.
• Curves On 2 RailsDistributes profile curves between two rails.

Create

• CornersA surface through three or four corner points.
• RectangularA flat rectangular plane.
• Rectangular Plane: 3 PointsA plane placed by three picked points.
• EdgesA surface from two, three or four edge curves.
• LoftA surface through a series of profile curves.
• PatchFits a surface through curves, points and meshes.
• RevolveRevolves a profile curve around an axis.
• DrapeDrapes a surface over objects like a sheet.
• Fit Plane Through PointsThe best-fit plane through picked points.
• Vertical PlaneA plane perpendicular to the construction plane.
• Cutting PlaneA plane through an object, sized to cut it.
• From Planar CurvesCaps planar closed curves with a surface.
• NetworkA surface from a network of crossing curves.
• BlendA smooth surface between two existing edges.
• Rail RevolveRevolves a profile along a rail curve.
• HeightfieldBuilds relief from the greyscale of an image.

Extrude

• Extrude CurveExtrudes a curve in a straight direction.
• Extrude Curve TaperedExtrudes with a draft angle.
• Normal to SurfaceExtrudes a curve normal to the surface it lies on.
• Extrude Curve to PointExtrudes a curve to a single apex.
• Extrude Curve Along CurveExtrudes a curve following a path curve.
• RibbonOffsets a curve and surfaces the gap between.

Edit

• FilletRounds the joint between two surfaces.
• Fillet Surface to Rail CurveFillets following a rail you pick.
• ChamferBevels the joint between two surfaces.
• ConnectExtends or trims two surfaces so they meet.
• OffsetCopies a surface at a set distance.
• ExtendLengthens a surface past its edge.
• Blend VariableA fillet whose radius changes along the joint.
• Fillet Surface to CurveFillets a surface up to a curve.
• Chamfer VariableA chamfer whose width changes along the joint.
• MatchMatches position, tangency or curvature at an edge.
• Variable OffsetOffsets by a distance that varies across the surface.
• MergeMerges two untrimmed surfaces into one.

Advanced

• Split and Refit SurfaceSplits a surface and refits the pieces.
• Divide Surface Along CreasesSplits a surface wherever it kinks.
• Surface TangentSets the tangent direction at a surface edge.
• Unroll Developable SurfaceFlattens a developable surface for cutting.
• Refit Surface to ToleranceRefits a surface within a given tolerance.
• RebuildRebuilds a surface with a set point count and degree.
• Convert to Single SpansRewrites a surface as single-span patches.
• Shrink Trimmed SurfaceShrinks the untrimmed surface under a trim.
• SmashFlattens a surface even when not developable.
• Flatten SurfaceFlattens a surface into the construction plane.
• Adjust Closed Surface SeamMoves the seam of a closed surface.
• Rebuild EdgesRestores surface edges to their true geometry.
