Create
- Loft
-
Skins a surface along a series of profile curves.
Select to set the Loft Options.
- Planar
-
Creates a planar (flat) surface within a boundary curve.
Select to set the Planar Options.
- Revolve
-
Sweeps out a surface by revolving a profile curve around a pivot point.
Select to set the Revolve Options.
- Birail
-
Creates a surface by sweeping between a series of profile curves along two path curves. The resulting surface can maintain continuity with other surfaces. The Birail Tool has options for sweeping 1, 2, or 3 (or more) cross sectional curves along the two path (rail) curves. The resulting surface is interpolated through the profile curves.
Select to set the Birail Options.
- Extrude
-
Creates a surface by sweeping a profile curve along a path curve.
Select to set the Extrude Surfaces Options.
- Boundary
-
Creates a surface by filling between boundary curves.
Select to set the Boundary Options.
- Square
-
Creates a four-sided surface by filling a region defined by four intersecting boundary curves. The resulting surface can maintain continuity with surrounding surfaces depending on the options set. In order for a square surface to be created, the four boundary curves must intersect, and you must select the curves in either a clockwise or counter-clockwise direction. You can ensure the curves intersect by snapping their end points to a common grid line, or by magnet snapping the end point of one curve to the end point of another.
Select to set the Square Options.
- Bevel
-
Creates beveled transition surfaces from a profile curve.
Select to set the Bevel Surfaces Options.
- Bevel Plus
-
Lets you create beveled transition surfaces with a much higher degree of control than regular Bevel.
Select to set the Bevel Plus Options.
Edit NURBS Surfaces
- Duplicate NURBS Patch
-
Creates new surfaces from the selected NURBS patches.
Select to set the Duplicate NURBS Patches Options.
- Align
-
Makes the edges of surfaces tangent or curvature continuous.
Select to set the Align Surfaces Options.
- Attach
-
Joins two surfaces together into a single surface.
Select to set the Attach Surfaces Options.
- Attach WIthout Moving
-
Attaches the selected curves or surfaces by reshaping their ends, rather than moving the objects.
- Detach
-
Splits a surface into multiple surfaces at the selected isoparms.
Select to set the Detach Surfaces Options.
- Move Seam
-
Moves the seam of a closed/periodic surface to the selected isoparm.
- Open/Close
-
Converts a surface between open and closed/periodic.
Select to set the Open/Close Surface Options.
- Intersect
-
Creates curves on surface wherever two surfaces intersect.
Select to set the Intersect Surfaces Options.
- Project Curve on Surface
-
Creates curves-on-surface by projecting a 3D curve onto a surface.
Select to set the Project Curve on Surface Options.
- Trim Tool
-
Hides parts of the surface defined by curves-on-surface.
Select to set the Trim Tool Options.
- Untrim
-
Undoes the last trim or all trims to a surface.
Select to set the Untrim Options.
- Extend
-
Extends an edge of a surface.
Select to set the Extend Surface Options.
- Insert Isoparms
-
Adds an edit point isoparm at the selected isoparm.
Select to set the Insert Isoparms Options.
- Offset
-
Creates a copy of the selected surface, offset a certain distance.
Select to set the Offset Surface Options.
- Round Tool
-
Creates rounded transition surfaces along the edges between existing surfaces.
Select to set the Round Tool Options.
- Stitch
-
Lets you stitch points, edges, or surfaces together.
- Select to set the Stitch Surface Points Options.
- Select to set the Stitch Edges Tool Options.
- Select to set the Global Stitch Options.
- Surface Fillet
-
Creates a fillet surface (Fillet Blend Tool), a circular fillet surface (Circular Fillet), or a fillet surface with configurable bias (Freeform Fillet) between two existing surfaces.
- Select to set the Circular Fillet Options.
- Select to set the Freeform Fillet Options.
- Select to set the Fillet Blend Tool Options.
- Sculpt Geometry Tool
-
Use this tool to sculpt NURBS, polygons, and subdivision surfaces.
For a description of the tool options, see Sculpt Geometry Tool Options.
- Surface Editing
-
Attaches a manipulator to the surface you click that lets you set the position and shape at arbitrary points on the surface.
Select to set the Surface Editing Tool Options.
- Booleans
-
Trims two surfaces to create the appearance of boolean operations.
Select to set the NURBS Boolean Options.
- Rebuild
-
Performs various operations on the selected surface.
Select to set the Rebuild Surface Options.
- Reverse Direction
-
Reverses or swaps the U and V directions of the selected surface.
