New Meshing Tools

A variety of quad mesh tools were introduced to support subdivision modeling. The new tools are located in the mesh tool palette accessible from the main tool window. The introduction of quad meshes to Shark provides a suite of tools that enables an alternative conceptual design process based on mesh modeling. One of the advantages of mesh-based modeling is that models can be quickly pushed or pulled into complex shapes, whereas precision solids have some limits in what you can push or pull. The tools introduced provide options to create mesh primitives, skins, covers, revolutions, fill holes, and create bridges. These tools are suitable for subdivision modeling techniques.

Extensive Surface Tools

Shark supports nine surface types that are created by referencing curves. From left to right across the surface tool palette they are:

Extensive Surface Tools

Surface Tools

  • Infinite Plane: The Infinite Plane Surface is the simplest surface supported by Shark. An infinite plane is defined by a location and normal. The plane surface is useful for generating cross- sections through meshes, surfaces or solids
  • Net: The Net Surface is created from a collection of m x n curves. The curves may be combinations of lines, splines, arcs, ellipses, conics or circles. Each curve must be a single curvature continuous curve. No groups (composited curves) are allowed. A point is allowed at either the start or end of the surface. The supplied curves do not need to be planar and do not need to touch.
  • Ruled and Skin: A Ruled Surface has straight spans between each section. Sections can be of any curve type. This tool is available from the sub-tool palette. A Skin Surface fits a network of NURBS patches to a collection of curve cross sections. The curves can either be all opened or all closed.
  • Cover: The Cover Surface is an extremely versatile and powerful utility for creating a surface from curves connected end to end. Curves suitable for cover surfaces include arcs, circles, lines, splines, ellipses, and conics. Curves are not required to be in a plane.
  • Revolution: The Surface of Revolution is used to model axis symmetric objects. The designer can choose from one of two methods:

    • Revolve About 2 Points
    • Revolve About Curve
  • Extrude: The Sweep Two Points surface sweeps a curve, collection of curves or group along two user supplied points that define the direction and length of the sweep.
  • Swept: The One Rail Sweep Surface sweeps a curve, collection of curves or group along a user supplied rail curve. The resulting surface is associative to both the path and sweep curve. Modifying either will automatically update the associative sweep surface.
  • Bi-rail: The Two Rail Sweep Surface tool creates a swept surface by sweeping an open or closed curve between two rail curves. The rail curves define the orientation and scale of the surface as it moves between the two curves.
  • Tube:
    Creates a tube or pipe surface along a curve with a given radius.

Fill & Cap Surfaces

Shark's unique fill and cap surfaces provide a means to create tangent continuous surfaces suitable for repairing and stitching surfaces into solids.

Fill & Cap Surfaces Fill & Cap Surfaces Fill & Cap Surfaces

Thicken Surfaces

Precisely offset complex surfaces into a solid by using the thicken tool. The thicken tool also allows the user the choice to thicken a specific face or the entire solid.

Thicken Surfaces Thicken Surfaces

Stitch/Repair/Heal Surfaces into Solids

The Stitch tool provides a way to stitch, or sew, separate surfaces together to make a solid body that is topologically complete.

Stitch collections of individual surfaces into water-tight volumes. Utilize options that repair and heal less than perfect connections.

Stitch/Repair/Heal Surfaces into Solids

G1/G2 Edge Modeling

The Match Surface tool modifies the surface continuity at a given edge to a referenced edge.

Match surface continuity between shared surface edges.

G1/G2 Edge Modeling

Surface Analysis

The Verify: Surface Analysis: Zebra plot is very useful in combination with the Match Surface tool. The Zebra Plot helps visualize continuity between two surfaces.

Visualize surface quality using zebra, curvature, and environmental maps.

Surface Analysis

Associative Surface Modeling

Surfaces are associative to the original curves and parameters used to create the surface. Changing the curve will automatically change the dependent surface.

Associative Surface Modeling

Multiple Creation Methods

Create solids from a diverse collection of tools that include primitives, profiles, or features. Edit solids using associativity, parameters, history tree or direct editing.


Primitives are simple shapes defined by linear or quadric geometry. Shark supports spheres, blocks, cylinder, cones, torus, prisms, pyramids, ellipsoid, and slabs.

Choose any of the nine different solid primitive types to create quick simple shapes. Modify at any time using parameters such as width, height and length.

Primitives Primitives

Primitives tools: spheres, blocks, cylinder, cones, torus, prisms, pyramids, ellipsoid, and slabs

Profile Based Solids

A profile is a closed 2D section created from curves, lines or polygons. The curves must lie in the same plane. A 2D profile can be lathed, swept, extruded or sectioned to create a solid.

Create a solid from collections of curves by extruding, sweeping, or lathing. Modify one of the original curves and the solid with update.

Profile Based Solids

Solids tools: lathe, extrude, one rail sweep, two rail sweep, cutout, protrusion, skin, pipe, branched

Lathe Solid

The Lathe Solid command rotates any closed 2D polyline, circle, ellipse, closed spline or polygon. You can also lathe groups of closed curves.

Extrude Solid

The Extrude Solid command takes a profile and extends the shape a user specified distance. You can extrude 2D polylines, circles, ellipses, closed splines, and polygons. There are five extrude methods.

Lathe Solid
Extrude Solid

Solid Extrude

G1 Edge Blending

Smooth edges or faces using state-of-the-art blending technology. Apply constant, variable, fixed, or hold lines.

G1 Edge Blending


The Shell tool allows you to select faces to leave open. If no faces are selected, the part is hollowed inside.

Hollow a part and keep select faces open. Modify individual faces for specific thickness values.


Split 3D Part

The Split Solid command divides a solid into two components. The Split Solid command is useful for displaying solid sections in drawings and for creating large stereo lithography models.

Provide further clarity to your part designs by splitting or trimming away portions that hide key design features. Split your part with complex shapes such as cutting planes, NURBS, or other parts.

Split 3D Part

Split Solid with a Surface (and moved)

Local Face Editing

Directly edit faces of solids independent of previous construction history. Remove, translate, replace, match, or offset faces of part. Great for working with parts designed from other CAD systems such as AutoCAD®, Pro/E™, or SolidWorks®.

Local Face Editing

Feature Tree

Examine the construction history of a part with Concept Explorer. Suppress, remove, or access parameters through the construction of the part.
