    Use the Ruled tools to create surfaces/solids by interpolating lines and surfaces either linearly or smoothly.
  - Faces
    A face is a single Non-uniform Rational B-Spline (NURBS) and is the smallest area entity. It has a separate underlying mathematical definition, specified when it was created.
  - Extrude/Revolve
    Use the Extrude/Revolve tool to drag and spin lines, surfaces, and nodes in order to create surfaces or solids.
    - Extrude Geometry
      Extrude lines, nodes, surfaces, elements, or facets along their normal direction, a vector, or another line.

    Use the Midlines tool to create midlines from existing lines, surface edges, or tube solids.
  - Extract Entities
    Use the Extract tool to convert sketches into geometry lines and surfaces with the realize option. Delete lines and surfaces converted from a sketch entity with the unrealize option.
  - Ribs
    Use the Ribs tool to create and modify simple ribs between two surfaces.
  - Create and Edit Feature Edges
    Use the Feature Edges tool to create and edit mesh controls on an edge.
- Edit Topology
  Explore the tools used to edit topology.
- Use Parasolid
  The Use Parasolid option, found in multiple Topology tools, helps you in creating/editing geometries using a parasolid geometry modeling kernel.
FE Geometry
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Meshing and Elements
Explore the different types of mesh you can create in HyperMesh and create and edit 0D, 1D, 2D, and 3D elements.
Model Build and Assembly
Create, organize and manage parts and subsystems.
Composites
HyperMesh composites modeling.
Connectors
Create connections between parts of your model.
Morph
Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality.
Skeleton Modeling
Create a reduced ordered model to facilitate optimization at the concept phase.
Design Space
Workflow to support topology optimization model build and setup.
Optimization
Setup an Optimization in HyperMesh.
Design Explorer
Multi-disciplinary design exploration and optimization tools.
Validate
Validate the model built before running solver analysis.
Analyze
Models require loads and boundary conditions in order to represent the various physics and/or physical equivalents to bench and in-use testing.
Axisymmetry
Reduce a full 3D model with axisymmetric surfaces while accounting for imperfections.
Concept Modeling
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing parts. The current capabilities are focused on stiffening parts.

Revolve Geometry

Revolve surfaces, nodes, lines, elements, or facets around a defined axis.

From the Topology ribbon, Extrude/Revolve tool group, click the Revolve tool.

Figure 1.

Optional: On the guide bar, click

to define additional options.

Tip: Click

to define the Biasing method and Biasing intensity for the element/facets selection.

Figure 2. No Biasing	Figure 3. Linear Biasing
Figure 4. Exponential Biasing	Figure 5. Bellcurve Biasing

Choose between Surfaces, Nodes, Lines, Elements, and Facets using the guide bar selector.
Select surfaces/nodes/lines/elements/facets in the modeling window.
Click Axis on the guide bar.
Left-click to place the axis.
Revolve your selection by dragging the slider or entering an angle in the microdialog.

Tip: Click in the microdialog to define the direction of the axis using the Vector tool. Once a direction has been defined, press Esc.
Enter the density value in the microdialog for elements / facets selection to Specify the number of elements to generate along the path of the revolve.
Check Create mesh to automatically open the 2D meshing tool after creating surfaces. After you finish meshing, exit the tool to return to Geometry.
On the guide bar, complete one of the following:
- Click to apply and stay in the tool.
- Click to apply and close the tool.
- Click to exit the tool without applying.

Note:

For the nodes input, based on the geometry creation mode defined, either a CAD surface or an FE geometry surface is created. While using the Revolve tool for lines or surfaces, the input determines whether a CAD surface or an FE geometry surface is created. For example, CAD lines are created as CAD surfaces, FE geometry edges are created as FE geometry surfaces.
FE geometry solid creation for elements/facets selection is not supported at this time.
A revolve preview for FE geometry solids is not supported at this time.
