Geometry Modeling
Manage CAD, FE, and 2D parametric sketch geometry.
- Sketching
  Create and edit 2D parametric sketch geometry.
- Geometry
  Create, edit, and cleanup geometry.
  - Repair Geometry
    Review geometric errors in the model's surfaces and solids and fix any defects.
  - Create Geometry
    Explore the tools used to create geometry.
    - Points and Nodes
      Learn about creating, editing, and extracting points and nodes.
    - Lines
      A line represents a curve in space and is not attached to any surface or solid. A line is a one-dimensional geometric entity.
    - Midlines
      Use the Midlines tool to create midlines from existing lines, surface edges, or tube solids.
    - Shapes
      Create and edit circles and rectangles with the Shapes tool.
    - Surfaces
      A surface represents the geometry associated with a physical part. A surface is a two-dimensional geometric entity that may be used in automatic mesh generation.
    - Solids
      Solids are closed volume of surfaces that can take any shape. Solids are three-dimensional entities that can be used in automatic tetra and solid meshing.
    - Create Revolve Regions
      Use the Revolve tool to create axisymmetric revolved regions around select solid bodies. This is useful for creating regions around rotating bodies like fans, impellers, wheels, and so on.
    - Extract Midsurfaces
      Use the Midsurfaces tool to extract the midsurface of sheet metal stampings, molded plastic parts with ribs, and other parts that have thickness clearly smaller than width and length.
    - Extrude Geometry
      Extrude surfaces, nodes, or lines along their normal direction, a vector, or another line.
    - Create Ruled Surfaces and Solids
      Use the Ruled tools to create surfaces/solids by interpolating lines and surfaces either linearly or smoothly.
  - Edit Geometry
    Explore the tools used to edit geometry.
  - Geometry Cleanup
    Clean up problematic areas on geometry.
  - Simplify Region
    Use the Simplify Region tool to create simple shapes around selected geometry.
- Discrete Geometry
  Work with discrete geometry like FE Geometry and floating elements.
- Model Build and Assembly
  Create, organize and manage parts and subsystems.
Meshing
Generate surface/volume mesh by defining mesh controls, or interactively create and edit 2D surface mesh.
Setup
Prepare your model and run the simulation.
Post-Processing
Post-process the simulation results by creating visualizations and measurements.
Automation
Automate simulation processes with templates and utility scripts.
Design Exploration
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Solver Help
More resources for AcuSolve and ultraFluidX solvers.

Create Revolve Regions

Use the Revolve tool to create axisymmetric revolved regions around select solid bodies. This is useful for creating regions around rotating bodies like fans, impellers, wheels, and so on.

From the Geometry ribbon, click the Revolve tool.
