- Sketching
  Create and edit 2D parametric sketch geometry.
  - Introduction to Sketching
    Learn about sketching basics including the sketch plane, legend, constraints, context menu options, and construction geometry.
    - Sketch Plane
      Select a sketch tool, then select a sketch plane to begin sketching.
    - Sketch Legend
      The Sketch Legend in the upper left corner of the modeling window indicates whether a sketch entity is Projected or Intersected, and whether a sketch curve is Underdefined, Fully Defined, or Overconstrained.
    - Sketch Constraints
      Apply geometric relationships such as tangency and perpendicularity to sketch curves.
    - Sketch Context Menu Options
      Create a sketch imprint, remove constraints, align axes, convert sketches to construction geometry, and show or hide grids, points, constraints, construction lines, dimensions, or intersection curves.
    - Construction Geometry
      Construction geometry is used as a reference to line up or define other geometry.
    - Sketch Units
      All sketch data and parameter entities are handled according to the current unit system. All dimension values, variable manager values, and sketch entity data like line length, circle radius, or point position are appended with the current units system.
  - Variables
    Create and assign variables to parameters when modeling.
  - New Sketch
    Start a new sketch and select a sketch plane.
  - Project
    Project selected geometry onto the sketch plane as construction geometry.
  - Intersect
    Extract curves resulting from the intersection of the sketch plane with selected parts.
  - Point/Lines
    Sketch and edit a point, line, polyline, or line-arc.
  - Rectangles
    Sketch and edit a rectangle.
  - Polygons
    Sketch and edit a parallelogram or a regular polygon.
  - Circles
    Sketch and edit a circle.
  - Ellipses
    Sketch and edit an ellipse or an elliptical arc.
  - Arcs
    Sketch and edit an arc.
  - Splines
    Sketch and edit a spline.
  - Dimension
    Use the Dimension tool to define and/or constrain the dimensions of a sketch.
  - Transform
    Translate or rotate sketch entities.
  - Trim/Break
    Trim or split a sketch curve.
  - Extend
    Extend or shorten an entity of a sketch curve.
  - Fillet
    Round the corners of 2D sketch curves to create fillets with the same radius or different radii.
  - Offset/Mirror
    Offset or mirror a sketch curve.
  - Pattern
    Create a linear or circular pattern of sketch entities.
- Geometry
  Create, edit, and cleanup 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.

Sketch Plane

Select a sketch tool, then select a sketch plane to begin sketching.

A sketch plane can be a global plane, a user-created reference plane, or a planar face of an existing part.
