Introduction to Sketching
Learn about sketching basics including the sketch plane, legend, constraints, context menu options, and construction geometry.
Sketch Plane
A sketch plane can be a global plane, a user-created reference plane, or a planar face of an existing part.

Parametric Modeling
Create 2D sketches, surfaces, and solids.
- Construction History
  View and edit the construction history of your model.
- Variables
  Create and assign variables to parametrize a model. This allows you to quickly iterate and compare design concepts by tweaking the values of the variables.
- Global References
  Global references are the global origin, axes, and planes shown in the modeling window. They can be helpful when creating and defining your model.
- Sketching

    - Sketch Plane
      A sketch plane can be a global plane, a user-created reference plane, or a planar face of an existing part.
    - Underdefined, Fully Defined, and Overconstrained Sketches
      The Sketch Legend and Model Browser icons indicate whether a sketch curve is underdefined, fully defined, or overconstrained.
    - Projected or Intersected Sketches
      The Sketch Legend indicates whether a sketch entity is Projected or Intersected.
    - 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.
    - Select a Coincident Sketch Entity
      Select a coincident sketch entity to make precise modifications.
  - New Sketch
    Start a new sketch (S) 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 or surfaces.
  - Point/Lines
    Sketch and edit a point, line, polyline (L), or line-arc.
  - Rectangles
    Sketch and edit a rectangle (R).
  - Polygons
    Sketch and edit a parallelogram or a regular polygon.
  - Circles
    Sketch and edit a circle (C).
  - Ellipses
    Sketch and edit an ellipse or an elliptical arc.
  - Arcs
    Sketch and edit an arc (A).
  - Splines
    Sketch and edit a spline (S).
  - Dimension
    Use the Dimension tool (D) to define and/or constrain the dimensions of a sketch.
  - Transform
    Translate or rotate sketch entities.
  - Trim/Break
    Trim (B) 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 (F) with the same radius or different radii.
  - Offset/Mirror
    Offset (O) or mirror (M) a sketch curve.
  - Pattern
    Create a linear or circular pattern of sketch entities.
  - Export DXF/DWG
    Export the current sketch as a .dxf or .dwg file.
- Geometry
  Create and modify parametric surfaces and solids.
