Parametric Modeling
Create parametric sketches, geometry, and PolyNURBS with construction history and variables.
- 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
  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.
  - 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.
- PolyMesh
  Create polymesh objects from other types of geometry and results.
- PolyNURBS
  Create free-form solid geometry that is smooth and continuous.
Implicit Modeling
Create implicit models with primitives, lattices, point clouds, fields, offsetting, Booleans, inverting, smoothing, morphing, and filleting.
Structures
Set up your model and run a structural analysis or optimization.
Motion
Set up and run a motion analysis, plot the results, and export the results.
Fluids
Prepare and run a computational fluid dynamics simulation.
Design Explorer
Evaluate designs by using geometric variables and applying a design-of-experiments (DOE) or optimization method. We recommend fully constraining your sketch when sketch variables are used in the design exploration.
Manufacture
Set up and run a basic porosity or thinning analysis.
Print 3D
Prepare and run an additive manufacturing simulation, and export a file for 3D printing.
Rendering
Adjust the materials and environment of objects in the scene to create a photorealistic image.
Inspire Python API
Learn how to access the Inspire Python API including online help, quick start demos, and the Extension Manager.

Export DXF/DWG

Export the current sketch as a .dxf or .dwg file.

Double-click a sketch entity to enter sketch edit mode.

Tip: You can also right-click a sketch and choose Edit or double-click a sketch in the Model Browser or History Browser to enter sketch edit mode.
On the Sketching ribbon, select the Export DXF/DWG icon.

Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
In the dialog box, select a folder, name your file, choose between .dxf or .dwg, and then click Save.
