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.
- 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.
  - Editing PolyNURBS
    Edit vertices, edges, and faces to modify the shape of a PolyNURBS object.
  - Primitive
    Use the Primitive tools to create a single PolyNURBS solid or surface, either around a selected object or as the starting point for a new model. This is the tool you should start with if you want to build PolyNURBS geometry without wrapping or paving.
  - Fit
    Use the Fit tool to automatically create a new PolyNURBS part on top of existing geometry.
  - Wrap
    Use the Wrap tool to quickly wrap a PolyNURBS solid around an optimized shape. You can create multiple PolyNURBS cages, and bridge the face of one cage to another. You can also wrap a hole or negative space.
  - Pave
    Use the Pave tool to create faces manually on an existing object.
  - Move Bodies
    Use the Move Bodies tool to translate, rotate, or align PolyNURBS bodies.
  - Mirror Bodies
    Use the Mirror Bodies tool to mirror PolyNURBS bodies across a symmetry plane.
  - Add/Remove (+/-)
    Use the Add(+) and Remove(-) tools to modify an existing PolyNURBS cage by adding or removing blocks. This allows you to quickly build the basic shape of a PolyNURBS object.
  - Split
    Use the Split tools to split a cage with a loop or split a single PolyNURBS cage face.
  - Bridge
    Use the Bridge tool to create a bridge between two or more faces of either the same PolyNURBS cage or different cages.
  - Sharpen
    Use the Sharpen tool to control sharpness along the edges of a PolyNURBS. Four levels of sharpness are available, and you can set the sharpening factor manually or automatically.
  - Repair
    Use the Repair tool to close a hole in a PolyNURBS cage.
  - Shell & Offset
    Use the PolyNURBS Shell & Offset tool to offset the vertices of PolyNURBS part bodies and optionally shell the bodies by connecting copied offsets.
  - Shape Variable
    Use the Shape Variable tool to define which directions PolyNURBS cage points can move during PolyNURBS optimization.
  - Subdivision Surface
    Convert a PolyNURBS part to a subdivision surface for faster exit from PolyNURBS tools.
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.

Bridge

Use the Bridge tool to create a bridge between two or more faces of either the same PolyNURBS cage or different cages.

On the PolyNURBS ribbon, select the Bridge tool.

Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
Click two or more faces.
Click the selected faces to create the bridge.
Repeat the process to create more bridges. Right-click and mouse through the check mark to exit, or double-right-click.

Tip:

Merge two coincident faces by box selecting them and then using the Bridge tool. This technique works well with mirrored parts. You can also use this tool to create a tunnel.
You cannot create bridge between two different PolyNURBS parts created at two different points in the construction history timeline. You can, however, edit an existing PolyNURBS construction feature, continue adding PolyNURBS bodies, and then bridge between the bodies instead.
