Parametric Modeling
Create parametric sketches, geometry, and PolyNURBS with construction history and variables.
- Construction History
  View and edit the construction history of your model.
- 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.
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.

Pave

Use the Pave tool to create faces manually on an existing object.

You can also use this tool to:

Blend two PolyNURBS surfaces
Close holes in PolyNURBS geometry
Convert PolyNURBS surfaces to solids

Pave an Optimized Shape

Pave a surface by placing points along the contour of an optimized shape.

You must have an optimized shape to pave. Note that the Pave tool only works on quads.

On the PolyNURBS ribbon, select the Pave tool.

Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
Select points, reference points, or edges to define a rectangle. A PolyNURBS surface is automatically created
To add another face to the PolyNURBS surface, click an open edge on the surface, and then place two more points.
Note:
- Ctrl-click in space with the Pave tool to use the nearest global plane.
- Ctrl-click a reference axis or plane reference to select the reference. While the reference is selected, all points you click snap to the axis or plane. Ctrl-click the reference axis or plane again to deselect it.
Repeat the process to pave additional surfaces.
Right-click and mouse through the check mark to exit, or double-right-click.
