Parametric Modeling
Create 2D sketches, surfaces, and solids 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.
  - Reference Geometry
    Create and modify reference planes, axes, or points.
  - Extrude
    Extrude profiles or 2D surfaces in one or two directions to create solids or 3D surfaces with optional end caps. Create a new part or combine, merge, subtract, or intersect the extruded shape with existing parts.
  - Revolve
    Revolve one or more faces, sketches, lines, or 2D edges about an axis.
  - Extract
    Extract selected geometry features and transfer them to a new part.
  - Sweep
    Sweep a profile along a path to create a solid or surface. Create a new part or combine, subtract, or intersect the swept shape with existing parts.
  - Multi Sweep
    Sweep multiple profiles along a path to create a solid or surface. Create a new part or combine, subtract, or intersect the swept shape with existing parts.
  - Pipe
    Create a pipe along one or more edges/lines. The pipe has a uniform cross section that can be circular, square, rectangular, or triangular.
  - Loft
    Create a solid loft or a lofted surface from profiles and guide curves. Create a new part from the loft or combine, subtract, or intersect the loft with existing parts.
  - Patch
    Fill in a missing surface.
  - Pattern
    Create a linear or circular pattern of parts or faces.
  - Mirror
    Mirror parts across a symmetry plane.
  - Rib
    Extrude rib geometry from a sketch to stiffen your model. You can select an arc, curve, straight line, or curved surface.
  - NURBS Curve
    Create a NURBS curve, which is a free-form curve.
  - Blend Curve
    Create a free-form curve that blends into one or more existing curves, surfaces, or edges.
  - Offset Curve
    Create a copy of one or more curves at a specified distance from the source curves. This tool can be used on both 2D and 3D curves.
  - Helix Curve
    Create a helix (or a spiral if the top and bottom radii are different).
  - Extend Curve
    Extend a curve and modify the shape of the extension.
  - Face Curve
    Extract curves from a face in the U or V direction. This is useful for creating trim curves that run along a face.
  - Divide Curve
  - Intersect Curves
    Split intersecting curves or wire bodies into several curves.
  - Simplify Curves
    Simplify one or more curves by changing the number of control points and inverting their sequence, joining multiple curves, or by applying an arc length parametrization.
  - From Surface Intersection
    Extract curves from the intersection of two surfaces.
  - Boolean
    Create a new part by using one set of solids to edit another set of solids.
  - Fillets
    Create fillets or chamfers along an edge.
  - Trim/Split
    Remove part of a surface or solid by projecting a profile curve onto it. Or use a set of tool surfaces to split a set of target surfaces.
  - Slice
    Slice a set of solid objects with a cutting plane or surfaces.
  - Intersect
    Retain only the intersecting portions of one or more parts.
  - Shell
    Remove material and create thin walls to generate a shelled part.
  - Draft
    Add draft to one or more faces of a part.
  - Push/Pull
    Push, pull, or revolve a face, sketch, line, or 2D edge to extrude it into a solid or surface, create or resize a hole, eliminate rounds, or modify wall thickness.
  - Extend Surface
    Extend a surface along one or more edges. You can extend the surface to a curve or another surface.
  - Offset
    Offset surfaces or parts, thicken surface parts and convert them to solids, or thicken and hollow solid parts.
  - Move Faces
    Translate, rotate, copy, or extend features.
  - Partition
    Divide a solid part into design and non-design regions by selecting a hole, pocket, or face to offset.
  - Simplify
    Clean up problem areas in the geometry of a model before running an analysis.
  - Delete Faces
    Delete faces from solid or sheet parts.
  - Close Holes
    Use the Close Holes tool to fill in missing surfaces, or to remake bad or problematic surfaces.
  - Midsurface
    Extract a midsurface or side faces from thin solids, and determine where surfaces are represented.
  - Scale
    Resize parts in your model, which is useful when working with an imported model that is associated with a different default unit system.
  - Tags
    Assign or query tags (metadata) that can be associated with one or more entities in a model.
  - Deform
    Twist, bend, taper, shear, stretch, or drape parts within a specified region (deformation zone).

Delete Faces

Delete faces from solid or sheet parts.

On the Geometry ribbon, select the Delete Faces tool.
Note: The tool may be hidden in the dropdown menu. To access the dropdown menu, you can do one of the following:
- Select at the lower right corner of the currently displayed tool.
- Click and hold the currently displayed tool.
Select one or more faces.

Note: To deselect, hold down Ctrl while clicking.

Selected faces are shown in red.
Select a red face to delete it, or click Apply on the guide bar to remove all red faces.
