Work features are abstract construction geometry used when current geometry is insufficient for creating and positioning additional features. To fix position and shape, you can constrain features to work features.
Use the Axis command to designate unconsumed sketch geometry, points, or a part edge as a work axis.
In a part file, work axes can be created in-line as input to other work feature commands.
You can create a work axis on the following types of geometry:
- A linear edge.
- A sketch line.
- A 3D sketch line.
- A line and plane to create a work axis coincident with the line projected onto the plane along the normal of the plane.
A work axis is a construction line of infinite length that is parametrically attached to a part.
In an assembly, a work axis is constrained relative to an existing component.
Work features include work planes , work axis , and work points . The work feature commands provide prompts to help you with selection and placement. The proper orientation and constraint conditions are inferred from the geometry you select and the order in which you select it.
Use work axes when creating features and assemblies to mark symmetry lines, centerlines, or distances between revolved feature axes.
In drawings, use work axes to mark locations of automatic centerlines and center marks.
You can also place work axes along the axes of circular features such as bosses, shafts, or holes. When placing components in an assembly, constrain them along work axes.
When creating 3D sweeps, you can place a work point at the intersection of work axes and work planes, and then select the work points to specify the sweep path.
