Work features are abstract construction geometry used when geometry is insufficient for creating and positioning new features. To fix position and shape, constrain features to work features.
On the ribbon, use the 3D Model tab Work Features panel Plane command to define a using feature , , , or other work features. Except in an assembly, you can create work planes when a work feature command requires you to select a plane. In an assembly, you can create a work plane between two parallel faces.
- A part face is not available as a sketch plane for sketching new features.
- An intermediate position is required to define other work planes (for example, at an angle to a face at an offset distance).
Work planes can be placed at any orientation in space, offset from existing faces, or rotated around an axis or edge. A work plane can be used as a sketch plane and dimensioned or constrained to other features or components. In an assembly, you can create a work plane between two planar faces on separate components.
In an , use the Plane command on the 3D Model tab to define work planes that reside in the assembly, not in a part model. You can create a work plane mid-way between planar faces of separate components, or on a single part while editing the part. are not selectable in an assembly.
Prior to the introduction of Direct Manipulation modeling techniques in Inventor R2011, the Plane command was the only method available to create work planes. This legacy method was, and still can be, used with one or more of the following relationships to define a work plane:
- On geometry (on three points, for example)
- Normal to geometry
- Parallel to geometry
- At an angle to geometry (on a plane and an axis)
