Work Planes
A work plane is a flat plane extending infinitely in all directions along one
plane. A work plane is similar to the default origin YZ, XZ, and XY planes.
However, you create the work plane as needed, using existing features, planes,
axes, or points to locate the work plane.
Use a work plane to:
■ Create a sketch plane when no part face is available to create 2D sketched
features.
■ Create work axes and work points.
■ Provide a termination reference for an extrusion.
■ Provide a reference for assembly constraints.
■ Provide a reference for drawing dimensions.
■ Provide reference for a 3D sketch.
■ Project into a 2D sketch to create curves for profile geometry or reference.
The following illustrations show some of the methods you can use to define
a work plane.
Work Axes
A work axis is a straight vector extending infinitely in two directions. A work
axis is similar to the default origin X, Y, and Z axes, however, you create the
work axis as needed, using existing features, planes, or points to locate the
work axis.
Use a work axis to:
■ Create work planes and work points.
■ Project into a 2D sketch to create curves for profile geometry or reference.
■ Provide a line of rotation for a revolved feature.
