**Work Points**• Work point • Independent entity • Location is defined in space • May be placed or projected onto part faces, linear edges, or onto an arc or circle • Can be constrained to center points of arcs, circles, and ellipses**Work Axis**• Work axis • Line extending forever in two directions • Useful for locating the center of a hole or cylinder • Used to create revolved features • May be constrained in assembly models**Work Axis Through Two Points**• Initiate a work axis • Select two points on an object • Points may be existing corners or midpoints**Work Planes**• Work planes • Continuous two-dimensional planes • Can be used to establish sketch planes • Assembly constraints can also be applied to work planes**Applying Work Planes**• Work plane can be placed on an existing part face • Work plane feature is initiated • Surface is selected**Offsetting a Work Plane**• Initiate work plane feature • Click, hold, and drag the cursor on an existing flat part surface • Identify desired offset distance**Attaching a Sketch Plane**• Create sketch plane and sketch geometry**Angled Work Planes**• Initiate work plane • Click on an EDGE • Select reference surface • Enter angle • Rotate angle CCW from reference surface**Angled Work Planes**• Angled work plane may be established by selecting two parallel EDGES**Angled Work Planes**• Angled work plane may also be established by selecting three corners or midpoints on an existing object(s)**Tangent Work Planes**• Select cylindrical surface close to area where work plane should be tangent • Identify original plane in origin folder that the new work plane should be parallel to**Work Planes Through a Cylinder**• Initiate a work axis • Select cylinder’s curved surface for placement • Initiate a work plane • Select work axis in cylinder • Select principle plane in origin folder and enter reference angle**Work Planes Through a Cylinder**• Initiate a work axis • Place it by selecting cylinder’s curved surface • Initiate work plane • Select work axis in cylinder • Select a principle plane in the origin folder and enter a reference angle**Work Planes Between Work Planes**• Create work plane through two parallel edges • Offset second work plane an appropriate distance away • Create third work plane between the first two by selecting both in any order
