**Work Points Work Axes**and Work Planes**Work Points**A work point is an independent entity whose location is defined in space. Work points may be placed or projected onto part faces, linear edges, or onto an arc or circle. Work points can be constrained to the center points of arcs, circles, and ellipses.**Work Axes**A work axis is a line that extends forever in two directions. Work axes are useful for locating the center of a hole or cylinder, are used in the creation of revolved features, and may be constrained to in assembly models.**Work Axis Through Two Points**• Initiate a work axis. • Select two points on an object. The points may be existing corners or midpoints.**Work Planes**Work planes are continuous two-dimensional planes that can be used to establish sketch planes. Assembly constraints can also be applied to work planes.**Applying Work Planes**To place a work plane on an existing part face, the work plane feature is initiated and the surface is selected.**Offsetting a Work Plane**• Initiate the Work Plane feature. • Click, hold, and drag the cursor on an existing flat part surface. • Identify the desired offset distance.**Attaching a Sketch Plane**Once a work plane is established, a sketch plane must be created on it in order to sketch geometry.**Angled Work Planes**• Initiate the work plane. • Click on an EDGE. • Select a reference surface. • Enter the angle. • The angle is rotated CCW from the reference surface.**Angled Work Planes**An angled work plane may be established by selecting two parallel EDGES.**Angled Work Planes**An angled work plane may also be established by selecting three corners or midpoints on an existing object(s).**Tangent Work Planes**• Select a cylindrical surface around the area where the work plane should be tangent. • Identify in the origin folder which original plane the new work plane should be parallel to.**Work Planes Through a Cylinder**• Initiate a work axis and place it by selecting the cylinder’s curved surface. • Initiate a work plane and select the work axis in the cylinder. • Select a principle plane in the Origin folder and enter a reference angle.**Work Planes Through a Cylinder**• Initiate a work axis and place it by selecting the cylinder’s curved surface. • Initiate a work plane and select the work axis in the cylinder. • Select a principle plane in the Origin folder and enter a reference angle.**Work Planes Between Work Planes**• Create a work plane through two parallel edges. • Offset a second work plane a given distance away. • Create a third work plane between the first two by selecting both in any order.
