work points, work axes, and work planes

Work Points, Work Axes,and Work Planes

• 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 Points

• 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

• Initiate a work axis

• Select two points on an object

• Points may be existing corners or midpoints

Work Axis Through Two Points

• Work planes– Continuous two-dimensional planes– Can be used to establish sketch planes– Assembly constraints can also be applied to

work planes

Work Planes

• Work plane can be placed on an existing part face

• Work plane feature is initiated

• Surface is selected

Applying Work Planes

• Initiate work plane feature

• Click, hold, and drag the cursor on an existing flat part surface

• Identify desired offset distance

Offsetting a Work Plane

• Create sketch plane and sketch geometry

Attaching a Sketch Plane

• 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)

Angled 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

Tangent Work Planes

• 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 Through a Cylinder

• 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
