Work Points Work Axes and Work Planes
3
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.
4
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.
5
Work Axis Through Two Points

• Initiate a work axis.
• Select two points on an object. The points may be
  existing corners or midpoints.

6
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.
7
Applying Work Planes
To place a work plane on an existing part face,
the work plane feature is initiated and the
surface is selected.
8
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.

9
Attaching a Sketch Plane
Once a work plane is established, a sketch plane
must be created on it in order to sketch geometry.
10
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.

11
Angled Work Planes
An angled work plane may be established by
selecting two parallel EDGES.
12
Angled Work Planes
An angled work plane may also be established by
selecting three corners or midpoints on an
existing object(s).
13
Tangent Work Planes

• Select a cylindrical surface around the area
  where the work plane should be tangent.
• Identify in the origin folder, what original
  plane the new work plane should be parallel to.

14
Work Planes Through a Cylinder

• Initiate a work axis and place it by selecting
  the cylinders 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.

15
Work Planes Through a Cylinder

• Initiate a work axis and place it by selecting
  the cylinders 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.

16
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 in between the first
  two by selecting both in any order.
