Transcript U5 Work Points, Work Axes, and Work Planes

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 twodimensional 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.
