• On Pont– Work Point– Positioned to an axis,

edge or work plane

Exercise 4-2

• Creating Holes

Shelling• Shelling

– Thin walls (thickness)

Shelling

Exercise 4-3

• Shelling a Part

Work Features• Work Features

– Special construction features

– Help position & define new features

– Parametrically attached– Types

• Work Planes• Work Axes• Work Points

– Different situations

Work Axis• Creating a Work Axis

– Acts like a construction line

– Infinite in length

– Axis of rotation

– Create a Work Axis• Filtered Options – Only select data that fits

the selected option

Exercise 4-4

• Creating Work Axes

Work Points• Creating Work Points

– Point • Filtered Options – Only select data that fits the

selected option

– Grounded Work Point• Positioned in 3D space

• Not associated

• Remains in the specified location

– 3D Move/Rotate dialog box

Work Planes• Creating Work Planes

– Understand when you need to create a work plane

– Rectangular plane– Parametric – Larger than the part– Edited and deleted like any

other feature– Filtered Options - Only select

data that fits the selected option

Work Planes• Types of Work Planes

• Parallel to Plane through Point• Midplane between Two Parallel

Planes• Midplane of Torus• Angle to Plane around Edge• Three Points• Offset from Plane• Two Coplanar Edges

• Tangent to Surface through Edge

• Tangent to Surface through Point

• Tangent to Surface and Parallel to Plane

• Normal to Axis through Point• Normal to Curve at Point

UCS User Coordinate System• Use like a work plane• Place on existing geometry• Position with absolute coordinates• No limit to the number of UCSs• Constrain UCS to UCS• Contains

– 3 planes– 3 Axes– Center point

Feature Visibility• Control visibility of

– Planes– Axes– Points– Construction surfaces– Sketches– UCS– Turn off visibility of individual objects

Exercise 4-5

• Creating Work Planes and a UCS

Patterns•Patterns

–Duplicate the feature multiple times

–Distance or angle–Types

• Rectangular and circular

–Suppressed–Child - parent relationship–Editing

Patterns• Rectangular Patterns

– Rectangular pattern dialog box

• Direction 1• Direction 2

– Options - More button• Start• Termination• Orientation

Patterns• Linear Pattern

– Pattern Along a Path• Helix, ellipse, spline,

series of curves• 2D or 3D

Patterns• Circular Patterns

– Circular Pattern dialog box

• Placement• Creation Method• Positioning Method• Flip

Exercise 4-6

Applying Your Skills

Skill Exercise 4-1 Skill Exercise 4-2

Checking Your Skills1. True__ False__ When creating a fillet feature that has more than one selection set, each selection set

appears as an individual feature in the browser.2. In regard to creating a fillet feature, what is a smooth radius transition?3. True__ False__ When you are creating a fillet feature with the All Fillets option, material is removed from

all concave edges.4. True__ False__ When you are creating a chamfer feature with the Distance and Angle option, you can

only chamfer one edge at a time.5. True__ False__ When you are creating a hole feature, you do not need to have an active sketch.6. What is a Point, Center Point used for?7. True__ False__ A part may contain only one shell feature.8. True__ False__ The only method to create a work axis is by clicking a cylindrical face.9. True__ False__ You need to derive every new sketch from a work plane feature.10. Explain the steps to create an offset work plane.11. True__ False__ The options for creating work features filter out geometry that is not valid for the selected

option.12. True__ False__ You cannot create work planes from the default work planes.13. True__ False__ A UCS can only be placed on existing geometry.14. True__ False__ When you are creating a rectangular pattern, the directions along which the features are

duplicated must be horizontal or vertical.15. True__ False__ When you are creating a circular pattern, you can only use a work axis as the axis of

rotation.
