19. Shelling Shelling Thin walls (thickness)
Remove material (scooping out)
Hollow inside
Shell dialog box

20. Shelling Shelling Remove Faces Thickness Direction

Mid-plane
Unique Face Thickness
Different thickness
Specific face thickness
More button
Troubleshooting: In the case of shelling failures, first try reducing the thickness (much smaller value). Second: remove complex modeling features that can be applied later (such as variable radius fillets or complex fillets with corner blends)

21. Exercise 4-3
Shelling a Part

22. Work Features Work Features Special construction features
Help position & define new features
Parametrically attached
Types
Work Planes
Work Axes
Work Points
Different situations
In Line work features may also be created to assist in the construction of other work features such as work axes and planes (i.e. creating work points in the context of the work plane feature to help in construction)
This is also reflected in the Browser structure

23. 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
The 3d move/rotate tool in the graphics screen allows the user to directly interact with it. For most situations, the user should be able to use just the 3d move/rotate tool and the context menu to get the job done.
The 3d Move/Rotate functionality for grounded work points is only available in the Part Environment and not in the Assembly Environment (unless activating a part in place)
The increment in which the 3d tool snaps is set in the Document Settings -> Modeling tab

24. Exercise 4-4
Creating Work Axes

25. Work Points Creating Work Points Point Grounded Work 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
The 3d move/rotate tool in the graphics screen allows the user to directly interact with it. For most situations, the user should be able to use just the 3d move/rotate tool and the context menu to get the job done.

26. 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

27. 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

28. 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

29. Feature Visibility Control visibility of Planes Axes Points

33. Patterns Linear Pattern Pattern Along a Path
Helix, ellipse, spline, series of curves

39. Checking Your Skills
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.
In regard to creating a fillet feature, what is a smooth radius transition?
True__ False__ When you are creating a fillet feature with the All Fillets option, material is removed from all concave edges.
True__ False__ When you are creating a chamfer feature with the Distance and Angle option, you can only chamfer one edge at a time.
True__ False__ When you are creating a hole feature, you do not need to have an active sketch.
What is a Point, Center Point used for?
True__ False__ A part may contain only one shell feature.
True__ False__ The only method to create a work axis is by clicking a cylindrical face.
True__ False__ You need to derive every new sketch from a work plane feature.
Explain the steps to create an offset work plane.
True__ False__ The options for creating work features filter out geometry that is not valid for the selected option.
True__ False__ You cannot create work planes from the default work planes.
True__ False__ A UCS can only be placed on existing geometry.
True__ False__ When you are creating a rectangular pattern, the directions along which the features are duplicated must be horizontal or vertical.
True__ False__ When you are creating a circular pattern, you can only use a work axis as the axis of rotation.
