Design View Representations
• Save configurations that show the assembly
in different states, stores the following
– Component visibility (visible or not visible)
– Component selection status (enabled or not
enabled)
– Color settings and style characteristics
applied in the assembly
– Zoom magnification
– Viewing angle
Design View Representations
•
•
•
•
•
Create New Design View Representation
Make Active
Rename
Lock
Public vs. Private Design Views
Design View Representations
• New Design View Representation
• Make Active – check mark
• Lock – view changes are not reflected in
locked Design View Representation
Design View Representations
• Set Design View when placing an
assembly file
– Options button
– Select Design View
Private Design View
Representations
• Same as a Public Design View
Representation buts creates an IDV file
• Should accompany assembly file
Drawings From Design View
Representations
• Select Representation from list
• Associative – Yes / No
Flexible Assemblies
• Set Flexible property to a subassembly to allow
movement independent from other occurrences
of the subassembly
Flexible Assemblies
• Right-click on the subassembly in browser or
graphics window and click Flexible from the
menu.
Positional Representations
• Create a motion study of an assembly
model
– Based on positional representation
Positional Representations
• Override Settings for an assembly
constraint
– Rename
– Override
Positional Representations
• Override Settings for an assembly
constraint
– Suppression
– Value
Positional Representations
• Edit Positional Representation
– Panel Bar
– Spreadsheet
Positional Representations
• Create Base Views based on Positional
Representation
Design View Representations
• Level of Detail
– Copy to Level of Detail
– Improve performance
Creating Overlay Views
• Overlay views document positional
representations of an assembly in a single
view.
Exercise 9-1
• Positional Representations
Capacity and Performance
• Improve the performance when creating
drawing files. Effect the preview of the
view and increase performance by reducing
what is displayed prior to view creation
– Application Options > Drawing tab
– Show Preview As
• All Components, Partial, and Bounding Box
• Section View Preview as Uncut
• Memory Saving Mode
Capacity and Performance
• Improve the performance when creating
drawing files. Effect the preview of the
view and increase performance by reducing
what is displayed prior to view creation
– Application Options > Drawing tab
– Use Bitmap for Shaded Views
• Always or Offline Only
• Image Fidelity
• Memory Saving Mode
– Preview Option
Capacity Meter
• Capacity meter shows
– Number of the left displays the number of
occurrences in the active file
– Number on the right displays the number of files in
the session.
– A memory graph or meter displays the amounts of
system RAM and amount of RAM that is free
– Options - Right-click a toolbar, select Customize
and then select the Toolbars tab
Levels of Detail Representations
• Improve capacity and
performance in modeling
and drawing
environments
– Suppress components
– Right-click on component
• Browser
• Graphics Window
Levels of Detail Representations
• In assembly file
– Expand Representations
folder
– Select required Level of
Detail
• Open existing assembly
– Click Options
– Select required Level of
Detail
Levels of Detail Representations
• Creating a drawing view of an assembly
select a Level of Detail Representation to
be used from the drawing view dialog
box.
Contact Detection Solver
• Determines how assembled components
behave when a mechanical motion is
applied
• Document Settings - Activate Contact
Solver
Contact Detection Solver
• Add components to set
– Browser
– Graphics Window
• Under constrained components
Contact Detection Solver
• Driven constraint
– Contact will drive under constrained
components that are in the Contact Set
Mirroring Components in an
Assembly
• Mirror assembly components or an entire
assembly in the current design file
• In an assembly click the Mirror
Components tool
Mirroring Components in an
Assembly
• Select a plane to mirror components
about
Mirroring Components in an
Assembly
• Select components to mirror and
select operation for each component
Mirroring Components in an
Assembly
• More area of the dialog box
– Reuse Standard Content and Factory Parts
– Preview Components
• Mirrored
• Reuse
• Standard Content
Mirroring Components in an
Assembly
• File Names
– Prefix
– Suffix
– Naming Scheme
Copying Components in an
Assembly
• Copy assembly components or an entire
assembly in the current design file
– Copy Components tool
– Select components in graphics screen or
Browser
Copying Components in an
Assembly
Select components to copy and select
operation for each component
Copying Components in an
Assembly
• File Names
– Naming Scheme
• Prefix
• Suffix
Exercise 9-2
• Mirroring Assembly Components
Assembly Work Features
• Create work planes and axes between
parts in an assembly by selecting edges
or points on parts.
• These work features remain tied to each
associated part and adjust accordingly as
the assembly is modified
Assembly Features
• Assembly features are features that are
defined in an assembly
• Only affect a part when the part is
viewed in the context of the assembly
• Assembly features only remove material
Assembly Sketched
• In an assembly sketch on a part’s:
– Face
– A part’s work plane
– An assembly work plane
Assembly Feature Tools
• Assembly
features exist
only at the
assembly level
• They do not
affect the
individual part
files
Assembly Feature
• Removing and Adding Participants
Exercise 9-3
• Creating Assembly Features
2D Design Layout
•
•
•
•
Function before form
Create a new part
Sketch 2D geometry
Add assembly constraints
Exercise 9-4
• Creating a 2D Design Layout
Content Center
• Library of standard components
• Place components while in an assembly
Content Center
• Publish feature to Content Center
• Publish components to Content Center
Design Accelerator
• Create complex parts and
features based on
engineering data such as
ratio, torque, power, and
material properties.
• The Design Accelerator
consists of:
– Component generators
– Mechanical calculators
– Engineer’s Handbook
