After completing this chapter, you will be able to perform the following: –Create design view representations –Create flexible assemblies –Create positional representations –Create overlay drawing views –Improve assembly capacity and performance –Detect contact in assemblies –Mirror an assembly Chapter 9 - Objectives

After completing this chapter, you will be able to perform the following: –Copy an assembly –Create assembly work features –Create assembly features –Work with 2D components in assemblies –Locate tools related to the Content Center and Design Accelerator Chapter 9 – Objectives - Continued

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

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 Design View Representations

Same as a Public Design View Representation buts creates an IDV file Should accompany assembly file Private Design View Representations

Select Representation from list Associative – Yes / No Drawings From Design View Representations

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

Level of Detail –Copy to Level of Detail –Improve performance Design View Representations

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
