  1. Chapter 9Advanced Assembly Modeling Techniques

  2. Chapter 9 - Objectives • 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

  3. Chapter 9 – Objectives - Continued • 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

  4. 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

  5. Design View Representations • Create New Design View Representation • Make Active • Rename • Lock • Public vs. Private Design Views

  6. Design View Representations • New Design View Representation • Make Active – check mark • Lock – view changes are not reflected in locked Design View Representation

  7. Design View Representations • Set Design View when placing an assembly file • Options button • Select Design View

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

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

  10. Flexible Assemblies • Set Flexible property to a subassembly to allow movement independent from other occurrences of the subassembly

  11. Flexible Assemblies • Right-click on the subassembly in browser or graphics window and click Flexible from the menu.

  12. Positional Representations • Create a motion study of an assembly model • Based on positional representation

  13. Positional Representations • Override Settings for an assembly constraint • Rename • Override

  14. Positional Representations • Override Settings for an assembly constraint • Suppression • Value

  15. Positional Representations • Edit Positional Representation • Panel Bar • Spreadsheet

  16. Positional Representations • Create Base Views based on Positional Representation

  17. Design View Representations • Level of Detail • Copy to Level of Detail • Improve performance

  18. Creating Overlay Views • Overlay views document positional representations of an assembly in a single view.

  19. Exercise 9-1 • Positional Representations

  20. 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

  21. 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

  22. 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

  23. Levels of Detail Representations • Improve capacity and performance in modeling and drawing environments • Suppress components • Right-click on component • Browser • Graphics Window

  24. 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

  25. 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.

  26. Contact Detection Solver • Determines how assembled components behave when a mechanical motion is applied • Document Settings - Activate Contact Solver

  27. Contact Detection Solver • Add components to set • Browser • Graphics Window • Under constrained components

  28. Contact Detection Solver • Driven constraint • Contact will drive under constrained components that are in the Contact Set

  29. 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

  30. Mirroring Components in an Assembly • Select a plane to mirror components about

  31. Mirroring Components in an Assembly • Select components to mirror and select operation for each component

  32. Mirroring Components in an Assembly • More area of the dialog box • Reuse Standard Content and Factory Parts • Preview Components • Mirrored • Reuse • Standard Content

  33. Mirroring Components in an Assembly • File Names • Prefix • Suffix • Naming Scheme

  34. 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

  35. Copying Components in an Assembly Select components to copy and select operation for each component

  36. Copying Components in an Assembly • File Names • Naming Scheme • Prefix • Suffix

  37. Exercise 9-2 • Mirroring Assembly Components

  38. 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

  39. 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

  40. Assembly Sketched • In an assembly sketch on a part’s: • Face • A part’s work plane • An assembly work plane

  41. Assembly Feature Tools • Assembly features exist only at the assembly level • They do not affect the individual part files

  42. Assembly Feature • Removing and Adding Participants

  43. Exercise 9-3 • Creating Assembly Features

  44. 2D Design Layout • Function before form • Create a new part • Sketch 2D geometry • Add assembly constraints

  45. Exercise 9-4 • Creating a 2D Design Layout

  46. Content Center • Library of standard components • Place components while in an assembly

  47. Content Center • Publish feature to Content Center • Publish components to Content Center

  48. 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

  49. Applying Your Skills • Skill Exercise 9-1
