  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 • Create Skeletal Models • Use the Frame Generator • 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. Creating Overlay Views • Overlay views document positional representations of an assembly in a single view.

  18. Exercise 9-1 • Positional Representations

  19. 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

  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 • Memory Saving Mode • Shaded Views • Always or Offline Only • Image Fidelity • Preview Option

  21. 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 click the Toolbars tab • Physical Memory option is the only option available in Vista

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

  23. 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

  24. 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.

  25. Assembly Substitution - Level of Detail Representation • Remove detail from a part or an assembly • Derive Assembly • Select Part File

  26. Assembly Substitution - Level of Detail Representation • Derive Assembly • Create a New Substitute with the Derive Assembly option • Derive a Subassembly with desired options

  27. Assembly Substitution - Level of Detail Representation • Select Part File • Create a part with same orientation • Create a New Substitute with the Select Part File option

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

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

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

  31. 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

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

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

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

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

  36. 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

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

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

  39. Exercise 9-2 • Mirroring Assembly Components

  40. 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

  41. Assembly Work 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

  42. Assembly Work Features • In an assembly sketch on a part’s: • Face • A part’s work plane • An assembly work plane

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

  44. Assembly Feature • Removing and Adding Participants

  45. Exercise 9-3 • Creating Assembly Features

  46. Skeletal Modeling • Source • .IPT file • Create a new IPT into an Assembly • Derive Component • Create geometry based on derive part

  47. Exercise 9-4 • Creating a Skeletal Model

  48. Frame Generator • Create frame structures • Skeleton part (modeling)

  49. Frame Generator • Steps to create frame • Create skeleton part that consists of a single sketch • Place members using the edges of the skeleton part • Members inserted from the frame generator • Add end treatments; miters and had holes etc.

  50. Frame Generator • Steps to Publish a Standard Part • Create a part file based on the required standard • Sketch, constrain, and dimension a sketch as needed • Create a work plane with an offset of zero based on the origin plane that the sketch was drawn on. • Create a work plane that is offset from the work plane created in step 3 • Create a parameter named Base_Length • Exrude sketch between work planes with From To option and use Base_Length parameter for distance • Publish part
