  4. Tons of Components Complex Components What is a LARGE Assembly?

  5. The items listed below are some of the more generic and underlining situations where large models can slow your performance. 3D Model Opening and Saving Slow Performance While Working in 3D Creating Drawing Views and Opening Drawings The Foundation

  6. First you must get the model opened within Inventor. This may sound simple but sometimes models take over an hour to open. 3D Model Opening File Open Time File Save Time File Display Time

  7. Once the model is open within Autodesk Inventor, now you need to work with it in a productive manner. Zooming and Rotating Model and Feature Edits Model Solving Slow Performance While Working

  8. Once you have the digital prototype 3D model you need to create manufacturing 2D drawings. Initial Drawing View Processing Time Updating and Editing View Time File Open and Save Time Zooming and Panning Performance Drawing View and Opening Drawings

  9. Let’s make sure you have the correct tool for the job. Computer Hardware Overview

  10. Benefits Faster processing during true 64-bit applications and processes. Direct access to more physical memory than 32-bit systems. (More then you can afford!!!) 64-bit Computing

  11. What you Need Computer with a 64-bit processor Microsoft 64-bit Operating System (XP or Vista Only) 4GB or more of physical memory 64-bit Computing + + =

  12. OpenGL or DirectX (3D) Windows Vista Contains DirectX 10 Windows XP Contains DirectX 9 Only Graphics

  13. Physical Memory (RAM)Make sure you buy enough (4GB or 8GB) Video CardPurchase middle of the road and make sure it is DirectX 10 Hard DriveGet at minimum a SATA 3.0Gb/s – transfer rate 3.0 bit/sec. ProcessorAll are great now so just make sure it supports 64-bit and is a multi-core processor of some type. Purchasing Recommendations

  14. Drawing Tab Display Line Weights Memory Saving Mode View Preview Display Show Preview As Application Options

  15. General Tab Undo File Size (768 MB Recommended) Enable Prehighlight Application Options

  16. Display Tab Display Quality Enabled Edge Display View Transition Time Minimum Frame Rate Application Options

  17. Occurrences and Documents Memory Usage Telemetry / Gauges

  18. Level of Detail representations provide a means to improve capacity and performance. They provide the ability to suppress unneeded components to reduce memory consumption and to simplify the modeling environment. Level of Detail

  19. “Master” Level of Detail Default representation that contains all components. “Medium” Level of Detail Custom representation that contains less components. Offload all items not required. “Low” Level of Detail Custom representation that contains the minimum components for space management only. Level of Detail (Master-Medium-Low)

  20. “Master” Level of Detail

  21. “Medium” Level of Detail

  22. “Low” Level of Detail

  23. The real power of this standardized method is when you start to have sub-assemblies. Nested Levels of Detail

  24. Utilize the various advanced selection tools within Inventor to aid with the creation of LOD’s. Component Selection Tools

  25. One of the best ways to utilize LOD representations is during the file open operation. (Reducing Memory) Utilizing Levels of Detail at File Open

  26. The amount of detail you put into your components control how “heavy” they are within large assemblies. Create different versions for different times. Component Simplification Low Detail 186 KB File Size Medium Detail 520 KB File Size Full Detail 1,146 KB File Size

  27. Part Simplification Examples Low Detail 155 KB File Size Full Detail 1,023 KB File Size Full Detail 28 MB File Size Low Detail 150 KB File Size

  28. Avoid unnecessary amounts of detail in components. Remove Not Needed Detail

  29. By using the “Derived Component” tool you can create single parts that represent a full sub assembly. Reduces File Footprint Reduces Memory Increases Speed Derived Component Tool Better Benefits Coming Soon!!

  30. Try to avoid using “shiny” colors at the part level of standard components. (Reduce Graphic Overhead) Shiny Setting of 50 or lower. Component Colors

  31. LOD in Drawing View Creation You can use the created LOD’s for creating drawing levels which will reduce the overhead and increase performance. Drawing View Performance

  32. You can control the hidden line display of individual components by right clicking on the component . Drawing View Performance

  33. Adding “Reference” assemblies can help with performance. Open smaller assemblies as needed for working Adds more capability with LOD’s Assembly Structure

  34. View Representations are another useful tool for manipulating and managing large assemblies. View representations allow a user to store preset configurations of component visibility settings and other settings enable and disable states. The Role of View Representations
