How to manage Revit and improve, optimize, or troubleshoot model performance.

Solution:

Overview

Here are some initial items to look at when looking to improve Revit model performance:

  • Purge Unused Objects Remove unused views, families, and other objects from the project to improve performance and reduce file size

  • Project Views and Performance Minimize the number of views in a project to reduce model size. Likewise, consider deleting as many views as possible from static models linked into the model.

  • Plan Efficient Rooms and Spaces Promptly resolve warnings about overlapping room boundaries.

  • Review and Remove Plan Regions: Check for plan regions, as they can cause performance issues. Delete unnecessary plan regions or remove the sketch geometry, especially if they appear in review warnings.

  • Simplify Complex Area/Room/Space Boundary Lines: Review and simplify complex area, room, and space boundary lines to improve performance.

  • Worksharing Performance: To reduce disk usage, regularly compact central and local files

  • Worksets and Performance: Put links and imports into individual worksets and close the worksets when not in use.

  • Create Multiple Types within Families: Instead of placing multiple independent generic models in the Revit project, consider creating multiple types within the family.

  • Model Efficiently Reduce Complexity or Adjust Visibility: Either reduce the complexity of the extensively detailed elements or make sure that their visibility is limited to "fine" detail views only.

Cloud workflows

  • Asynchronous sync: Use the Activity Indicator, or work out another workflow so that users do not synchronize at the same time.

  • Hard drive space: For available storage, plan on three times the total Revit model sizes accessed by a team member for their workstation.

  • Bandwidth: The minimum recommended bandwidth is symmetrical 5 Mbps, while its maximum throughput is 50 Mbps.

  • Revit Links: It is recommended to upload Revit models to cloud project through Revit, and to link through External Resource (instead of Desktop Connector).

  • Links: Avoid links that do not cache data on the local system (like Revit cloud models and the Desktop Connector do).

  • Personal Accelerator (Pac): If working with large models with many links, update Pac to v24.4.14.0 or later to allow caching of more links (200) and more total cache size (10GBs).

  • Post Upgrade Performance Problems: Publish each Revit model after upgrading a project, to improve performance due to temporary link upgrades (this would affect Shared/Consumed linking and Desktop Connector based Revit links).
