You can refer to the following documents for Revit Best Practices:

Highlighted below are some best practices recommended to reduce Revit file size:

  • Minimize the use of Revit in-place families
  • Maintain fewer and only essential links
  • Link only in appropriate view. For example, a detail should be referenced to a detail view
  • Use graphical symbols whenever detailed modeling is not required, such as for plumbing fixtures, furniture, etc
  • Avoid use of extensive details (on railings, extensive fences, separation systems, etc.) unless necessary. Determine appropriate level of data granularity
  • Minimize the use of void forms when modeling
  • When modeling, use families rather than groups
  • Avoid exploding geometry unless necessary
  • Delete unused groups
  • Purge model files on a regular basis
  • Create and use a default view with minimum information
  • Set model view depth to a minimum
  • Eliminate unnecessary views from model files
  • When possible, use wireframe or shading view option instead of hid-den or shading with edges view
  • Turn off shadow when not necessary for viewing
  • Avoid using volumes unless necessary
