10 Common Problems in Revit City and How to Fix Them

Revit City is a valuable resource for architects, engineers, and designers who rely on Revit families to enhance their BIM projects. However, users often face issues that can disrupt workflows and slow down design processes. In this guide, we’ll explore 10 common problems in Revit City and provide practical solutions to fix them.

1. Slow Performance and Lag

Problem: Revit files from Revit City can sometimes be large and cause lag.

Solution:

  • Purge unnecessary elements (Manage > Purge Unused).
  • Reduce the file size by removing excess geometry and materials.
  • Use Worksets to split models and improve performance.

2. Missing Textures and Materials

Problem: Some downloaded Revit families have missing textures or materials.

Solution:

  • Check if the textures are linked to an external path and update them.
  • Reapply materials using the Material Browser.
  • If necessary, replace missing textures with custom ones.

3. Compatibility Issues with Different Revit Versions

Problem: Some families do not open properly in older or newer versions of Revit.

Solution:

  • Try upgrading the family by opening it in a newer version and saving it.
  • If working with an older version, request a compatible format or recreate elements manually.

4. Overcomplicated Families

Problem: Some families contain unnecessary parameters and excessive details.

Solution:

  • Edit the family in the Family Editor and remove unnecessary elements.
  • Optimize the geometry to improve performance.
  • Use LOD (Level of Detail) settings appropriately.

5. Broken Constraints and Parametric Issues

Problem: Families downloaded from Revit City sometimes have broken constraints.

Solution:

  • Check Family Types for incorrect formulas or missing constraints.
  • Test different parameter values to identify errors.
  • If needed, rebuild constraints and reapply Lock Constraints.

6. Annotations Not Displaying Properly

Problem: Some downloaded families have annotation issues.

Solution:

  • Check Visibility Settings to ensure annotations appear at the correct scale.
  • Use Annotation Families correctly within model families.
  • Adjust View Range settings in the project.

7. Line Weights and Graphics Not Matching Project Standards

Problem: Imported families often have inconsistent line weights and graphics.

Solution:

  • Adjust Object Styles (Manage > Object Styles).
  • Use View Templates to standardize appearance.
  • Edit line weights in Family Editor before inserting into the project.

8. Parameter Conflicts with Existing Families

Problem: Revit City families may have conflicting parameters with your project.

Solution:

  • Rename parameters to avoid conflicts.
  • Use Shared Parameters for better control.
  • Consolidate duplicate parameters into a unified standard.

9. Scaling Issues with Imported Families

Problem: Some families appear too large or too small when placed in a project.

Solution:

  • Check Units in the family and ensure they match the project settings.
  • Use the Scale Tool carefully, but avoid extreme adjustments.
  • Adjust base dimensions within the Family Editor.

10. Difficulty in Editing Families from Revit City

Problem: Some families have complex nested components, making them hard to edit.

Solution:

  • Open the family in Family Editor and explore nested elements.
  • If necessary, create a simplified version of the family.
  • Save frequently while editing to prevent loss of progress.
