Nice ‘checklist’ style post over at RevitKing. Most things just come back to sensible modelling:
Revit.King’s BIM coordinator/ Revit Blog: Optimal performance for Revit!!!
One of the tips:
Create a family component instead of in-place families when possible, especially for repetitive components. Each in-place family has separate type attributes that Revit has to reference.
To implement this on an existing model, you could convert some of the in-place families to Component families using this method.
OK, the title may be a bit misleading. But this is how you can try to do it:
For Project RVT files:
- Export from higher version of Revit to IFC
- Import the IFC file into the lower version of Revit
Tip – use the best available IFC format that both versions of Revit understand
For Family RFA files:
- Load the family into a project in the higher version
- Follow the above steps for Project files
- Once you have the project in the lower version of Revit, open the downgraded family from the Project (select in Project Browser – Edit)
- Export to DWG or SAT from the higher version
- Import the file into the lower version
Tip – you probably can’t explode the resulting import, or everything will disappear.

Parveen has posted a pretty long list of BIM resources at the following link:
BIM Family files
If you want to find out the actual file size of families that are living in your project, follow these steps:
- In Revit 2012, export all families to RFA files (File – Save As – Library – Family – ).
In 2011, you might be interested in this method.
- View the exported folder in Windows Explorer.
- Sort By – Size
- You will see the most bloated families at the top.
Here is an example:
To reduce the size of the largest families, I can now:
- Open them from the project
- Delete any unnecessary data (such as imported DWGs)
- Purge and then
- Reload them into the project.
I anticipate significant size decreases for my (currently) 547 mb project!

While discussing an interesting baluster-with-lighting family, Steve reminds us that “Revit hates switching between shared and not shared status.”
You have to follow a strict process of deleting and / or renaming affected families that exist in the project if you wish to switch them from Shared to non-Shared, or vice-versa.

Do you have some awesome in-place families that you would like to convert to normal Component families, so that you can load them into other projects?
- Open the Project containing the In-Place family
- Edit the In-Place family
- Select all of the elements in the family
- Group all of these elements using the Create Group tool. Give the Group a name.
- Select the Group
- Do not Finish Editing the In-Place family yet!
- Go to the ‘R’ button (Application Menu) – Save As – Library – Group
- You will notice that the filetype is RFA!
- Save the Group somewhere.
- You Component Family IS the file that you just saved.
I’m sure there are limitation to this method, but I think it is very cool.
