Duplicating a Family without the parameters

[saifulshahrial.binmohdnoor]

Hi All,

I currently have multiple families in the project that has alot of parameters within them.

These families ends up making my project file huge which creates performance issues (such as long loading time).

Is there a way for me to make a copy of these families where they are just basically a "shell" without any parameters in it? It's ok if I'm not able to make changes to the families since I won't be making any more changes to the family. I just want to reduce the size of my file in general.

Thanks for any help!

I strongly doubt that the parameters are the cause of the issue. Parameters, text and numbers take up only small piece of memory. (Many/Complex) Formulas can have some impact if those are used to modify the geometry of the family. Only then when you have many relationships. Even than its biggest performance is when placing the family from the family browser.

So usuallly it has more to do with other factors.

HERE a page with more infomation about Revit performance. Also check the linked PDF on that page (2017 Model Performance Technical Note.). It goes into detail about factors causing performance issues. Even when older it still applies in general.

There is no easy way to strip parameters from families. Depending on the amount of families, you could write a Dynamo script that would load the family and delete the parameters and then load it back into the project. It still might cause lots of issues if you are not careful causing families not to work or show as expected. I would not go this route.

Its more likely to be the geometry which is causing the problem. 3D geometry = lots of maths.

As a first step though have you tried using the Purge Unused tool on the Manage tab to get rid of any families etc that you aren't needing? Also try doing a Save As>Options>Compact File.
