Family Reload From

[lumoric]

How to programmatically assign a new path to a family? 

family.LookUpParameter("File Path") returns the path but the parameter is read only.

I have an almost identical family I'd like to replace in document but don't know how. I've tried temporary storing Parameters from old family and assigning them no a new one upon LoadFamily(), but it also doesn't work.

When I do it manually, right click on family tree > reload and repath, it works perfectly. All old parameters stay the same value.

Thanks,

Luka

Try using the overloaded. Ersionnof the LoadFamily() method that allows you to specify options like overwrite Parameters.
