6- Follow this Hierarchy of Good Families
This priority order should be followed when you are trying to find families for your project:
1- Internally developed families
Your team is always the best choice for families. Because they will meet your firm standards, it is easy to build exactly what you need.
2- Families formed by trusted external collaborators
If you lack the qualified staff to build families or if you don’t have enough time, trusted collaborators such as BIM consultants is the next best option. Families shared by architecture/engineering firms you are collaborating with can also be a good option.
Autodesk has created three default families
If you can’t build your own families or don’t have trusted collaborators to build them, the next best option is to look at what Autodesk has available in their default libraries. These families may not meet your standards but they can be a good starting place.
4- Downloaded manufacturers’ families from websites such as “BIM Objects” and others.
We are now in the danger zone. The vast majority are low-quality. They can be over-modeled, have too many parameters, and are very heavy, which will slow down your model. If you have to use them, be sure to check and clean them before.
5- Downloaded families from Revit community websites such as “Revit City”.
Families who are found on community sites are almost always bad. Avoid them.
Depending on the size and scope of your company, you may decide what content users can purchase. A large company might ask users to keep to the families they have created internally. Smaller firms might allow loading some default Autodesk libraries.
It will take some time to find the best solution for you. You need to find a balance between keeping quality control, but also giving some freedom to users, especially if they don’t have quick access to internal content creators.
