• Set the subcategory of ALL geometry in nested and host families.
  • Don’t create too many overly complicated subcategories. Keep it simple. Avoid naming that is too specific that forces you to create another subcategory for something that is essentially the same thing. For E.g. “Access Hatch” and a separate category called “Air returns”. Perhaps a subcategory that can be used for both is better suited. E.g. “Mechanical Rep”.
  • Make sure when using line styles that you choose the correct subcategories from the Type pull down menu. E.g. Windows [Cut] vs. Windows [Projection].
  • Make sure not to make spelling mistakes when using Family Subcategories across a range of families because it will import each variation separately into your Project file or Template. Consider creating an Excel spreadsheet of all approved subcategories and copy and paste text to ensure the name is identical in all families across your library.

Here is an example of what happens when several families are imported into a Project file using similar – but not identical Family Subcategories. This makes editing and creating View Templates a nightmare because it becomes very time consuming to work out which Subcategories belong to which families.
