1. Always keep family file size in mind. Get best solution with minimal file size. Avoid excessive use of voids and nesting where possible.
  1. Make sure that ALL unused nested and host families are purged in the Family Editor (This is an instance where I do recommend in purging) BEFORE loading into host family or Project file for testing.
  1. Lock geometry into Reference planes rather than into other geometry. See section on Reference Planes.
  1. Have a clearly defined, consistent Parameter naming convention. (Avoid abbreviations.) Ensure that these families are methodically made and linked with consistency in mind
  1. Model up the right level of detail for the desired outcome you wish to have.
  1. Think about the output and how the component may need to change or the various options users may need BEFORE you make the family. Add the correct restrictions; use Instance and Type parameters appropriately.
  1. Choose your type names well and with forethought. (See Type name section)
  1. Avoid Copying and pasting families across Project files
  1. Have a designated, experienced and well trained Content Creator/ Content Manager in your office or use professional Content creators. The “First in … all can have a go” approach is far from ideal.
  1. Set Origin point right the first time. Avoid changing Origin points of a family once it is in use in Projects. Changing Origins points after a family is in use negatively affects drafter confidence. If drafters experience families moving when re-loading they will be reluctant to reload any repaired families.
  1. Have good Subcategory naming conventions that can control family geometry through View Template. Subcategories are case specific. Be exact in your naming.
  1. Choose the appropriate Family Category. See Cuttable and Non-cuttable families in Help Menu. The category you choose will determine whether the item, when cut, will display as an elevation or section profile.
  1. Use Instance parameters if you want documenters to be able to adjust the family without creating new types.
  1. Use Type parameters if you want to control type information and force drafters to create a new type if a critical type value needs to change.
  1. Use formula ghosting of Parameters to protect important Parameter values or the relationships between parameters.
