  12. 12. Manufacturer web sites
  13. 13. Outsourcing
  14. 14. Have someone developed in-house</li></li></ul><li>What are Families?<br />3 Major Types of Families in Revit:<br />System Families<br />Component Families<br />In-place Families<br />
  15. 15. Pros & Cons<br />Free downloaded Families<br />Customized Families<br />
  16. 16. Pros & Cons<br />Pros:<br />Yes, they are free! So it means they are ready to use!?<br />If from Manufacturer, it gets all the data you need for your model (schedule, analysis…)<br />Pros:<br />Can be made into anything (Almost everything)<br />The creator has total control on the family.<br />Can suit the need for the office.<br />Can be parametric, have more than 1 type.<br />Can be more consistent<br />
  17. 17. Pros & Cons<br />CONS:<br />Heavy on files size.<br />Limitations (e.g. breakable, non-parametric, hosted) <br />Too detailed!<br />Created by imported geometry (e.g. dwg file)<br />Needed families not existed.<br />Cons:<br />Time consuming to build, quality assured.<br />Can be problematic if creator is inexperienced.<br />No budget to afford it in-house.<br />
  18. 18. Examples<br />Sources:<br />Revit City<br />Autodesk Seek<br />Sweets network<br />Various Manufacturer Sites<br />
  19. 19. But what if no content is existed?<br />Solutions?<br />“Find one that “close” enough and tweak it!”<br />“I have a 3D dwg file and import it into the model.”<br />“Just trace over the cad drawing with model lines and group them.”<br />Answer: Maybe?<br />
  20. 20. GOOD Solutions<br />Why not start from “SCRATCH”?<br />
  21. 21. 4 Simple Rules* when Building Your Own Families<br />Beneficial: Not just to you - but to the project team<br />Efficient: Implementation and changes are fast and predictable<br />Elegant: Understood by the team and any last minutes new members<br />Repetitive: Can be used on many projects<br />*(Quoted from Phil Read)<br />
