Model elements are derived from the following sources:
- Manufacturer’s Model Elements Elements created by and acquired from manufacturers often have more information than is prudent to keep in the BIM model; the appropriate level of detail should be retained for the design element. However, embedded performance data remains for analysis and specification purposes. Custom Created Model Elements Custom model elements that are created use appropriate BIM
- Authoring tool templates to create custom elements. Custom models components need to be assigned as a part and part of a family or group.
