In
Revit, the following auto fill tools can be used to quickly and automatically place MEP fabrication parts in a model:
Some of the factors that influence how MEP fabrication parts are chosen when using these auto fill tools are described below. Note that the behavior is slightly different, depending on the tool.
- Exclusions: Parts that are indicated as excluded in the MEP Fabrication Parts palette are never used for auto filling features. For example, if you have three different types of elbows displaying in the MEP Fabrication Parts palette, you should exclude the ones that you do not want, so that the preferred one is automatically placed, when using auto fill tools. For more information, see
Exclude Parts from Auto Fill Tools.
- Fewest number of parts:
Revit chooses the solution (part) that requires using the fewest number of parts in the run. For example, when adding to an existing run, a tap will be added, instead of a tee.
- Most compact solution: When multiple solutions with the same number of parts exist, the most compact solution is used.
