There are normally several key families that need coordination via Copy/Monitor from discipline to discipline in a Revit project. This post will focus on plumbing fixtures like toilets. The architect is responsible for the overall layout of the bathrooms. Namely they need to design within accessible design standards. The engineer isn't as worried about placement as they are worried about the sizes of pipe connections, pressures, slopes, and so on. The tool to help the engineer navigate this situation is Copy/Monitor with Type Mapping. This allows the engineer to use their own fixture family with a full complement of connectors and rich parameter data while monitoring the placement of the toilet which is being driven by the architect. The engineer can set the tool up to provide an alert if the toilet is moved by the architect.
If Copy/Monitor is being used for plumbing fixtures for instance, be sure the origin lands at the same place family to family. MEP designers generally like to set the origin of their families in the corner so that the mouse pointer is directly over the corner of the object while deciding on placement. Typically, architects like the origin of an object to be directly in the middle. This is for practical purposes as well. If there are several different sizes, the family will grow or shrink from a central point. The differences aside, if the origins are different, the Copy/Monitor will appear to not have worked and cause confusion.
The way to discover the origin of a family is as follows. Select an instance of the family (either one) and click “Edit Family”. Within the family, there are normally at least two Reference Planes. In the properties, at the bottom, there is a check box for “Defines Origin”. There can only be one Reference Plane in each major direction to be able to define the origin.
Check each Reference Plane:
Defines Origin is checked here,
Defines Origin is checked here also,
Means that the Family’s origin should be right in the middle on the fixture side of the wall. Now visit the other fixture to check the Reference Planes and which define the origin. Once they are matched up, the families should land right in place when they are Copy/Monitored.
It will also cause fewer problems for the Copy/Monitor process if both families can have the same kind of hosting. Face based hosting is the most versatile in my opinion.
