    Turning off or hiding unused connectors

    The HVAC company I work for create configurable Revit content from a product selection software. The families used have a number of duct and plumbing connections in them but they are not always used for every product. Is there a way to turn off or hide the unused connectors when generating the external type catalog?

    Thanks for any suggestions,

    Not practically...that written...

    A connector that is part of an array will disappear when the array count eliminates an instance. For example an array of four solids with connectors will turn off two of them if the array is reduced to just two.

    A nested (Shared) family with a connector can be turned off/on and the connector won't be visible...but then it won't be visible EVER, either way, which makes it nigh impossible for users to know it is there.

    Other than those two techniques...I don't recall hearing about any others... As such I generally fall back to unique families, that vary only because of the number of connectors, as the solution that is easier for users to contend with.

    No, sadly you cant turn them on and off...

    The method I use is to place the connectors on a small extrusion that can be moved around with position and rotation parameters. Then for a type with less connectors you just put the unneeded ones in exactly the same place as the ones that are used, so the user only sees one.
    Then when a user tries to connect something, they get a menu asking which connector they want, which I actually find really useful.
    This lets you make many different things as Types instead of separate families.

    Suppose you have a generic 'Mechanical' family with 4 connectors (2x return and 2x supply) and you make a pump that has only 2. You can place one return and one supply on the 'out' part of the pump and the other return and supply on the 'in' part. Then you dont need a different family/type to place this pump in a hydronic return system or a hydronic supply system. Just choose which connector you want.

    I've been doing this as well, but I recently noticed that Revit was using the wrong connector, even though I selected the one I wanted from that menu. (This was in 2016, for what that's worth.) My solution was to place the second connector on a slightly different position in the axis of the connectors.

    But really, what's the problem with having extraneous connectors floating around? They don't print, and aren't visible unless the user selects the family. I just turn off the geometry that they're attached to and leave it at that.

    Or set the position of unused connectors to be in the middle of a family at the origin. Should be quite obvious that they are not on an actual connector location.

    Doesn't an unconnected connector generate its own system? And doesn't that in turn slow down performance? Or is my info out of date?

    No not automatically, only if you connect something, or you can choose to create a system for an unused connector.

    Technically any connector that isn't assigned to a specific system gets added to the Unassigned system. Autodesk says too many of those can contribute to poorer performance, for whatever that's worth.
