I’ve seen it in mfr’s created families (Greenheck utility fan is a good example). It looks like a complicated string of formulas referring to several parameters. I don’t know enough about the formula language to deconstruct it. I’d like to know how to do it too so if anyone can break it down it would be appreciated. (This is the reason there’s businesses specifically devoted to creating families)
The only way I have achieved this is to use Reference lines in an array and attach connectors to the workplane at the end of the reference lines. You can then use a parameter for the number of items in the array which means the connector is removed along with the reference line when the array gets smaller. This will only help for very simple plenum families where the connectors can be arrayed though.
An example attached below
Anyone know if a way to do this has been introduced in MEP 2011? I'm trying to do exactly the same thing but have found no way of doing it. It seems like it would be a useful feature to include.
