    Question What Parameters Should I Make Shared?

    I work for a ventilation company and I have been making families for a couple of years now and have only now got around to learning how to make shared parameters i.e. 'scheduleable' info. I make families for fans, AHUs and HRUs.

    What I would like to know is what parameters I should be making shared? Is anyone able to give me a list of the things that typically get scheduled for this type of equipment. I have many parameters set up in my models i.e. electrical loadings/data, dimensions, weight, part codes, company info, heating/cooling coil information, fan speeds/powers, quote reference/location etc. etc.

    What needs to be scheduled by the people using the families exactly? I've not really got much experience on the project building side of things so any help would be brilliant.

    This is kind of a torn subject. Most MEP guys already have their own schedules in place, so when they download manufacturer's equipment, they strip the SP's and remap them with their own so their own schedules show the exact hand-picked info they want. Plus, most people have their own naming standards on SP's.

    So while it'll be productive for the end user of your company's Families who don't have these standards in place, it'll be a moot point for the others.

    But to answer your question disregarding what I've said above, basically, all of the performance data properly mapped to the correct parameter type is best. And most definitely the electrical information.In other words, don't just use general Parameter Types such as "Text" just to have a spot to fill in manually. Apply the real-world engineering unit of measurement behind it.

    As for the electrical information, always apply the proper electrical connectors, and map every one to a shared electrical parameter. Keep Voltage and Number of Poles as a Type Based, and all your Apparent Load and the rest as Instance Based. If there's additional electrical connections that an electrical engineer will have to connect the load back to a panel, then put it in (Heater Coil, low-voltage control box, etc). This is very important because the electrical guys can Copy/Monitor the HVAC equipment and connect the loads to circuits and panels immediately. Design Airflows should be set to Type Based, but Actual should be applied to the Duct Connector and set to Instance Based if you want your Family to process calculations. And so forth. It gets really in depth actually.

    Also, dimensional information is good too. Overall LxWxH, and any duct, opening or pipe sizes. Even filter sizes would be nice to have shared. This way BOM's are created easily in a tabulated data format.

    I've uploaded a couple of very rough 'n quick Families I built for a current job in an attached example project. It's actually not worthy of me uploading as they're so... bleh. They were very quick Families just to throw something in, and I half-assed the SP's, but it's enough to show you how I name my SP's, how I apply them to connectors, and how I format my schedules. The file has two units, and one sheet that shows the schedules. Again, I wish I had a better example to show off but I'm sure it'll get some creative brain juices flowing for you. Hope this helps!

    I'm sure I replied to this earlier. I definitely typed it all out. Ah well.

    Thanks for the great reply. Unfortunately the most recent version of Revit I have access to is 2015 so I cannot open the file you uploaded but this written info is of great help.

    Thanks a lot.

    I'll upload a 2015 version later today when I free up some time.

    mrgrotey, as promised, below is a link to another job that is Revit 2015. I purged everything in the project, but left duct and equipment layout and overall HVAC sheets. If you refer to the HVAC schedules sheet you'll find what you want. Double clicking the schedule will bring up the editable schedule. Reference the parameters in each Family to get ideas. Again, very basic stuff here so my apologies in advance for not having a better example!
