MEP Fabrication Parts Tabs and Priority with fill

[Tye Austin]

I am always needing to exclude fittings on the DWV copper tab in a waste service or vent service because if I use the Trim command to complete an offset or sometimes with the Multipoint Fill command, it wants to use the DWV fittings first.   Does anyone know how to prioritize the Palette tabs or fittings without needing to exclude tabs or buttons?  or maybe knows what Revit is using for prioritizing which fittings it is choosing when you do something like complete a 90 or 45 deg offset?

Its simply the order of the tabs and buttons.
First tab first button, second button, etc.
Put the tabs and buttons in the best order for your needs then use exclude for the oddities.

But that's our issue.  we have the No Hub tab first, at the top, but it wants to use the DWV parts first when doing some fill commands.  So it appears to be getting it's priority somewhere else.

Have you tried setting size conditions for the switch between material? We run our no-hub services with DWV copper set to 1-1/2" and under and have no issues.

If you are trying to run no-hub and copper at overlapping sizes in the same service/template, I'd suggest breaking out into two separate ones.

But then, if you break it out into it's own service, you have to fight service mismatch issues...   Seems like there should be a built in priority and setting the buttons or pallets up in that priority would sort out the trim / fill issues.

I just use the logic above without issue.

What happens if you try to place the components one by one manually? any errors thrown?

Also it you have an adaptor/connector ITM with one size to various sizes like 1"-3/4", 1"-1", 1"-11/4" always have the Size on Size first in the product list. Otherwise the fill does not fill for some reason and will skip to next tab. Its a bug it used to work regardless. A fitting like a press - threaded adaptor.

I have the tabs with the different materials all excluded from fill. When the detailer loads the model, they remove the exclude from fill material that they need.

Don't confuse this with excluding individual parts. We also use that on each tab to keep certain from filling (street elbows as example).

Would setting size conditions not work for you then? That will control the fill-in as well.

Service mismatch can be worked around by placing a part of a new service on the other service, accepting the error, then drawing off that part you placed. Don't try to multi-point route right off of one service with another or it will do that weird thing where it adds a bunch of other fittings.

You will always have a service mismatch, no matter how you slice it and dice it.  I have an underground service, and an above ground service, for the same ass parts...  still get a service mismatch when I switch.

If the DWV service is a pallet in my Waste service then I can put a DWV MIP into a cast iron tapped tee with no service mismatch.  Or a transition band.   once they are in different services that becomes a mismatch

That's good to know but my issue is specifically when doing multipoint fill or trim to complete an offset.  so it's usually just 45s and 90s that do not have reducing options.

Our database guy told me that he cannot exclude the tabs and that I have to do it on my end and it only lasts as long as you have the project open that day.  Can you give me any help on how you exclude tabs in the database?

It may be that we would just be asking for the size conditions on the DWV.  it is mostly 1 1/2" for us as well but sometimes we may want larger DWV for special conditions.  but...  they are special conditions so I can just struggle with that when it comes up instead...

No it only lasts for that session. It used hold in CADmep for Admin.

He can exclude tabs from fill by default in AutoCAD and have that transfer over to Revit, just like individual buttons. You don't do it in the template anymore. Just pick the service, go to the palette (don't go to any settings) and right click on the tab, click exclude tab from fill. You'll see a little [E] pop up at the end of the name of the tab. This will transfer over to Revit by default.
