Revit MEP Duct Rise/Drop Symbols
« on: April 03, 2013, 04:31:12 AM »
Is it possible to add a custom Rise/Drop symbol in Revit MEP?
The symbols available for ductwork don't comply with UK ductwork guidelines, and my boss isn't happy, but then he never is :-(

I need a way to replace the symbols, as it is he's ready to throw Revit MEP out as it doesn't comply with UK guidelines in so many departments

I have not used rise/drop symbols but, now that you mention it, I want to but I can't even find the ones you are referring to or how to get them in for that matter. I'm assuming they are a tag of some sort that looks at the slope of the duct. If you can get me going, I might be able to help.

They are located in the families section, in the Duct Systems bit.
open the systems, double click on the relevant system and the rise drop symbol is at the bottom.

Oh those rise/drop symbols. I thought you were talking about if there was a slope on a duct run. Really? None of the available ones work for you? Those are all pretty standard over here. I'll see if I can find anything about adding or altering them.

No you cannot change them at this point. You can use V/G to turn them off in the view, and create a Detail Family or use linework to simulate this.

As for your boss.... Revit is not a free form drafting tool. It is a BIM application for the engineer in the AEC industry. Revit's purpose is not to make things look the way AutoCAD does. Even then, the reason we have certain standards in AutoCAD is simply because they were grandfather'd in from hand drafting days. It was easier for a mechanical engineer/contractor to schematically draw single lines with symbolic representations for routing pipe/duct than to draw it as it would look in a realistic environment. Revit's purpose is the parametric capabilities and engineering information. If you want to "draw" then AutoCAD is still there, but you're losing in the long run.

Bottom line is this (for your boss): Accept Revit and move on.  :kewl:

Styk is right, they cannot be changed. I did find one blog entry from 2010(?) by a Revit dev that it is coming.

There is a UK graphical duct standard, and unfortunately none of the symbols match the standard requirements.  :-(

I find that a little hard to believe. Maybe it's because I'm in a different country, but it doesn't make sense that the entire United Kingdom will have a problem with a duct symbol on a plan. Standards in the USA change from job to job. Talking government only, each county, city, state or even federal job seem to have their own standard, lol. But the UK has plenty of awesome MEP Revit guru's and they seem to never have a problem. RevitForum.org has a ton of UK Revit masters.

I dunno.... *shrugs*

Its not the Entire UK, just my Boss, its by the book or not at all.
DW142 - DW144 are the standards I need to produce ductwork drawings to

From what I see, those standards are for the manufacturing of ductwork. I don't see any drawing standards related to that. Do you have any documentation for this standard? I can't find anything.

There is a graphical element at the back on how ductwork drawings and fittings should be laid out. Revit provides DW144 ductwork, just not the rise/drop symbols.
I've attached my uncontrolled copy of it here

So are you a mechanical HVAC fabrication shop, or are you a mechanical engineer? If you're a fabrication shop and are required to provide shop drawings, then Revit is not the program to use at this point in time since it's incapable of producing true shop drawings per the standards that you posted. If you're a mechanical engineering firm doing consultant work, that is not the correct set of standards to go by as you are not responsible for providing that level of detail - the mechanical contractor is if the job specs call for it.

This is my $0.02 anyways, from being in the industry for 12+ years now. :kewl:

If the rise/drop symbols were meant to be a part of the standard, then they would be called out somehow along with the different system types. They are not. I'd say that your boss is reading into that document way too much.

Sort of in the same vein as the original topic but..... where dahell did they put the symbol for rises/drops in 2012 and up?  There used to be a handful of options to choose from for the symbols, but I can't find it in the mechanical settings anymore.
