New RMEP User, need assistance with pipes & new items

Hello everyone. My company recently purchased the Building Design Suite Premium so we have all 3 Revit's in a "box." I'm focusing mostly on the MEP side of things. Anywho, the background that I have is a 4-day training class for RMEP that was pretty much just the intro into the software and taught how to do layout, run piping and fittings, change some things here and there, set up sheets, etc. Now that I'm into the software back at the office, there are some things that I'm unsure of how to do.

 

First of all, when I took the class, they already had copper sweat fittings and pipe loaded into the software. I've got 2013 and though there is Copper Type L, M, K pipes in there, the fittings don't exist. They aren't availabe on Seek either, just the press-fit connections. I've downloaded the press-fits and managed to get them to work in here, but what's weird is the copper Type L pipe doesn't seem to match up to the size of the fittings, nor does it share the same copper color that the fittings have. If I do a 1" run, the pipe is bigger in diameter than that of the fittings, and it looks gray as if it were just the generic or steel pipe. I'm not sure where the look-up table exists for these pipes and how to make proper changes.

 

The second issue is I'm in need of making strut (uni-strut, 1-5/8" x 1-5/8") for building rack systems. Here is the link to a .pdf of the size we are using: http://www.powerstrut.com/ps200pdf/ps200.pdf . I'm clueless as to how to actually give this profile some intelligence and be able to draw it in lengths as if it were a piece of channel or angle like what the software comes with. I drew the profile in CAD and thought maybe importing the sketch would work best, but again, I never had schooling on this part.

 

If anyone has answers to these questions, links to other threads, or YouTube videos for any of this, it'd be appreciated. Thanks!

OTB lookup table location:

 

C:\ProgramData\Autodesk\RVT 2013\Lookup Tables

 

Revit ini location (look here to make sure the lookup table location is correct):

 

C:\Users\(username)\AppData\Roaming\Autodesk\Revit\Autodesk Revit 2013

 

This will most likely fix your pipe fitting size problem.

I know where the look up tables are located in the directory, but I'm there right now and don't see the Excel file for pipe. I see a bunch of Pipe Glued Vent Tee, Pipe Long Bend, Pipe this that and the other. No Pipe - Copper Type L or whatever it should be.

 

And what are you getting at with the Revit ini location? I went to that directory and there's 2 folders and some random files. Am I to direct to these file paths somewhere in the software? Thanks.

Open the Revit.ini text file, find the lookup table line and make sure its path matches where your lookup tables are located.  Typically when people have problems with pipe fittings not matching the pipe size, this is the issue.

Also, lookup tables have nothing to do with pipes.  They are what defines the dimensional data for pipe fittings.  Pipes are defined within Revit under Mechanical Settings.

Just looked. It matches up fine. Still doesn't help that I don't have any copper sweat fittings installed. Was hoping someone knew of a library thats available to use.

 

And I went into the Mechanical Settings and compared the dimensions on the tables of say, Type L Copper, with tables on a google search and they match up. I attached a screenshot of what I'm talking about though. Not only is the copper pipe not "copper" in color to match the fittings, it's over sized. These are 1" fittings and pipe. What gives?

You have a lot to learn.  (if I were you) I would expect the person that sold you the software to answer every one of your questions.  If you want to use anything other than what is in the box, somebody's going to have to do some programming.  The "standard" pipe-type uses the "generic" fittings.  They look like sweat fittings so I would start with that.

Are you referring to the attached picture? Those are actually the Nibco Press fittings available on Seek.

No, I'm not referring to the picture.  Before you downloaded any fittings, the standard pipe-type defaulted to generic fittings.  That may have been good enough for a start.  You have new fittings, but you don't have a new pipe-type with a matching profile (inside and outside diameter).  You were able to assign a "Copper" and "Type L" parameter to the pipe, but that didn't really do anything to the dimensions (let alone the coloer).

Ok, so I think I figured out (partly) what the problem is with the press fittings appearing smaller than the pipe sizes. It's not the pipe. It's the fittings that are the problem. The 1/2" press fittings are the only ones that appear to be sized properly for the 1/2" pipe, which appears to be inserted into the fitting. The problem is that any size above 1/2" shows a 1/2" fitting and then the correct size pipe. The fitting never changes it's size to match. The look-up table for the Nibco press 90 and all the dimensional data appears to increase with pipe size so why are these fittings not adjusting within Revit?
