Default Conduit Settings

[Anonymous]

How do the default Conduit Settings, specifically sizes such as ID, OD and Minimum bend radius come into play with Revit?

The Revit Conduit and Elbow families seem to be based on separate criteria, namely imported CSV lookup tables... so do these values have any bearing on the 3D modeling... or is it just impact calculations?

So I take back half of what I said. 

The conduit is based on the Electrical settings.  The Elbow is based on the lookup table. 

Still trying to wrap my head around if they are related to each other though.

Parameters in the Fittings family are set to refer to the Lookup table that is embedded in the family. the lookup table can be exported and edited in excel and then imported with new values if needed. the fitting size is selected based on the conduits Nominal Diameter and the fittings families specified in the Values parameter of the Conduit Types > Fittings category.

Yea... I do see that.  From what I gather the Conduit and elbows are both unique, just share a common "trade" size.  The Trade size is used to pull from the Electrical Settings Table for conduit, and uses the Lookup tables in the families imported lookup table  for elbows.

With that said... one setting I have not been able to find is the difference between a "with fittings", and "without fittings" elbow.  What actually separates the two?  I believe I understand their function (one presumes continuous / field bent conduit for material accounting purposes while the other presumes manufactured elbows are used for material accounting purposes) but is there an actual difference in the families that separates them? 

Or can I use the same elbow family for both types and the accounting is resolved by the system conduit family type?  ("Conduit With Fittings" or "Conduit without fittings.")

we don't use a lot of conduit in my office, but my understanding of the with/without fittings is the specified "fittings" are still used, it just doesn't show the joins. somone can correct me if I'm off on that :-).

Need to be careful on fittings vs "fittings".

Sloppy on Revits part, but you have fittings as a family and fittings as a physical component.

In both cases ("without fittings" and "with fittings") Revit Family "fittings" are used for elbows, transitions, etc.  However the distinction lays in how Revit calculates the lengths of conduit. In one system, Revit treats them like its a continuous length of pipe that is field bent as needed. 

In the other, Revit treats them as individual entities for material take off purposes.

I like to fully understand a family before I say its "completed" though, and this distinction on how they are created doesn't seem to be documented anywhere.  However OTB Revit families have elbow families that specifically indicate "without fittings" so that worries me that I am missing an important selection / checkbox somewhere.

There are a lot of good classes on AU-Online to watch too. not all may pertain, but good classes nonetheless.

Have you tried to find some tutorial videos on youtube?  May clear things up a bit... it did for me.

@s.borello and @hmunsell 

I've tried looking online for tutorials and videos but I cannot seem to find anything specifically about the generation / manipulation of System Families (Conduits) and how the elbows and fittings relate to them other then it being a selection in the family type to default to a certain one.

Like I said, what concerns me is AutoDesk themselves made an elbow without fittings along with an elbow with fittings (no graphical difference) so despite having no evidence it matters, I am led to believe that it does matter to someone at AutoDesk...

See link below... the author has several books that I found quite useful.

Hey!

Thank you for the article!

I am modeling electric models in an electric engineer office, and I am trying to improve and develop electric modeling in the office.

Do you know if revit does/prepares automatically the panelboard schemes?

With the circuit numbers and places where they are located?

If revit does that, what do I have to set in the parameters?

thank you very much!

Hello,

You can create the panel schedule by selecting it and using the create panel schedule command.

You can customize its appearence in the Manage Panel Template window.

FabioSato,

and this command creates the 2D scheme too?

[fabiosato]

Hello,

Revit does not cover 2D schemes, but some plug-ins can make them.

[valerya]

Thank you, do you know which plug-ins?

[fabiosato]

Hello,

I believe Desing Master Electric can make it. But check before buying it.
