Conduit Size Settings not applied to conduit segment correctly

[Anonymous]

Conduit segment is not taking the correct 'Outside Diameter' param value. This leads to a really annoying visual inconsistency (see screenshot).

Seems like maybe the incorrect value was hard-coded into the Conduit Segment system family, instead of correctly referencing the Conduit Size settings.

Please advise.

Most likely your conduit is fine, but the fitting does not match your conduit settings.

Fitting dimensions are hard coded into the the family using lookup tables.  In the attached screen shot the column FOD##length##inches gives the outside diameter in fractional inches.

I second what Tim said. I'm 99% sure that's where your issue is.

Thanks for the try, but I'm 100% sure that's not the issue, because I created a lookup table from scratch specifically to match the OD in my Conduit Settings.

Look at the screenshot from my original post- THE CONDUIT SIZE SETTING IS NOT BEING APPLIED TO THE CONDUIT SEGMENT SYSTEM FAMLIY !!  That problem has nothing to do with any Conduit Fittings.  I just showed the Conduit Fitting next to the Conduit Segment to highlight the issue.

The lookup table from my conduit bend famlily, next to the conduit settings dialog (feel free to check the decimals):

Have you double checked your EMT Conduit Type? It shoud be associated with the Standard you've defined in your Electrical Settings.

If having the setting for EMT conduit not loaded into the conduit you are using is not the issue, the other mistake I have made is not reloading the lookup table after updating it.

If all of this is correct there may be something in the family we are not seeing, or it could just be a display error.  Try PDF'ing the view and see how it looks when printed if  this is even an issue worth pursuing.

Now we're on the same page.  And yes, I did check that:

No, you're not following me yet..

This has nothing to to with Conduit Fittings, Lookup Tables, graphic errors, display settings or anything else.

This is a problem with a System Family, which cannot be resolved by any user.  This is an Autodesk problem.

LOOK AT THE SCREENSHOT FROM MY ORIGINAL POST.

LOOK AT THE OD PARAMETER IN THE CONDUIT SETTINGS DIALOG.

LOOK AT THE Outside Diameter PARAMETER IN THE CONDUIT SEGMENT INSTANCE PROPERTIES.

THEY DO NOT MATCH.

THEY SHOULD MATCH.

Oh I followed you, and I've also been working with Revit long enough to realize some things just display odd at times, IE a display error.  You have provide screen shots but that only tells part of the picture.

Do NOT get upset when someone is providing you various possibilities just because you have gone through some stuff and not told anyone. It is extremely rude.

No one here is getting upset or being rude.  I've used italic, bold, and ALL CAP text to emphasize some points, because communicating through text on a screen is difficult.  You don't need to take offense at emphasis.

As for 'gone through some stuff and not told anyone' / 'provide screen shots but that only tells part of the picture', the first screenshot I posted showed (highlighted!) 2 numbers that should match, but didn't -- that cannot possibly be caused by a display error.  That IS the whole picture, and I DID tell you about it (hence the current discussion).  There was enough information there for @smbrennan to figure it out (without taking offense, I might add).

Take a breather dude.

This is actually a rounding thing that Revit did.  Conduit sizes are rounded to the nearest 1/32". The original size was entered in as 2 25/128" which is where that number is coming from.   You can either modify your family to be the exact measurements of the conduit, or you can modify the EMT sizes of the conduit to the rounded values.  

If you modify the electrical setting for conduit sizes you will have to change them to something different than what is displayed, hit ok,, then change it back to the rounded numbers.

@timlove  Good info.

So to confirm:

The discrepancy is between the rounding applied to the display of the OD value in the Properties panel vs the rounding applied to the display of the OD value in the Conduit Settings dialog (in other words, the display of the OD value in the Conduit Settings dialog is rounded to the nearest 1/32" (= 2 3/16"), even though the true value of the field is 2 25/128") ?

Is that right?

That sounds correct.  With how Revit works if you just type in the same value it displays it does not correct it from the true value to the new value.  It needs to be a big enough change (at least the rounded value) for it to take affect.

Where I work we didn't concern enough with the small variance when making objects since when they are in PDF form with line weights it is not noticeable most times. We also usually print with conduit and conduit fitting at Low Detail Level so there is only one thick line for the conduit and just tag it for sizes.

If you ever dig into the database and look at the absolute values that Revit uses they are crazy.  Very little is actually at a normal number any of us would use.

Gotcha.  Thanks for the legwork.

You're right that it doesn't make a difference when printed out, but as I work I am constantly doing little visual checks to make sure the model is doing what I expect.  One of these is looking for solid lines that should be broken, or broken lines that should be solid.  This conduit size discrepancy tripped that red flag, so I had to stop and dig.

Thanks again.
