flanges pipes without flange fittings and only flange accessoiries

[Anonymous]

When i am drawing a pipe with flanges also all bends and all other fittings are drawn with flanges.

Is it possible that only the accessoiries e.g. valves en pumps will drawn with flanges and not the fittings.

Regards.

The only way I know is to set up your pipe type's routing preferences with generic fittings (no flanged fittings) everywhere, and load the flange you want but leave the routing Flange set to None. Then draw your pipe without flanges and just manually insert a flange when you want to.

Hi Chris,

first i tried with combining the with and without flange pipes but that doesn't work.

than I tried your way but sometimes the flange disapears when I for example afterwards change the pipe lenght or size.

Do you use flange as a fitting or accessoire ? 

second is that i can't make a correct system because the flanges are not joining together. How did you solf that problem ?

I make the whole system without flanges. Then, one place at a time, I pull a pipe end back leaving a gap (this separates everything into two systems) place flanges on the end(s), grab the face of the flange by its connector symbol, and drag it back into place on an accessory or another flange (they connect and everything becomes one system again.

Flanges disappear when you change a pipe in any way that causes a recalculation in Revit, because Revit checks the routing setup again and sees that the pipe type isn't supposed to have flanges. It's easiest for me just to add them back in on the occasions this happens, but I've seen two work-arounds as follows:

1. Call your pipe type something like "SCH40-BLK-WLD". Duplicate it and call the new one "SCH40-BLK-FLNG". Set the routing preferences for this new type to have flanges. Change the pipe in your project to the FLNG type only where you've got flanges, and then they shouldn't disappear anymore.

2. Split the pipe right near flanges. This should (if you've set up routing preferences correctly, add a union(coupling) at the split. Now you can make changes to the pipe on the other side of the union and the recalculation only goes as far as the union, so it doesn't get all the way to the flange and delete it.

I've tried both of those, and they've both still got wonky behavior. So like I said, it's just easier for me to put flanges back in occassionally. Anyway here's a pic proving my flanges all connect. Just have to drag their connectors to the mating connector correctly.

Thanks for your input to solve my problem.

you helped me a lot.

I'm experimenting with another work-around... Try this:

Select one of your flanges. Click the Edit Family tool. Open the Family Category parameters and change it from a pipe fitting to a pipe accessory. Load it back into your project.

Of couse when you want to insert one you click the Pipe Accessory tool instead of the Pipe Fitting tool. But otherwise, I'm not seeing any behavior difference except that they no longer get recalculated out of the run when you resize or something. Do you find any negative side effects of this work-around? Well, I suppose if you're going to schedule either fittings or accessories, it's going to show up in the wrong place, but any other side effects?

That's funny, I was just trying this and it works great !!

I haven't tried it yet, but I'm guessing a flange that's categorized as an accessory isn't going to place automatically if you ever DO want to set routing preferences up with a flange and insert them automatically everywhere. So maybe instead of loading the modified flange back into the project directly, save it with a new name in the Accessories folder, then in your project Load Family again to bring it in.

In this way you can maintain the normal usage of flanges as fittings if you want too, but still have your accessory flange to insert manually.

It work fine, but the flanges take not the right diameter automatically if i use as accessories, i need to select the right dimension after i connected.

It's right?
