Pressure Pipe Reducer Fitting

pjohnson — Tue, 20 Apr 2021 20:15:09 GMT

I am having trouble with adding a reducer fitting to my pressure pipe.

It adds the 8x6 Reducer with the 8" part of the fitting onto the 6" pipe and it is not allowing my to flip or rotate the fitting?

I've tried both adding the fitting in the middle of an existing pipe run and also splitting the pipe runs at the fitting and it will not allow me to rotate/flip the reducer either way?

Any help is appreciated. Thanks.

you can no longer flip, rotate or move reducers in 2021. You have to get them in the right order and in the right place. Draw pipes from large to small end (for me) because that is how it goes in. And since a network can only have one size of pipe you have to use swap parts afterwards to get the correct size of pipe in on the small end.

Thought I finally had pressure pipes figured out and now all of my fittings that were showing, have now disappeared.

Do you know why this is would be happening or how to fix it?

Thought I finally had pressure pipes figured out - good luck with that! Basically, you are finding that the software doesn't work correctly. Pressure networks are really sensitive to the slightest mis-step. When we have disappearing parts in plan or profile we have never found a suitable solution. You can dref the network into another dwg, or copy/paste it, and it doesn't matter - once corrupted the network stays corrupted. The only true resolution is to start over. It may have something to do with the parts list, or the connection to the parts list? What happens if you switch to a different parts list? We have created a tool palette with dummy parts in it so that we can get the dam plans out instead of wasting our time trying to find disappeared parts. The trick is getting it to label, so we have also created "placeholder" parts on Defpoints that you can label if you can get them to show. It's been a while since I helped someone figure that out, and it was for a disappeared profile view part, so I can't really describe the steps we took for the placeholder parts.

You will encounter problem after problem, all inexplicable, working with pressure networks. Be methodical and make no false moves, setting things up correctly from the very beginning or you'll keep running into mysteries like this.

I was afraid of that. Thanks for you help.

I'd be nice if they could figure out pressure networks.

If they worked like they are suppose to, it would be a very useful tool!!

I agree. I work at the water utility so we rely heavily on pressure networks. The benefits I see are in quantities, design of the vertical, drawing the parts in profile view and labeling. It's pretty darn frustrating, though. They was all the excitement about introducing pipe runs and using horz/vert alignments to control the layout of the network, which is a nice idea, but they not only didn't fix existing problems, but introduced new ones with pipe runs.

This is incredible. So they make the already half-baked pressure pipes even more broken with newer versions.

I don't care how much I'm repeating myself: pressure pipes are garbage.

Perfect, thanks.
