c3d 2024 and wyes

[jggerth]

I gotta say, it was exciting to read that Wye fittings would be work in C3D 2024 pressure pipe networks.  Of course, only one (1)! of the supplied catalogs actually contains any Wye fittings.  No PVC, No Mechanical Joint, No Flanged, No PushOn.  And seeing a TEE fitting placed with the branch pipe at 45 degrees is just .... how do I day idiotic politely?

Maybe the Developers would like to borrow  my copy of the American Standard Pipe manual?  or the Clough pipe manual?  Or a Spears PVC pipe catalog Maybe they could actually FINISH MAKING USEFUL CATALOGS!!

Maybe they could, but they are programmers and not, for the most part, civil engineers. It's how the mind was trained to think, to process what's important. Different training, different thought processes.

[jggerth]

Yes, but a huge part of the programmer's job, probably the single most important part, is working to understand end user needs and work with domain experts to ensure their product actually meets user needs and requirements.  The half-baked implementation of wyes in code, without updating the catalogs, is a classic failure of ignoring end users and domain experts.

Hyping a tool that doesn't work in the overwhelming number of situations is not the optimum way to keep or attract sales.

Oh, I forgot to mention that pressure pipe wyes are especially unimportant in real world civil design.  Tees and angles work, I've never missed having a wye.

[jggerth]

Your personal experience may not have missed having a wye, but that's just you. And yes, it usually possible to get around the lack by using a Tee and a Bend, but the real world cost of doing that are higher -- two fittings and a stub of pipe connecting them vs a single fitting.

It's just that out in the West there are not many cases where the streets don't meet a approximately a 90 degree angle. It has something to do with AASHTO.  Where are you finding a need for a Wye?

It's kind of odd to think that WYEs aren't used that much. How do you think sanitary force mains work? They don't use TEEs for the most part. I worked on the utilities for a $2.7B airport terminal project and had over a dozen WYEs that were required. Granted, I had to create my own catalog of hundreds of pressure fittings because Autodesk refuses to provide useful ones to the users. Another project I had for a deicing facility had dozens of WYEs for the various pipes of chemicals that had to be taken from the building to the pumps. 

The point is, OP is absolutely correct in that Autodesk doesn't truly think of the end users like it used to.

A sanitary force main? Never seen one of those that uses a wye. 2.7Billon spent and only a dozen wye's used, I'd call that infrequent use.  I barely use pressure pipes, let alone wyes.

Leaving product feedback goes in one ear and out the other.  Its sad really.  I want pipe sizes from 3/4" to sky's the limit.  If providing a AWWA catalog, then provide the criteria located in AWWA standards and manuals.  Its right there.  Pipe deflection, wall thickness, allowable pressures, etc.  All frustrating.
