family edition : mechanical - part type

[philsogood]

hello

spending my time to try to understand how part type in pipe accessories work

there are several possibilities : normal/endcap/sensor/valve breaks into...

never exactly undersstant how to use it.... well i read this article but it's only dealing with pressure losses ans I know that part type has an effect on the family and how it works in the projecxt...

i bought several books dealing w=ith MEP, family but no book exist especially on MEP families (and there would ahev a lot of things to tell)

thanks for your enlightment!! 😉

Kind of an open-ended question, is there something specifically you needed more information for?

The article you've referenced explains two things - it explains what the accessory does to the pipe you click on (if anything), and it explains whether or not the accessory applies a pressure drop to the system.

That's about it. The accessory either attaches to the face of a pipe (think insertion probes or hot tapped pipes), the end of a pipe, or splits the pipe (valves). Choose the one that best matches your real-world condition.

@fabiosato 

for endcap and sensor, why the connector should be oriented to the left?

on others families why the first connector shloud be on the left?

Hello,

I follow this setting since I started using Revit 2014.

This orientation, at that point was the only one that worked.

I'm not sure there's ever been user documentation that cleanly explains the various connector orientations for different equipment categories/part types, but generally speaking the orientation of an equivalent out-of-the-box Revit library family (like Generic Elbows for duct elbows even if you want one made out of phenolic duct or fabric duct) is the only orientation that will allow the family to function with point-and-click placement onto other MEP network items, Connect Into command usage, or Routing Preferences.

It might have been something as simple as 'the early Revit programmers picked a direction and that's what we work with now'.
