MECHANICAL TEE

Does anyone guide me about how to use a mechanical tee?

What do you mean by a mechanical tee?

Mechanical tee is one of the fittings which is used to create a junction in pipes. when I try to load that family into routing preference it will get dimmed and I can't able to get the result in the model.

Hi @parathkrishna ,

Is it possible to share the family?

It will be easy to identify the problem.

Hi @Radish_G

Find the attached.

Although it says its a tee, its not as far as Revit is concerned.

Its a pipe accessory.

I think you have to insert it as a PA and work away from it rather than it automatically inserting at the junction.

You need a mechanical tee family?

Find the attached mechanical tee family in the trail conversation.

when I loaded into routing preference its shows in a hidden line and it will not appear while modeling the pipes.

Find my reply at part 6.

The family is a Pipe Accessory, not a Pipe Fitting and not a part type of Tee in Revit.

You could try changing the family category to pipe fitting and part type to tee and then it might work.

Hi @parathkrishna ,

Share the lookup table as well.

Name of the lookup table is "Victaulic-Grooved Coupling OGS-AGS"

Missing Lookup TableConnection

i tried it but i can't able to fix it.

I downloaded a fresh version from the Victaulic website https://www.victaulic.com/resource-software/

This version is a Pipe Fitting of part type Spud - Adjustable.

To use it in your routing preferences set the Preferred Junction Type to "Tap"

In use, it will attach to the pipe rather than breaking into it.

NOTE: it does not automatically adjust to the main pipe diameter, it defaults to 6" and you have to manually set the nominal diameter in the properties pallette.

Thankyou @iainsavage

it is working , but if i changed the Preferred Junction Type to "Tap" , the tee junction type will be disabled.

For every time i have to change the Preferred Junction Type . Is there any other solution for this?

Victaulic families are, I think, designed to work with their own Victaulic Tools for Revit plug-in, so I’ve tended to find that when used in native Revit they might need a bit of modification.

For what you are trying to do you would need to edit the family and I think it would be something like:

change the part type to Tee
add an extrusion along the main axis, to simulate a piece of pipe
align and lock the ends of the extrusion to two reference planes. They should be equally spaced either side of the centre left/right plane and the distance between them controlled by whichever parameter controls the overall length of the fitting.
the extrusion inside and outside diameter should be controlled by parameters matching the pipe inside and outside diameters in the pipe segments & sizes settings (you might need to modify and reload the lookup table and also maybe adjust formulas)
add Fitting connectors at each end of the extrusion and associate their radius with the nominal radius parameter
One of the original connectors can/should probably be removed (not the one which controls the branch size)
delete and purge the original family out of your project file
load the modified family.

It should now behave as a tee and adjust to the size of the main pipe (hopefully).

What version of Revit are you using?

@iainsavage

i am using 2018.3 version.

iainsavage — Wed, 16 Jun 2021 09:02:24 GMT

I can't help you with modifying the family then because you wouldn't be able to open my 2021 version.

You'll have to do it yourself using the steps above or maybe someone else with an older version can assist.

I will try to do by myself. If i need any assistance let you know.

The mechanical tee is technically a tap family.

(Revit Tees split pipes)

(Revit Taps attach to the side of pipes)

Pipe types know which category to use from the setting at Preferred Junction Type

Pipe types know which family to draw based off of the size table.

I Screencasted a video on how to draw them in native Revit.

https://knowledge.autodesk.com/community/screencast/f443822c-4016-4db9-80d7-287960e58ac1

Victaulic also has a tool in their add-in to draw lots of taps faster.

Hope this helps!

How? This family is supposed to split the pipe. How can it be a tap (technically)?
