ok, sorted. can be close now

Or maybe preferred jonction type on Tee ?

Yep, exactly. BTW, had to create another pipe segments with tap as prefered and switch between them to use either tap or tee branching.

You dont actually need to make separate duct/pipe types if you want to use both taps and tees. For example I like to use taps to connect round duct to rectangular but Ts for round to round, but just have 1 type of round duct.

Make one type, with Tap as preferred junction type. Then add a T (Just as you have done here with it greyed out)
To make a tap, just trim onto the pipe or drag the end onto the pipe/duct.
To make a T use the corner trim instead, so it makes an elbow. Click on the plus so it makes the elbow into a T (The one in routing preferences will be used) and continue drawing..

The Pipe Type should be one thing only.. The specified type of pipe that it is. With type properties for material, fittings etc. 'With Ts' or 'With Taps' are not a specified type of pipe or duct and will just make it more complicated if you need to make Bill of Quantities etc.

Also its better to be able to select a whole run of pipe and do 'change type' or 'reapply type'. If you have 1 type with both taps and Ts defined, it will change the pipe type, and even replace Ts with different Ts and Taps with different taps, without messing up all the connections.

Nice one body, thanks a lot
