Difference between Round Duct Transition ...

What is the difference between
Round Duct Beveled Cross Slip Joint US Imperial
versus
Round Duct "Transition" Beveled Cross Slip Joint US Imperial? They both
offer different parameters for D1 thru D4 and "appear" identical.

Regards from Santa Monica,

Emmanuel

Hi Emmanuel -

On Round Duct Beveled Cross Slip Joint US Imperial you can only select
connector sizes for D1, D3, and D4 as D2 = D1.
On Round Duct Transition Beveled Cross Slip Joint US Imperial you can select
connector sizes for all 4 connectors (D1 is not required to be equal to D2).

Hi Jason,

I see. Thank you. So one is a subset of the other.

I've been wondering what is the best way to deal with air return systems
where the air flow goes from small diameter pipes to bigger. The beveled
edges usually point in the wrong direction for this. Any suggestions on how
to deal with this?

Emmanuel

"So one is a subset of the other."

Well, the # of part that can be created by one is a subset of the other, but
it really wouldn't be fair to simply say that the "non - transition" is a
subset of the transition. They are different parts with different rules. It
seems like a very subtle difference, but is actually viewed as a completely
different part from the standpoint of the application. The application has
no idea that the parts are even similar except for the fact that they are
both round crosses.

The "default" direction of the bevels has more to do with the direction in
which the duct was drawn than the flow direction. Play with it a little and
you will see some tendencies on the default direction for bevels.

Thank you for clarifying this. What are some of the rules you refer to? Flow
directions?

Assuming I've played with it and still have problems, what is the proper way
of fixing their orientation? I've been using AutoCAD's mirror3D about the x-
or y-axis and then rotating 180 degrees. However, I'm concerned there may be
some problems lurking with this approach that I may not be aware of.

Hi Emmanuel,

You can use the Duct Fitting Properties command to fix the rotation of
beveled fittings. Try 'Flip Y' in the Anchor page.
