How to modeling rectangular ducts with specific inner bend radius or reduction length in the new MEP

[jiratm]

Hi everyone,

I’m trying to model rectangular HVAC ductwork using the new MEP Modeler with specific dimensions (see attached file).
My main question is: how can I define the inner bend radius (or the inner offset distance) of an elbow? How to a reduction specified by length, not by edge angle?

Additionally, I’d like to know if it’s possible to create asymmetric branches and reductions, or bends with changing cross-section using the new MEP tools.

And one more question — is it still possible to model a route element by element as before, instead of using only the automatic routing method?

Thanks in advance for any tips or workflow suggestions!

Does the new MEP Modeler actually respect the rectangular duct route presets correctly?
No matter what values I set in the Route Preferences, the elbows and branches of rectangular ducts are generated with different dimensions than expected. Am I doing something wrong?
Can someone recommend the correct workflow for this?

How can I correctly model a SPIRO duct end termination with an integrated grille (as a single element/product)?

Is it really true that no one is solving a similar problem?
